Programmable Auxiliary Functions

Your dealer can program the following auxiliary functions to the programmable keys
PF1-PF6.

Reverse Frequency

If communications between radios are disrupted because of a long distance from the
repeater, reverse frequency function can be used to re-establish communications to
another radio. When the function is activated, the transmit frequency and receive
frequency will be reversed. The corresponding CTCSS/DCS encoding and decoding
signals will also be reversed.
Press the key programmed as [Reverse] to toggle the reverse frequency function ON and
OFF.

Talkaround

If Talkaround is programmed, the transmit frequency can be changed to be the same as
the receive frequency. The CTCSS/DCS encoding signals also change to be the same as
the decoding signals.
Press the key programmed as [TA] to toggle the Talkaround function ON and OFF.
