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.)

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 may also be selected via the menu.

This feature is available on conventional channels only.
