Conventional Features
If the emergency call is sent on a P25 channel, an emergency indication is sent according
to the P25 standard (the emergency bit is set in the Common Air Interface). If it is sent on
an analog channel, the DTMF Emergency ID is sent in place of the ANI DTMF PTT ID if
applicable.
Note The DTMF Emergency ID is sent only if pre- or post- DTMF ANI is enabled on the
channel by programming.
5.9.3.1 Emergency Hot Mic
If Emergency Hot Mic has been enabled for emergency calls for the system, automatic
transmitting occurs with microphone audio unmuted without having to manually press the
PTT switch. The automatic transmit period is programmed for 10-120 seconds in ten-
second intervals. If this feature or emergency calls are not enabled, automatic transmitting
does not occur. This feature is initiated only on the first press of the Emergency switch.
Subsequent presses do not trigger automatic transmissions. To reset this function, hold
emergency button or cycle power.
5.9.3.2 Placing an Emergency Call
To place an Emergency Call:
1 If required, select a channel of a system on which Emergency Calls are enabled and
press the EMER option switch. The Emergency Call is then sent as described in Section
5.9.1 if applicable.
2 If the preceding Emergency Hot Mic feature is enabled, the call is automatically
transmitted without pressing the PTT switch. If it is disabled, press the PTT switch and
begin speaking as with a standard call. If the channel is changed, operation continues
on the new channel in the emergency mode.
3 With analog calls, subsequent presses of the PTT switch cause the DTMF emergency
ID to be sent according to the ANI programming (if DTMF ANI is enabled on the
channel). With digital calls, the calls continue to have the emergency bit set.
4 If the Surveillance Mode is enabled (see Section 4.10), all indicators, lights, and tones
are disabled. If “No Receive Activity During Emergency” is programmed, receive
audio, the front panel LED, and receive icons are disabled in the receive mode.
5 To exit this mode, cycle radio power or press and hold the Emergency switch.
