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 to establish initial contact
with another station and for emergency communication. This channel can be called up at any
time by pressing button 16 on both the transceiver. To return to normal operations, select
another channel using the alphanumerical keypad or the UP/DOWN buttons on the microphone.
By pressing a second time the 16 button, the radio returns to the previously used channel before
selecting channel 16.
Do not transmit on channel 16 unless absolutely necessary. Doing so may impede emer-
gency operations.
5.8 Display lighting
If ambient lighting is insufficient for reading the display, the LCD display backlighting can be
adjusted. Hold pressed the button until a desired level is reached or until it has been comple-
tely turned off. If the backlighting is activated, the display shows “LITE”.
The chosen level of backlighting remains stored, also in case of extinction and successive
turning on the radio.
If you desire to switch off the backlighting immediately or if you like to reactivate the previously
inserted level, press the button.
