STANDARD CALLS
Introduction
Most calls you make are probably the standard type described in this
section. These calls are between you and another mobile or control
station. The main difference between these calls and the other type that
can be placed (telephone calls) is that no number is dialed using a
keypad. The following procedure applies to both LTR and conventional
operation.
Placing a Standard Call
1. Turn transceiver power on and set the volume as described starting on
page 15. With conventional operation, also set the squelch as described
on page 18.
2. Select the system and group of the mobile being called as described in
“Selecting the System and Group” on page 17.
3. If a conventional call is being placed, monitor the channel manually or
automatically as described on page 39.
4. Press (and hold) the microphone PTT (push-to-talk) switch to talk and
release it to listen. Operation with LTR and conventional systems is as
follows:
LTR Operation
• If the proceed tone is enabled (see page 28), it sounds shortly after
the PTT switch is pressed to indicate 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 can be disabled as described in “Tone Select” on page 30.
• If the radio system is busy, the busy tone sounds (see page 47) and
“BUSY” is indicated on the lower line of the display. If you continue
pressing the PTT switch, the system is accessed when it becomes
available.
