ALERT TONES
The ORION radio also provides audible alert tones or "beeps" to indicate the various operating conditions. These alert tones can be enabled or disabled through programming.
CALL ORIGINATE
A short mid-pitched alert tone sounds after keying the radio (Push-To-Talk button is pressed). This indicates the radio has been assigned a working channel or that the radio is transmitting on a conventional channel and voice communication may begin immediately. In conventional mode, this tone may be delayed after the PTT button is pressed due to G-STAR signalling (if enabled through programming).
AUTOKEY (TRUNKED MODE ONLY)
After being placed in queue or releasing the PTT button prior to a working channel assignment, the site calls the radio when a channel becomes available. At this point, the radio automatically keys the transmitter (autokey) for a short period to hold the channel. The radio sounds a mid- pitched tone when it is clear to talk; immediately press the PTT button to keep the assigned channel.
CALL QUEUED (TRUNKED MODE ONLY)
A high-pitched tone after pressing the PTT button indicates the system has placed the call request in the queue. The receiving unit(s) also hear the tones, indicating they will receive a call shortly. If the PTT button is released, the radio will autokey whenever a channel becomes available (see Autokey).
SYSTEM BUSY (TRUNKED MODE ONLY)
Three low-pitched beeps will be heard if the radio is keyed when the system is busy, if no channels are available for sending the message, if the call queue is full, or if an individual call is being attempted to a radio that is transmitting. Releasing the PTT button and rekeying initiates a new channel request.
