5.6 Selecting high and low transmission power
The transmission phase absorbs the most energy. To reduce the risk of wearing out the battery, we
recommend selecting low transmission power when transmitting over short distances.
Hold the H/L button down (on the radio): Lo (low power) appears on the display. When transmitting
or receiving over long distances or with weak signals, press the H/L button again. Lo will be replaced
with Hi (high power) on the display.
When the transceiver is tuned to a channel limited to low output power, pressing the
H/L
button has no effect.
5.7 Instant recall of channel 16
Channel 16 is a security and distress channel. This channel is used for emergency
communications.
Press the 16 button (the red one on the keypad) and you will be tuned on the emergency channel.
To return to the channel previously used, simply press the 16 button again.
Do not transmit on channel 16 unless absolutely necessary. Doing so may impede
emergency operations.
