2.1.6 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).

1. Rotate the [ENTER] knob to choose LOW, MID or HIGH (whichever is shown) at the
