NOTE

High power mode can improve the clarity of voice activity in areas where signals are weak while low power mode extends battery life.

Basic Operations

Transmitting a Message

???Select the desired channel or frequency (see

???MHz Mode Operations??? and ???Memory Mode Operations??? on pages 25 and 31).

???Press and hold the Monitor Button (5), and listen for channel activity.

NOTE

If the selected channel is in Carrier squelch mode - CTCSS indicator is not displayed on the LCD Screen (18), you can skip step ???.

???If the channel is clear, press the Push-To-Talk (PTT) Button (6) and speak clearly into the Micro- phone (11) (see ???Information For Safe, Ef???cient Operation??? on page 62 for more information).

TX

NOTE

Unless disabled (???dot??? indicator ???ashes on the LCD Screen (18)), PTT ID tones are heard as they are being transmitted (see ???PTT ID??? on page 17). You can start your conversation when the tones end.

NOTE

The TX indicator lights up on the LCD Screen (18) when the Push-To-Talk (PTT) Button (6) is pressed.

Basic Operations

IMPORTANT

Whenever you transmit a message, you are using the resources of the transmitting channel. Speaking for long periods of time would deprive others from using that channel.

NOTE

The maximum duration for transmission is deter- mined by the value of the Time-Out-Timer (see

???Editing Time Out Timer??? on page 53). Once you reach the time limit, a ???Time-Out Timer Alert??? tone is sounded, and the transmission is cut off.

Receiving a Message

???If the Push-To-Talk (PTT) Button (6) is pressed, release it and listen for incoming messages.

NOTE

Make sure the volume level is set properly, or else you may receive a message but are unaware about it.

Additional Operations

Additional Operations

Display Backlight

???Press the Toggle Light / Enter and Parameter Transfer Button (4) to turn on / off the backlight.

NOTE

To conserve power, the backlight is programmed to automatically turn off after 5 seconds.

NOTE

Pressing either the Push-To-Talk (PTT) Button (6) or the Monitor Button (5) has no effect on the back- light.

PTT ID

If programmed, the radio transmits a DTMF identi???ca- tion code (unit ID), indicating which portable is in oper- ation.

During a conversation, the code is normally sent only on the initial PTT press (unless PTT ID has been dis- abled). The ???TX??? indicator lights for the duration of the PTT ID. If there is no PTT or receive activity for 7 sec- onds, or if you change the frequency or channel (or scan resumes), the PTT ID is once again transmitted on the next PTT press.

??? Press and hold to enable / disable PTT ID.

NOTE

Upon pressing , you will hear a beep. Hold the button down until you hear a second beep, indicat- ing that the PTT ID status has been changed.

When PTT ID is disabled, the ???dot??? indicator ???ashes on the LCD Screen (18).

Additional Operations

Locking / Unlocking the Radio???s Function

Locking the radio will disable all buttons except the

Toggle Light / Enter and Parameter Transfer Button (4), Monitor Button (5), Push-To-Talk (PTT) Button (6) and . Pressing a locked button will result being shown on the LCD Screen (18). To lock / unlock the radio:

???Press and hold (for about 2 seconds) until two beeps are heard.

NOTE

The lock / unlock status remains unchanged even when the power is turned off.

Changing Squelch Modes

Squelch acts as a kind of ???ltering system which helps to control the amount of signals the radio receives. Con???guring the radio to receive only the desired sig- nals minimizes interference from other users of the same channel.

This radio supports Carrier Squelch (CSQ), Coded Squelch - Tone Private-Line (PL), Digital Private-Line (DPL) and Signalling Squelch - Voice Selective Call (SelCall) operations on a per channel basis.

Carrier Squelch transmission allows all radios tuned to the selected receive channel (frequency) to hear the conversation. Coded Squelch transmission only allows radio(s) having the same PL / DPL code on the selected receive channel (frequency) to hear the con- versation. Signalling Squelch transmission can only be decoded by radios equipped with optional DTMF Decode boards with valid Voice Selective Call (Sel- Call) identi???cation code (see ???Voice Selective Call (Optional)??? on page 44).

Additional Operations

NOTE

To perform Signalling Squelch (SelCall) operation, the radio must be equipped with an optional DTMF Decode board.

To temporarily override the default receive squelch mode for the channel:

SIG

??? Press A to change between Carrier (CSQ), Coded (PL /DPL) and Signalling (SelCall) squelch modes.

