5.6 Conversation Timer
A conversation timer can be programmed on conventional systems in addition to the time-
out timer (see
Section 4.2). This timer limits that total length of a conversation rather than
just the length of each transmission 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 five seconds before this timer disables the transmitter.
• When this timer disables the transmitter, a continuous 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).
5.7 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.
5.8 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.
