3.5.Receiving a Call
When the radio receives RF signals on the selected channel and the squelch level is reached, the green
LED glows to indicate that carrier is received.
When the selected channel is digital channel and when it received individual call, group call or all call, the
radio will output the voice from the channel.
When the channel is analogue channel and when it received analogue signals with CTCSS matching the
one on this channel (or there is no CTCSS set on the channel), the radio will output voice form the channel.
3.6.Calling Back
When the selected channel is digital channel and after a call is received, press the PTT button within the
calling duration to call back. If the calling duration is up, you need to initiate a call. The calling duration can
be set by the dealer.
When the selected channel is analogue channel and after a call is received, press the PTT button and
speak to the microphone to call back.
