STANDARD CALLS
16
Placing 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
on page 14.
2. Select the channel of the mobile being called as described in “Channel
Select and Display” on page 14.
3. If a conventional call is being placed, monitor the channel manually or
automatically as described on page 30.
4. Press (and hold) the microphone PTT (push-to-talk) switch to talk and
release it to listen. Operation with LTR and conventional channels is as
follows:
LTR Operation
•
If the proceed tone is enabled (see page 24), it sounds shortly after
the PTT switch is pressed and it indicates that the radio system was
successfully accessed. If the proceed tone is not enabled, no tone
sounds when the system is successfully accessed. (The proceed and
other tones may have been disabled as described in “Tone Select” on
page 25.)
•
If the radio system is busy, the busy tone sounds (see page 35). If you
continue to press the PTT switch, the system is accessed when it
becomes available.
•
If an out-of-range condition exists, the intercept tone sounds and no
more access attempts are made until the PTT switch is released.
Drive closer to the radio system or away from shielding structures
and try again.
•
When responding to a call, busy or out-of-range conditions may also
occur as when placing a call because the system is re-accessed for
each transmission.
