Trunked Mode Operation, Receiving a Call | Orion LBI-38888K guide

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 signalling 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 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 signalling 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).