CTCSS

NOTE

The ???CTCSS??? indicator lights up continuously when the radio is operating in Coded (PL / DPL) mode, ???ashes when operating in Signalling (SelCall) mode and is not displayed when operating in Carrier (CSQ) mode.

NOTE

When transmitting in Signalling squelch mode, PL / DPL is transmitted (unless it is programmed to ???000???). After PTT is released, the radio automati- cally enters into CSQ mode for a period of time. If there is no receive activity, the radio resumes Sig- nalling squelch mode.

NOTE

Whenever you switch from one channel to the other, the default squelch mode of the new channel takes effect.

Additional Operations

NOTE

Using this procedure in Memory mode to switch from one squelch mode to the other, does not affect the default squelch mode for the channel. Each time you turn the radio off and on again, or when you switch to another channel and back again, the radio reverts back to its default squelch mode.

Setting Squelch Level

An open (low) squelch level sets the threshold for the receiving signal strength to be low. This means that the radio would receive a great variety of signals, both weak and strong. A tighter (higher) squelch level raises the threshold, thus ???ltering weak signals and only accepting the stronger ones. To set the squelch level:

???Rotate the Selector Knob (2) to select the desired squelch level.

???Press the Toggle Light / Enter and Parameter Transfer Button (4) (or any other button) momen- tarily to adopt the selected squelch level and return to normal operating mode.

IMPORTANT

The radio automatically adopts the new squelch level and returns to normal operation after 5 sec- onds of inactivity.

Additional Operations

NOTE

If you reach the upper (???15???) or lower (???00???) limit of the squelch range, the squelch level does NOT wrap around to the opposite limit but remains where it is.

Selecting The Receive PL / DPL Squelch Code

NOTE

Receive PL / DPL squelch code selection can only be done in MHz mode.

There are 126 different Receive PL / DPL codes avail- able, numbered from 001 to 126 (see ???Receive And Transmit PL / DPL Code Tables??? on page 23).

NOTE

Receive PL / DPL code ???000??? represents Carrier squelch.

xxx represents the active Receive PL / DPL code number).

???Rotate the Selector Knob (2) to select the desired active Receive PL / DPL code.

???Press the Toggle Light / Enter and Parameter Transfer Button (4) (or any other button) momen- tarily to adopt this Receive PL / DPL code and return to normal operating mode.

IMPORTANT

The radio automatically adopts the new Receive PL / DPL code and returns to normal operation after 5 seconds of inactivity.

Additional Operations

Selecting A Transmit PL / DPL Squelch Code

There are 126 different Transmit PL / DPL codes avail- able, numbered from 001 to 126 (see ???Receive And Transmit PL / DPL Code Tables??? on page 23).

NOTE

Transmit PL / DPL code ???000??? represents Carrier squelch.

xxx (where xxx represents the active Transmit PL / DPL code number).

???Rotate the Selector Knob (2) to select the desired active Transmit PL / DPL code.

??? Press the Toggle Light / Enter and Parameter Transfer Button (4) again to program the selected memory channel.

Memory Mode Operations

NOTE

The radio remains in MHz mode after successful programming of the channel.

CAUTION

If the selected memory channel was already pro- grammed (channel number lit continuously), the new frequency information overwrites the previous information.

Loading A Memory Channel

The data of a memory channel (receive and transmit frequencies, TX offset type and offset frequency) can be copied over into the MHz mode.

This allows you to tune the radio in the MHz mode from the point speci???ed by the memory channel data.

In Memory mode:

???Rotate the Selector Knob (2) to the desired mem- ory channel number.

???Press and hold Toggle Light / Enter and Parame- ter Transfer Button (4) for about 3 seconds.

NOTE

A valid keypress tone sounds when the memory channel data has been successfully copied over to the MHz mode.

Scan Operations

Scan Operations

Scan operation tells the radio to monitor a number of frequencies or channels. When there are some activi- ties at a particular frequency or channel, the radio stops scanning and changes to that frequency or channel.

Scan modes supported by the radio are:

(i)Programmable Band scan (MHz mode)

(ii)Memory Channel scan (Memory mode)

NOTE

Each frequency or channel is given the same prior- ity i.e. non-priority scan.

IMPORTANT

The radio will not recall the scan state if it is pow- ered off while scanning.

Programmable Band Scan

In the MHz mode, the radio scans over a prepro- grammed range of frequencies usually speci???ed in memory channels 19 and 20.

