Conventional Mode Features
5.6 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 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 radio is out of range of the repeater and therefore
unable to talk to anyone even though the radio 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 talk-around can be selected if the RTA option switch is programmed. This
feature can also be selected via the menu. 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. The Talkaround capability can be Disabled on a per-channel basis, requiring the user
to use the infrastructure if disabled. (Radio-to-Radio communication is not allowed.)
5.8 Displaying Transmit / Receive Frequency
If the Display Information 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 may
also be selected via the menu and soft buttons (Lightning Control Head only).
