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
top of the screen and then push the [ENTER] knob.

2. Rotate the [ENTER] knob to choose power among LOW, MID and HIGH as
appropriate and then push the [ENTER] knob.
Note: Power amplifier temperature is monitored, and when its temperature rises above a
certain temperature output power is automatically reduced.
2.1.7 Displaying IA, IC, VC or RF
While transmitting, you may display RF (PA output), IA (antenna current), IC (collector
current) or VC (collector voltage), at the lower right corner of the radiotelephone screen.
1. Rotate the [ENTER] knob to choose RF, IA, IC or VC (whichever is displayed) at the
bottom right corner.
