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.
