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 obtain 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 current
system and group names.
5. The radio is now ready to receive calls.
6. When the radio receives a group call, it un-mutes 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).
4. Hold the microphone approximately three inches from the mouth and
speak in a normal voice.
5. Release the PTT button when the transmission is complete and listen for a
reply.
