3.4. Transmitting and receiving
When the radio is switched on, it is automatically in receive mode as long as you are not transmitting.
When a radio message is received, the message RX appears in the display. Adjust the desired volume
with the VOL▲ and VOL▼ buttons. After 10 seconds of inactivity, the backlight turns off to save
power. The unit can still receive radio transmissions.
To transmit, press and hold the PTT (transmit) button and speak into the microphone at normal volume
and about 5 cm away. The message TX appears in the display. Release the PTT button at the end of
your transmission. To avoid accidental continuous transmission, the unit interrupts transmissions after
one minute and emits a warning tone instead. To continue transmitting, release the PTT button briefly
and then start another transmission.
Before transmitting, make sure the channel is clear by waiting a few seconds for any radio calls from
other participants.
