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.
