t Wait for the channel to become clear.
The channel is busy when appears.
y Push the [CALL] key when initiating a call from your side.
Coded audio may be heard from the transceiver, then appears. This operation may not be necessary depending on your signaling system. Ask your System Operator or Dealer. u While pushing and holding [PTT], speak into the micro-
phone at your normal voice level. i Release [PTT] to receive.
Time-out timer After continuous transmission for a pre-programmed period, the time-out timer is activated causing the transceiver to stop transmitting and automatically select receive. Penalty timer Once the time-out timer is activated, transmission is further inhibited for a period determined by the penalty timer.
OPERATION D Tx code channel selection
If the transceiver has a [TX CH] key, display can be toggled between the operating channel number (or name) and Tx code channel number (or name).
