Reducing transmitter power

To conserve energy and to minimize possible interference to other stations, reduce the transmis- sion 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 [H/L /8] key selects high or low output power. “LOW” appears on the display when low output power is selected. The output power on 2182 kHz (distress and calling) is the rated maximum regardless of the position of the [H/L /8] key.

1.11 Distress Call on 2182 kHz

The frequency 2182 kHz is an International radiotelephony distress, urgency and safety fre- quency 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.

Distress or emergency call is generally initiated by a radiotelephone alarm signal on 2182 kHz. Watch keeping receivers on other parties will hear your call.

1.Press the [2182] key. 2182 kHz and the class of emission H3E is automatically selected (J3E may be selected depending on system setting).

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

AGC: ON

Output power: Maximum

Loudspeaker: ON

Squelch: OFF
