can be configured for several different types of decode 
operation. If a channel is selected that has Selcall 
activated the radio will be muted until the proper signal is 
received. When this occurs the radio can sound a ringing 
type alert signal or a voice message maybe heard. 
Depending upon the initial programming, pressing the 
PTT may cause an automatic identifier to be sent. When 
programmed for Selcall pressing the monitor and function 
buttons at the same time can cause the Selcall mode to 
be cancelled and generate an automatic identification. 
Please have your radio technician or dispatcher fully 
explain this operation.

  When you put a battery in the rear cup of the charger the 

charger checks the voltage. If voltage is over 7.4V, the 
charger starts discharging for 4 minutes then checks 
again. If voltage is still more than 7V, it discharges until 
the voltage is 6V then starts charging.
