10 ALERT TONES
The M7100
IP
series mobile radio also provides audible alert tones or "beeps" to indicate the various
operating conditions. These alert tones can be enabled or disabled through programming.
10.1 CALL ORIGINATE
A short mid-pitched alert tone sounds after keying the radio (Push-To-Talk button is pressed). This tone
indicates the radio has been assigned a working channel or that the radio is transmitting on a conventional
channel and voice communication can begin immediately. In conventional mode, this tone may be delayed
after the PTT button is pressed due to G-STAR™ signaling (if enabled through programming).
10.2 AUTOKEY (TRUNKED MODE ONLY)
After being placed in a 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.
10.3 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 sound(s) the tones to indicate they will receive a call shortly. If the PTT
button is released, the radio will autokey whenever a channel becomes available (see Autokey).
10.4 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 re-keying initiates a new channel request.
10.5 CALL DENIED (TRUNKED MODE ONLY)
If the radio is keyed and a low-pitched tone is heard, the radio is not authorized on the system that has been
selected.
10.6 CARRIER CONTROL TIMER
If the programmed time for continuous transmission is exceeded, the radio will issue five short high-
pitched warning tones followed by a long low-pitched tone. The transmitter will shut down shortly after the
alert, interrupting communications. Release and re-key the PTT button to maintain communications. This
will reset the carrier control timer and turn the transmitter back on.
10.7 KEY PRESS ALERT
A short tone or "beep" will sound to indicate a key has been pressed. A short low-pitched tone indicates no
action was taken because the key is not active in the current mode.
10.8 DUAL CONTROL SWITCHING
When control is switched to a previously idle control unit, two short high-pitched tones will sound at the
control unit where the PTT was pressed (now the active controller).