NOTE

User can specify the frequency range for scanning by programming the frequency limit into memory channel 19 (usually the lower limit) and memory channel 20 (usually the upper limit) (see ???Pro- gramming A Memory Channel??? on page 32).

Scanning A Frequency Range

In MHz mode:

frequency range.

NOTE

The frequency range is scanned according to the frequencies speci???ed in channels 19 and 20, and the selected frequency step size. If the operating fre- quency before scanning starts is within the scan range, the radio starts scanning from that fre- quency, otherwise, it starts from the frequency speci???ed by memory channel 19 (or the lowest fre- quency in the band if channel 19 is blank).

NOTE

When the ???SCAN??? indicator ???ashes, scanning is in progress and the currently scanned frequency is dis- played.

To change the scan direction:

??? Rotate the Selector Knob (2) anti-clockwise.

NOTE

If activity is detected, the radio stops scanning and stays on the active frequency. The ???SCAN??? indicator remains on, and you will hear the conversation, pro- vided the PL/DPL code (if required) is correct.

IMPORTANT

Radio resumes scanning after approximate 5 seconds (even if activity is still received). If

received activity ceases, the radio resumes scan- ning after another 7 seconds, unless receive activ- ity resumes.

Scan Operations

NOTE

Pressing Push-To-Talk (PTT) Button (6), a digit on the numeric keypad, or also ends the scanning.

NOTE

The ???SCAN??? indicator turns off when scanning is terminated and the radio displays the frequency where scanning stopped.

IMPORTANT

If both memory channels are left blank (unpro- grammed), the radio scans the entire frequency band. If channel 19 is programmed but channel 20 is blank, the upper frequency limit becomes the highest frequency in the band. If channel 20 is pro- grammed but channel 19 is blank, the lower fre- quency limit becomes the lowest frequency in the band. If the frequency stored in channel 19 is lower than that stored in channel 20, then scan proceeds in an incrementing order otherwise, scan proceeds in a decrementing order.

Transmitting During Band Scanning

When the scan is locked at a frequency:

??? Press Push-To-Talk (PTT) Button (6).

IMPORTANT

As soon as Push-To-Talk (PTT) Button (6) is pressed, the radio exits band scanning and trans- mits the TX frequency which corresponds to the active RX frequency, plus or minus any selected TX offset. If the user-de???ned mode is selected (???+??? and ????????? indicators both on), the radio transmits the user- de???ned TX frequency.

Scan Operations

Memory Channel Scan

In the Memory mode, the radio scans all programmed memory channels that are also in the channel scan list.

NOTE

The scan list is edited using the Special Program- ming mode (see ???Special Programming Mode (SPM)??? on page 46).

NOTE

Channels may be temporarily removed from the scan list using a Nuisance Channel Delete feature (see ???Nuisance Channel Delete??? on page 38).

Scanning Memory Channels

In Memory mode,

NOTE

When the ???SCAN??? indicator ???ashes, scanning is in progress and the Home Channel (the active channel

received on another channel.

The channels are scanned in an increasing order (from lowest to highest). To scan in a decreasing order:

??? Rotate the Selector Knob (2) anti-clockwise.

Scan Operations

NOTE

The radio scans through all channels in the prepro- grammed scan list. If activity is detected, the radio stops scanning and stays on the active channel.

The ???SCAN??? indicator remains on, and you will hear the conversation, provided the PL/DPL code (if required) is correct. In Carrier squelch and Coded squelch modes, when activity is over and a 7-sec- ond ???hang time??? has expired, the display reverts to the Home Channel and scanning resumes.

To stop scanning:

SCAN

??? Press D .

N-DEL

Transmitting During Channel Scanning

When the scan is locked at a channel:

???Press Push-To-Talk (PTT) Button (6) to talk, release to listen.

IMPORTANT

The radio transmits on the current active TX fre- quency. But, if Push-To-Talk (PTT) Button (6) is pressed before the scan is locked at any channel, the Home Channel TX frequency is used.

Nuisance Channel Delete

When the radio is scanning, it would stop at any chan- nel within the scan list that has activity. A channel that generates unwanted signals continuously is called a Nuisance Channel. To temporarily remove the chan- nel from the scan list:

locks on the Nuisance Channel.

Scan Operations

NOTE

Two medium-pitched ???beeps??? are sounded indicat- ing the radio has temporary removed the Nuisance Channel from its scan list.

IMPORTANT

To add a deleted nuisance channel back into the scan list, exit and reenter the scan function or restart the radio.

