FM Transceiver

Receiving
You can hear the transmitting party's calling when the channel  you are operating  is called and the 
LED light turns green.
NOTE:
You may not receive the calling if you set a high squelch off level of the transceiver.
If  current  channel  has  been  programmed  with signaling,  you can  only  hear  the call  from  a  same 
signaling, other calls can not be heard. 
Channels Selection
Under  the standby  conditions,  turn  channel  selector  knob  to  choose  the  desired channel, and 
the  transceiver  will  announce  the  adjusted  channel.  Turn  clockwise  to  increase  the  channel, 
anticlockwise to decrease the channel. 
NOTE: The transceiver will emit a voice prompt when current channel is blank and the red light will flash.
BASIC OPERATIONS
Monitor
Pressing the  programmed key  of Monitor  [PF1]/[PF2], the transceiver  emits "DU" beep and  then 
comes into  the monitor state.  Under these conditions, transceiver will ignore CTCSS/DCS decode 
and monitor signal of the other party as long as receiving the matched carrier wave. Press this key 
again, transceiver emits "Du Du" beep and exits the monitor state.
