Programmable Auxiliary Functions; Reverse Frequency; Talk Around - HYT TM-600 VHF Manual

Programmable Auxiliary Functions

The [P1]-[P2], ▲/▼ are respectively programmable with one of the following auxiliary
functions by your dealer.

Reverse Frequency

If communications between radios are disrupted because of a long distance from the
repeater, the Reverse Frequency function can be used to re-establish communications
with another radio. When the function is activated, the transmit frequency and receive
frequency will be reversed. The preset CTCSS/CDCSS encoding and decoding signals
will also be reversed.
Press the Reverse Frequency key (programmable) to toggle the Reverse Frequency
function ON or OFF.

Talk Around

If the Talk Around feature is enabled, the Rx frequency is used in place of the Tx
frequency when transmitting, and the CTCSS/CDCSS decoding signal is used in place of
the encoding signal when encoding.
Press the Talk Around key (programmable) to toggle the Talk Around function ON or OFF.