Exposure To Radio Frequency Energy

In August 1996 the Federal Communications Commis- sion (FCC) adopted updated RF energy exposure guidelines for wireless products regulated by the FCC. Those guidelines are consistent with the safety stan- dards* previously set by both U.S. and international standards bodies. The design of your Motorola two- way radio complies with the FCC guidelines and these standards.

*American National Standards Institute (C95.1 - 1992);

*National Council on Radiation Protection and Measure- ments (NCRP-1986);

*International Commission on Non-Ionizing Radiation Pro- tection (ICNRP- 1986)

To assure optimal radio performance and to insure that exposure to RF energy is within the guidelines in the above standards, the following operating procedures should be observed:

For Portable Two-way Radios:

???For hand held operation, the radio should be held in a vertical position with the microphone one to two inches (2.5 to 5 cm) away from the mouth, and the antenna should be kept one to two inches (2.5 to 5 cm) from the head or body when transmitting.

???For body worn operation, the antenna should be kept at least one inch (2.5 cm) from the body when transmitting.

Information For Safe, Efficient Operation

Electromagnetic Interference/compatibility

Nearly every electronic device is susceptible to elec- tromagnetic interference (EMI) if inadequately shielded, designed or otherwise con???gured for electro- magnetic compatibility.

???Turn your radio OFF in any facilities where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy.

???Turn your radio off when on board aircraft when instructed to do so. Any use of the radio must be in accordance with Federal Aviation Administra- tion (FAA) and FCC regulations or crew instruc- tions.

CAUTION

???Do not use the radio with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result.

???All batteries can cause property damage, injury or burns if a conductive material such as jewelry, keys or beaded chains touches exposed termi- nals. The material may complete an electrical cir- cuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when placing it inside a pocket, purse or other container with metal objects.

Potentially Explosive Atmospheres

Areas with potentially explosive atmospheres are often, but not always, clearly marked. They include fuelling areas such as below deck on boats, fuel or chemical transfer or storage facilities; areas where the air contains chemicals or particles, such as grain, dust, or metal powders; and any other area where you

Information For Safe, Efficient Operation

would normally be advised to turn off your vehicle engine.

WARNING

???Turn your radio OFF when in any area with a potentially explosive atmosphere, unless it is a type especially quali???ed for such use (for exam- ple, FMRC Approved). Sparks in such areas could cause an explosion or ???re resulting in bodily injury or even death.

???Do not replace or charge batteries in a hazard- ous atmosphere. Contact sparking may occur while installing or removing batteries and cause an explosion.

Blasting Caps And Areas

WARNING

To avoid possible interference with blasting opera- tions, turn your radio OFF near electrical blasting caps or in a ???blasting area??? or in areas posted: ???Turn off two-way radio???. Obey all signs and instructions.

For Vehicles With An Air Bag

WARNING

An air bag in???ates with great force. Do not place objects, including portable or mobile two-way radios, in the area over the air bag or in the air bag deployment area. If improperly installed or placed wireless equipment is in the air bag deployment area and the air bag in???ates, serious injury could result.

Recycling / Disposal of NiCd Batteries

Recycling / Disposal of NiCd Batteries

The U.S. Environmental Protection Agency (EPA) clas- si???es used NiCd batteries as hazardous waste, unless certain exemptions apply.

At the end of your battery???s useful life, it can be recy- cled. However, recycling facilities may not be available in all areas. Under various state or local laws, such batteries must be recycled or disposed of properly, and cannot be dumped in land???lls or incinerators.

Motorola fully endorses and encourages the recycling of NiCd batteries. The following is a list of recycling facilities around the world, where you can ship your NiCd batteries post paid to be recycled:

Licensing & Service Information

Licensing & Service Information

Licensing

This radio operates on FM radio communication fre- quencies and is subject to the rules and regulations of the local communications governing agencies. These agencies may require that all operators using general mobile radio frequencies obtain a radio license before operating their equipment. To determine the speci???c requirements, contact your local communi- cations governing agency. This agency can supply information required to properly obtain and complete the license application form and various operational issues.

Service

Because this unit contains a radio transmitter, most local governments prohibit anyone from making inter- nal adjustments to the transmitter unless speci???cally licensed to do so by government regulations. If your radio fails to operate or any operational dif???culties arise, contact your local Motorola dealer.

Proper repair and maintenance procedures assure ef???cient operation and long life for this radio.

