Motorola GP380 Handset
On the left side (if facing the front) there are 4 buttons
The largest one is the PTT or Send Button as on the older models.
The topmost button is the Cancel/Monitor button. When pressed for 2
seconds it will disable the squelch, enabling the user to monitor the channel.
The bottom button also cancels an ongoing selcall.
The second from bottom, the Call Button, will make the radio send out a
selective call, either to individuals or groups within the GP Professional series
of radios.
The address (or ID) to transmit is chosen by the user.
The bottom button toggles the background lighting. Lighting should be set to
OFF to save battery power, and only to be used if required.
