5.7 CONVERSATION TIMER
A conversation timer can be programmed on
conventional systems in addition to the time-out timer
(see Section 4.3). This timer limits the total length of a
conversation rather than just the length of each trans-
mission as with the time-out timer. The following is
more information on this timer.
• It can be programmed for times up to 7.5 minutes.
• It is reset when the time between transmissions
exceeds the time programmed for the penalty timer.
• A warning beep sounds 5 seconds before this timer
disables the transmitter.
• When this timer disables the transmitter, a contin-
uous tone sounds and the red transmit indicator
turns off. The PTT switch must then be released
until the penalty timer expires (indicated by a beep).
5.8 REPEATER TALK-AROUND
Normally, all transmissions go through a repeater
which usually increases range. However, there may be
times when a mobile is out of range of the repeater and
therefore unable to talk to anyone even though the
mobile being called is only a short distance away. To
allow communication in this situation, repeater talk-
around can be selected. Transmissions then occur on
the receive frequency which permits direct mobile-to-
mobile communication.
Repeater talk-around can be selected if the RTA
option switch or menu parameter is programmed.
When talk-around is enabled by this switch, is
displayed. This feature remains enabled during scan-
ning, and changing channels or turning power off does
not change the selected condition. Talk-around is
available on conventional channels only.
5.9 DISPLAYING TRANSMIT/RECEIVE
FREQUENCY
If the Displayed Information option switch or
menu parameter is programmed (see Section 4.1), it can
be used to display the channel frequency in megahertz.
Pressing this switch toggles between displaying the
standard channel alias and the channel frequency. The
receive frequency is displayed when receiving and the
transmit frequency is displayed when transmitting. This
feature is available on conventional channels only.
5.10 EMERGENCY ALARM AND CALL
NOTE: The following enhanced conventional emer-
gency features require 5100 operating (Flash) soft-
ware 1.8.0 or later and PCConfigure 1.19 or later.
5.10.1 INTRODUCTION
Emergency Alarms and Calls are separate func-
tions that can be individually enabled or disabled on
each analog and P25 conventional system. The Emer-
gency option switch or menu parameter is required for
these functions. Emergency Alarms and Calls are
transmitted on the last selected talk group.
The emergency hot microphone function can also
be programmed with emergency alarms and calls.
Then when the emergency switch is pressed, the
microphone audio is enabled and the transmitter auto-
matically keyed for the programmed hot microphone
time (10-120 seconds). If “silent” emergency is
programmed, no tones sound but the transmit indicator
still lights. If the “Surveillance Mode” is enabled (see
Section 4.7), all indicators, lights, and tones are
disabled.
5.10.2 EMERGENCY ALARMS
An emergency alarm is a special transmission on
the selected talk group that alerts a dispatcher of an
emergency situation. It is sent by simply pressing
Emergency option switch or selecting the Emergency
menu parameter on channel of a system programmed
for emergency alarms.
In the P25 conventional mode, a special emer-
gency data transmission is sent, and in the conven-
tional analog mode, it is a DTMF number that is sent
in place of the Pre/Post ANI programming if appli-
cable. If ANI is not programmed, it defaults to the
“Pre” condition. The DTMF Emergency ID is
programmed on the Conventional Radio Wide screen
when programming the radio. Proceed as follows to
activate an emergency alarm:
1. Select a channel of a system on which the Emer-
gency Alarm is enabled and then press the Emer-
gency option switch or select that menu parameter.
The radio then begins automatically transmitting an
emergency alarm and “EMERGNCY” is indicated
in the display for 3 seconds.
