TRUNKED MODE OPERATION
Digital trunking provides fast communication access at all times, even
during busy hours. In this mode the operator selects a communications
system and group and the audio communication or working channel
(WC) is allocated through digital signaling with the site.
RECEIVING A CALL
1. Turn on the radio by rotating the POWER ON-OFF/VOLUME knob
clockwise (out of detente). A short alert signal (if enabled through
programming) indicates the radio is ready to use.
2. The display shows the last selected or the power up (depending on
programming) system and group names. If the radio is unable to ob-
tain a control channel, line two shows
CC SCAN
.
3. Adjust the POWER ON-OFF/VOLUME knob to the desired volume
level.
4. Select the desired system and group. The display indicates the cur-
rent system and group names.
5. The radio is now ready to receive calls.
6. When the radio receives a group call, it unmutes on the assigned
working channel and BSY indicator comes on. Line one shows
GR
followed by the logical ID number (if received) of the unit sending
the message, or the associated name if the ID number is found in the
individual call list.
SENDING A CALL
1. Turn on the radio and set the POWER ON-OFF/VOLUME knob to
the desired volume level. Select the desired system and group.
2. Press and hold the PTT button. The radio will display the system
and group names and perform the necessary signaling required to
obtain a communication channel.
3. When the working channel is assigned, TX and BSY indicators are
turned on and a short beep sounds indicating that communication
can begin. (NOTE: If two or more tones, or a high pitched tone is
heard, the system may be busy and the call request has been placed
in queue or the request has been denied for some reason. Refer to the
ALERT TONES section for more details).
