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
Squelch: Off
