The [CURS (cursor)] key shifts the cursor to band or channel number. To change the channel number, you can use the rotary control. The [FREQ/CH] control changes the number above the cursor, a band or channel designator.

ITU TELEX channels

To select the ITU TELEX channel 4012, for example, first select TLX with the [MODE] key. This radiotelephone is furnished with J2B class of emission. The J2B is compatible with F1B which may be used on other parties. You do not have to worry about F1B or J2B; you can just select TELEX mode for narrow-band direct-printing. Press [RCL], [4], [0], [1], [2], [ENT], and a combination of TX frequency of 4178.0 kHz and RX frequency of 4215.5 kHz is selected with the display as below. To select only RX or TX frequency, hit [RX] or [TX] to start with.
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).

1.6 Transmitting

After selecting class of emission and frequency, you can transmit by pressing the PTT (press-to-talk) switch Do not transmit any signal on the handset or microphone. Output power can be other than emergency during the evaluated on the operation display. 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 dont be very nervous about the meter swing.

-1.10-

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: Loudspeaker: Squelch: Maximum On Off

-1.11-

2. Distress calls and Distress message (1) (2) (3) Speak slowly and distinctly, MAYDAY, MAYDAY, MAYDAY, pronounced as the French expression maider. This is; The name of your vessel and call sign three times.
Then, continue with the distress message, which consists of: (1) (2) (3) (4) (5) (6) The distress signal MAYDAY; The name of the mobile station in distress; Particulars of its position (in latitude and longitude) The nature of the distress; The kind of assistance desired; 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.

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.
Telephony SSB (kHz, Carrier) 16 420
DSC (kHz, Center) 2 187.207.414.804.5
