Note: If no station name is registered,

Rx frequency is soon displayed.

Figure 1-8 How to display Rx frequency and station name alternately

1.10 Transmitting

After selecting class of emission and frequency, you can transmit by pressing the PTT (press- to-talk) switch on the microphone (handset). (???T??? appears when the PTT switch is pressed. Output power can be evaluated on the operation display. Do not transmit any signal other than emergency during the silence period, 00 to 03 min, and 30 to 33 min of every hour.

Tuning the antenna

Maximum transmission power is achieved only when the antenna impedance and transmitter impedance match each other. Because the antenna impedance changes with frequency a means must be provided to match (tune) the antenna impedance with the transmitter impedance. This is done with the antenna coupler. The antenna coupler automatically tunes the transmitter to a wide range of different antenna length (6 ??? 15 m). To initiate the automatic tuning, do the following:

1.Press the PTT switch on the microphone (handset), or the [TUNE/7] key.

2.???TUNE??? appears on the display.

3.Tuning will be completed within 2 to 15 seconds for a newly selected frequency, or less than 0.5 seconds for a once tuned frequency. (A built-in memory remembers coil and capacitor settings.)

4.When the tuning process is successfully completed ???OK??? appears.

Reducing transmitter power

To conserve energy and to minimize possible interference to other stations, reduce the transmis- sion power. This should be done when using the transceiver in a harbor, near the shore or close to communication partner (other ship). Each pressing of the [H/L /8] key selects high or low output power. ???LOW??? appears on the display when low output power is selected. The output power on 2182 kHz (distress and calling) is the rated maximum regardless of the position of the [H/L /8] key.

1.11 Distress Call on 2182 kHz

The frequency 2182 kHz is an International radiotelephony distress, urgency and safety fre- quency for ship stations, public and private coast stations, and survival craft stations. It is also used for call and reply by ship stations on a primary basis and by public coast stations on a secondary basis.

Distress or emergency call is generally initiated by a radiotelephone alarm signal on 2182 kHz. Watch keeping receivers on other parties will hear your call.

1.Press the [2182] key. 2182 kHz and the class of emission H3E is automatically selected (J3E may be selected depending on system setting).

When the [2182] key is pressed, the following parameters are set automatically:

AGC: ON

Output power: Maximum

Loudspeaker: ON

Squelch: OFF

1-11

(2)The name of the mobile station in distress;

(3)Particulars of its position (in latitude and longitude)

(4)The nature of the distress;

(5)The kind of assistance desired;

(6)Any other information which might facilitate rescue, for length, color, and type of vessels, number of persons on board.

4.Indicate the end of message by saying ???Over.???

5.When you receive no answer to a distress message, repeat at intervals over again the radio- telephone alarm signal, the distress call and the distress message.

Distress frequencies

All distress frequencies including 2182 kHz are shown below:

For other Telex frequencies, refer to APPENDIX.

1-12

1.12 Receiving

You can select a receiving frequency by one of the following methods:

-Direct frequency entry, or

-Channel number entry

Adjusting RF gain

In normal use the [RF GAIN] control should be set for maximum. If the audio on the received channel is unclear or interfered with other signals, adjust (usually reduce) the control to im- prove clarity.

Clarifier adjustment

If reception is unclear, try to clarify the signal as follows. For manual entry of frequency, sim- ply turn the [FREQ/CH] control for fine tuning.

1.Press the [CLARI/3] key. (If a frequency is selected by CH No., the cursor which was located at the channel number, moves under the 10 Hz place and ???CLAR??? appears on the display.)

2.Turn the [FREQ/CH] control to fine tune the receiver on the wanted frequency.

3.To terminate this operation, press the [CLARI/3] key again. The cursor returns to the chan- nel number.

S-meter

During reception, the meter works as a Sensitivity Meter indicating the relative signal strength coming into the receiver front end. While in transmission, it indicates output level at the trans- ceiver.

0 2 4 6 8 10 S

Figure 1-11 S-meter

Note: S-meter will not work with AGC off.

Monitoring traffic on intended transmit frequency

When a semi-duplex (two-frequency simplex) channel is selected, it is recommended to moni- tor it if there is no existing traffic on the frequency you are going to use. To do this, press the [RX] key followed by the [ENT] key. The transceiver unit monitors traffic on the selected frequency for three sec. If you want to monitor continuously, press the [TX] key followed by the [ENT] key.

Receiving AM broadcasting stations

1.Press the [MODE/1] key repeatedly to select H3E.

2.To tune in a 15,260 kHz shortwave station, for instance, press as below: [RX], [1], [5], [2], [6], [0], [0], [ENT]. Be sure to enter the last zero.

Squelch control

Squelch is used to mute the receiver audio output when the receiver input is less than a preset value or dominant noise is higher than a preset (1000 Hz) frequency. To switch the squelch function ON, press the [SQL/5] key. Make sure the label ???SQ??? appears on the display. To pick up a weak signal at high audio frequencies, you should remove the squelch function notwith- standing a possible increase of background noise. To do this, press the [SQL/5] key again. Make sure the label ???SQ??? goes off.

Noise blanker (NB)

The noise blanker clips inputs of noise resulting from an engine ignition or motor brush sparks. It can be enabled or disabled through the system settings.

1.13 Frequency Scan

Channel scan

Scan is the function where the receiver watches 10/group user or ITU channels in succession at predetermined intervals. The scan-stop signal level and scan-stop time can be changed on sys- tem codes 9951 and 9952, respectively. AGC is automatically turned on when scanning is acti- vated.

1. Recall user or ITU channel.

User channels

User channels are divided into 20 groups in the scan mode as below.

Figure 1-12 Scan groups

1-15

ITU channels

To select the scan group (band or channel, including user channels), shift the cursor to either the position of the band or channel number by pressing the [CURS/2] key. (Band scan is useful to watch frequencies on the same channel in different bands.)

2.Press the [SCAN/6] key, and ???SCAN??? appears. The receiver starts scanning, stopping at a channel where the signal is stronger than the scan-stop level. The receiver will restart scan- ning when the traffic goes out of that channel or designated time elapses, depending on system setting 9952.

For example, the scan group is ???channel??? and scan starts at ITU 1203, as shown in Figure 1- 12.
