transmitter (see Section 3.9). The penalty timer starts
when the PTT switch is released after the transmitter
has been disabled. If the PTT switch is pressed during
the penalty time, the time-out indication occurs again.
When the penalty timer expires, a beep sounds and the
transmitter can then be keyed.
4.7 CONVERSATION TIMER
A conversation timer can be programmed on
conventional systems in addition to the time-out timer
(see Section 3.9). This timer limits that 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).
4.8 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 is programmed. When talk-around is
enabled by this switch, “RTA ON” is flashed in the
display, and when it is disabled, “RTA OFF” is
flashed. This feature remains enabled during scanning,
and changing channels or turning power off does not
change the selected condition. Talk-around is available
on conventional channels only.
4.9 DISPLAYING TRANSMIT/RECEIVE
FREQUENCY
If the DISP option switch is programmed, it can
be used to display the channel frequency in megahertz.
Pressing this switch toggles between displaying the
standard channel alias and the frequency. The receive
frequency is displayed while receiving and the
transmit frequency is displayed while transmitting.
This feature is available on conventional channels
only.
4.10 EMERGENCY MODE
An EMER option switch may be programmed on
conventional channels to alert a dispatcher or someone
else of an emergency condition.
When this switch is pressed with a Project 25
(digital) channel selected, all transmissions have the
emergency flag set. Scanning is disabled and the trans-
ceiver remains in the emergency mode until power is
cycled.
Emergency conditions are not transmitted when
an analog channel is selected. However, if it is pressed
on an analog channel and a Project 25 channel is
selected before power is turned off, the emergency
condition is transmitted on the Project 25 channel as
just described.
4.11 CONVENTIONAL MODE SCANNING
4.11.1 GENERAL
Channel scanning features common to all oper-
ating modes are described in Sections 3.16 and 3.17.
The following information describes features unique
to conventional operation.
4.11.2 SELECTING A SCAN LIST
Conventional mode scan lists are selected by
repeatedly pressing the Scan option switch. For
example, if three scan lists are programmed, the first
press of the Scan switch activates scanning and scan
list 1, the second press activates scan list 2, the third
press activates scan list 3, and the fourth press disables
scanning and then the cycle repeats. The currently
selected scan list is flashed in the display as “SCAN
