AUTOKEY
When the PTT is keyed to place a call on the system, but the PTT is released before the channel is assigned (e.g. a queued call), the radio automatically keys on the channel when it gets the assignment. The radio generates a long beep and holds the transmitter keyed for two seconds. Pressing the PTT button keeps the channel and sends the message before this two second
SYSTEM BUSY
If you key the PTT bar and hear three short, medium pitched tones, this indicates that the receiving party is already on the system or the system is busy and its queue is full. You must rekey later to access the system.
CALL DENIED
A single low pitch beep sounds when the PTT switch is keyed and the request is denied by the system. This happens if the unit is an invalid user or if the unit is requesting an unavailable service.
OUT OF RANGE SYSTEM INOPERATIVE
A single low pitched tone sounds immediately after the PTT switch is keyed indicating the radio is out of range of the repeater. The radio tries to place the call for a short period (3 seconds) after the initial attempt. The radio generates a second low pitched tone when it gives up trying to place the call. The system is off the air or the radio needs servicing when the radio is within calling range, and these tones are heard.
