Conventional Mode Features
5.5 Penalty Timer
A penalty timer may be programmed on conventional systems to prevent transmissions for
the programmed time after the time-out timer disables the transmitter (see Section 4.4).
The penalty timer can be programmed for the same times as the time-out timer, and timing
starts when the PTT switch is released. If the PTT switch is pressed during the penalty
time, the time-out indication occurs again and the transmitter remains disabled. When the
penalty timer expires, a beep sounds and the transmitter can be keyed.
5.6 Conversation Timer
A conversation timer can be programmed on conventional systems in addition to the time-
out timer (see Section 4.4). This timer limits the 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 Talkaround
Normally, all transmissions go through a repeater which usually increases range.
However, there may be times when a user is out of range of the repeater and therefore
unable to talk to anyone even though the user 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 radio-to-radio
communication.
Repeater talkaround 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 scanning, and changing channels or turning power off does not
change the selected condition. Talkaround is available on conventional channels only, and
power output is reduced in this mode.
