Conventional Operation

If the channel is busy and the Transmit Disable On Busy feature is
programmed, the busy tone sounds and the transmitter is disabled
(see page 33).
•
Otherwise, busy and out-of-range conditions are not indicated and
speaking can begin when the PTT switch is pressed. If the proceed
tone is enabled on conventional channels, it indicates when speaking
can begin but does not indicate that the radio system has been
successfully accessed.
5. When the call is finished, place the microphone back on-hook.
Receiving a Standard Call
1. Turn transceiver power on and set the volume as described starting on
page 14. With conventional operation, also set the squelch as described

(see page 25 for more information on scanning).
3. When the message is received, take the microphone off-hook and press
the PTT switch to talk and release it to listen. If scanning, a response
may not automatically occur on the channel of the call and the channel
may have to be selected manually.
