Chapter 1 OPERATION

1.1 SYSTEM SET-UP

The basic 24 VDC FS-1562 consists of a Transceiver Unit, a Power Amp Unit (for 250 W), an Antenna Coupler, and a Handset. Shown below are the system setup for 150 W and 250 W with DSC (Digital Selective Calling) terminal and other ancillaries.

1.3 Power Supply Unit

The transceiver unit FS-1562-15 or FS-1562-25 works direct on 24 VDC or through a Power Supply Unit on AC mains supply (115 or 230 VAC). The power supply unit is type PR-300 supplying 24 VDC power (20 A) to the FS-1562-15 (150 W) Transceiver Unit or type PR-850A, supplying 24 VDC (40 A) for the FS-1562-25 (250 W). Both 115/230 VAC and 24 VDC power can be connected simultaneously. In this case, the system normally operates on the AC mains supply and when AC power is lost, the PSU automatically switches to the DC power source.

This power supply arrangement satisfies the GMDSS requirements. The FS-1562-15/25 can be operated direct from 24 VDC without a rectifier unit.

OVEN power supply: The crystal oven is always powered even when the Power Switch is OFF. It draws 50 mA approx. The Oven LED lights while the oven is powered.

AC and DC power switches

Both AC and DC power switches on the PSU can be always kept ???on???. (These switches are provided to turn off the power supply for maintenance.) The transceiver may be turned on or off with the PSU kept on.

NOTE: You can recall an ITU channel by entering 3 or 4 digits. To recall ITU telex channel 4012 by three digits, for example, select ???TLX??? then enter 412 (instead of 4012).

-1.9-

1.6 Transmitting

After selecting class of emission and frequency, you can transmit by pressing the PTT (press-to-talk) switch on the handset or microphone. 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 (7 - 30 m). To initiate the automatic tuning, do the following:

???Press the PTT switch on the handset (microphone); or

???Press [7] TX TUNE key.

After one of the above is done;

1.???TUNE??? appears on the display.

2.Tuning will be completed within 2 to 5 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.)

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

Using the handset:

Hold the handset close to your mouth, press the PTT switch and speak clearly.

Monitoring transceiver output power:

During transmission, the meter deflects depending on the current being fed to the antenna feeder from the ATU. The unit of readout is amperes. The antenna current varies with the effective antenna impedance. The swing differs by the frequency or antenna length. The output power is proportional to the square of an antenna current. But don???t be very nervous about the meter swing.

Reducing transmitter power:

To conserve energy and to minimize possible interference to other stations, reduce the transmission 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 [HI/LOW] key selects high or low output power. ???LOW??? appears on the display when low output power is selected. Low power is 60 Wpep for FS-1562-15 and FS-1562-25, both. The output power on 2182 kHz (Distress and calling) and 2187.5 kHz (DSC) is the rated maximum regardless of the position of the [HI/LOW] switch.

If the optional AC FAIL Board is installed, Tx power is automatically reduced when AC power fails.

1.7 Distress Call on 2182 kHz

The frequency 2182 kHz is an International radiotelephony distress, urgency and safety frequency 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 (US CFR 47, ?? 80.369).

Distress or emergency call is generally initiated by a radiotelephone on 2182kHz.

When the FS-1562 is installed with a DSC Terminal as required on GMDSS vessel, press the DISTRESS switch on the DSC Terminal prior to commencing the vocal communications.

1.Press the [2182] key. 2182kHz in the class of emission J3E is automatically selected.

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

Output power: Maximum

Loudspeaker: On

-1.11-

2.Distress calls and Distress message

(1)Speak slowly and distinctly, ???MAYDAY, MAYDAY, MAYDAY, pronounced as the French expression ???m???aider???.

(2)This is;

(3)The name of your vessel and call sign three times.

Then, continue with the distress message, which consists of:

(1)The distress signal MAYDAY;

(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.

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

4.When you receive no answer to a distress message, repeat at intervals over again the radiotelephone alarm signal, the distress call and the distress message. Repeat the same on other distress frequencies.

Distress frequencies

All distress frequencies including 2182 kHz are shown below:

For other Telex frequencies, refer to Appendix.

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 monitor 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 3 seconds.

Receiving AM broadcasting stations:

1.Press the [1] MODE key repeatedly until H3E with AGC is selected.

2.To tune in a 15,260 kHz shortwave station, for instance, press as below: [RX], [1], [5], [2], [6], [0], [0], [ENT]. Do not miss the last zero.

-1.14-

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) level. To switch the squelch function ON, press the [5] SQUELCH 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 notwithstanding a possible increase of background noise. To do this, press the [5] SQ switch again. Make sure the label ???SQ??? goes off.

Noise blanker (NB):

Always in circuit. This function is to clip off inputs noise resulting from an engine ignition or motor brush sparks.

1.11 Frequency Scan

Channel scan:

Scan is the function where the receiver watches 10/group custom or ITU channels in succession at predetermined intervals. The scan-stop signal level and scan-stop time can be changed on system codes 9951 and 9952, respectively. Prior to the use of the scan function, turn AGC on.

1. Recall Custom or ITU channel

Custom channels

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

Chapter 2 OPERATION of

OPTIONAL DEVICES

2.1 Telex Communication

Telex communication is performed with a Narrow-band direct-printing (NBDP) Terminal connected with an SSB transceiver. The recommended terminal for the FS-1562 is FURUNO DP-6. Other makes can also be connected with the FS-1562, if they comply with the interfacing requirements.

FURUNO NBDP Terminal DP-6

No special operation is required; class of emission and frequencies are automatically set on the DP-6.

Other makes of NBDP Terminal:

1.Select ???TLX??? with the [1] MODE key.

2.Select a desired frequency.

3.Tune the antenna coupler by pressing the [7] TX TUNE key.

NOTE:

The DP-6 provides Forward Error Correction (FEC) mode to ensure quality communications. Continuous transmission on FEC can cause the transceiver internal temperature to go up beyond the temperature control sensor actuating point. When the internal temperature of the 150 W transceiver is above the sensor actuating temperature, the power is reduced to the LOW power. When the temperature goes down, the power is restored to the high rating. If this can cause an inconvenience of operation, it is recommend to install the fan kit (option), for added cooling effect.

The FS-1562-25, 250 W version, handles the high power in the Power Amp Unit PA-2500. The PA-2500 is provided with a cooling fan and not subject to the internal temperature rise. Continuous telex operation is possible with the high rated power.

Distress frequencies for telephony and telegraphy are as below. For other traffic frequencies, refer to Appendix.
