Furuno FS-1562-25, FS-1562-15 manual Distress Call on 2182 kHz, Reducing transmitter power

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.