Troubleshooting

Troubleshooting

Radio is dead.

Possible Problem (1): Batteries may be dead (alkaline) or not properly charged (NiCd).

Solution :If the display does not light, or the ???BATT??? indicator ???ashes on and off, you should replace the alkaline batteries, or if you are using NiCd batteries, recharge them.

Possible Problem (2): Batteries may not be positioned correctly in the radio.

Solution :See ???Installing and Removing Batteries??? on page 8 for the appropriate battery installation instructions.

NiCd battery does not charge or last long enough.

Possible Problem (1): Battery may be incorrectly charged.

Solution :If you use a desktop charger, make sure the battery is positioned properly in the charger base. If you are using a wall charger, make sure that the LED on the charger glows red, indicating correct charging status. See ???Charging with Wall Charger??? on page 11 and ???Charging with Desktop Charger??? on page 12.

Possible Problem (2): Battery may not be fully charged.

Solution :Turn radio off while charging battery. Charging time will be doubled if the radio is turned on while charging.

Troubleshooting

Possible Problem (3): The battery life is based on a duty cycle where the radio is transmitting 5%, receiving 5%, and in standby mode 90% of the time. Usage that differs from this will change the typical battery life expect- ancy accordingly.

Solution :If you use your radio for a longer period of time than the standard duty cycle, you may need to recharge your battery again.

Possible Problem (4): Battery or charger contacts may be dirty.

Solution :Clean battery and charger contacts often.

Alkaline Battery does not last long enough (<10 minutes).

Possible Problem (1): Operating the radio at high power with alkaline batteries.

Solution :When used with alkaline batteries, the radio should operate at low power unless absolutely necessary.

NOTE

It is recommended to operate your radio in Low Power when using alkaline batteries. Using alkaline batteries in High Power might result a Low Battery Alert (3 low pitched tones) shortly after transmitting. This is NOT a malfunction. The alert sounds because alkaline batteries cannot maintain the power needed to transmit at High Power for a long interval. However, APC is immediately activated when this alert sounds. It automatically adjusts the radio???s power requirements to maintain the radio???s operation. Without APC, the radio would instead reset itself and refuse to transmit.

Troubleshooting

Radio will not talk to other radios in system.

Possible Problem (1): Radios may be on different fre- quencies, or having different Coded Squelch Codes.

Solution :Verify that frequencies and Coded Squelch Codes are the same for all radios in your talk group.

Hearing other conversations or noise on your radio.

Possible Problem (1): Users do not have exclusive use of frequencies. Frequencies must be shared using proper radio etiquette.

Solution :Use proper radio etiquette.

NOTE

Coded squelch screens out other users??? conversa- tions on your radio, but other users who share your frequency may still hear your conversations.

Limited talk range.

Possible Problem (1): Using your radio in basements, steel structures, concrete buildings, auto- mobiles, or heavy foliage decreases its range.

Solution :These are standard characteristics of transmitters. External magnetic mount antennas are recommended for best range when communicating in an auto- mobile. If the radio supports the High/ Low Power Output option, check that the radio is not in Low Power Transmit Mode; the ???LOW??? indicator on the LCD lights in this mode.

Troubleshooting

Possible Problem (2): Operating the radio while it is close to your body (i.e. in a pocket or on a belt) and while you are using audio acces- sories decreases its range because of the shielding effect of your body.

Solution :The higher the radio is held, the better the talk range. Use of audio accessories is only recommended in close range sit- uations for best results.

Possible Problem (3): The Carrier Squelch Level may be set too high.

Solution :Set the Carrier Squelch Level to a lower value (see ???Setting Squelch Level??? on page 20).

You hear constant static from speaker.

Possible Problem (1): The alkaline batteries may be weak (or the NiCd battery may be dis- charged).

Solution :Press and hold the PTT while looking at the LCD. If the ???BATT??? indicator ???ashes continuously while still holding the PTT, the batteries should be replaced or recharged.

Possible Problem (2): When using your radio around computers or electronic equipment, you may hear static or interference from these devices.

Solution :Enable Coded Squelch. Coded squelch screens out this type of interference (see ???Changing Squelch Modes??? on page 18).

You have tried a solution for any of the above symp-

Troubleshooting

toms, without success.

Possible Problem (1): The radio may need to be repaired.

Solution :If the unit is still under warranty, return it to the place of purchase for repairs, or contact your nearest Motorola dealer listed in your local yellow pages.
