2.3.13 PLACING AND RECEIVING STANDARD
GROUP CALLS
General
These calls are between two or more mobile or
control station transceivers. The main difference
between these calls and the other types is that no
number is dialed using the keypad. The following
procedure applies to all three types of operation (LTR-
Net, LTR, and conventional).
Placing a Standard Group Call
1. Turn transceiver power on and set the volume as
described starting with Section 2.3.1. With conven-
tional operation, also make sure that the squelch is
properly set as described in Section 2.11.4.
2. Select the system and group of the mobile being
called as described in Section 2.3.5.
3. If a conventional call is being placed, monitor the
channel manually or automatically as described in
Section 2.3.11.
4. Press (and hold) the microphone PTT (push-to-talk)
switch to talk and release it to listen. Operation with
LTR-Net, LTR, and conventional calls is as follows:
LTR-Net and LTR Operation
•
If tones are enabled, the proceed tone sounds
shortly after the PTT switch is pressed if the radio
system was successfully accessed (see Section
2.4.9). If tones are disabled, no tone sounds when
the system is successfully accessed.
•
If the radio system is busy, the busy tone sounds
(see Section 2.12) and "BUSY" is indicated in the
display. If the PTT switch continues to be pressed,
the system is accessed as soon as it is free.
•
If the radio system could not be accessed because
of an out-of-range condition or some other
reason, the intercept tone sounds (see Section
2.12) and "NO ACCES" is indicated in the
display. The PTT switch must then be released
and pressed again to make another access
attempt.
•
When responding, busy or no access conditions
may also occur the same as when placing a call
because the system is re-accessed for each
transmission with these calls.
Conventional Operation
•
If the channel is busy and the Transmit Disable
On Busy feature is programmed (see Section
2.11.3), "DSBL BSY" is indicated in the display
and the transmitter is disabled. Any channel
activity is heard while the PTT switch is pressed.
•
Otherwise, busy and out-of-range conditions are
not indicated and speaking can begin when the
PTT switch is pressed (if the channel is not busy).
If the proceed tone is enabled on conventional
systems, it indicates when speaking can begin but
does not indicate that the channel is free or has
been successfully accessed.
2.3.14 RECEIVING A STANDARD GROUP CALL
1. Select or scan the system and group programmed for
the call you want to receive (see Section 2.6.1 for
scan information).
2. When the message is received, the display changes
to the system and group of the call. Press the PTT
switch to talk and release it to listen. If scanning or
if a priority call is received, a response may not
automatically occur on the group of the call. Refer
to Section 2.6.10 for more information.
