T A TA
Press (or press and hold) the assigned Programmable
key to activate the Talk Around feature when you are
operating on duplex channel systems (separate re-
ceive and transmit frequencies, utilizing a "repeater"
station). The Talk Around feature allows you to by-
pass the repeater station and talk directly to a station
that is nearby. This feature has no effect when you
are operating on "simplex" channels, where the re-
ceive and transmit frequencies are already the same.
When the "TA" function is activated, the " " icon
will be indicated on the display.
Note that your dealer may have mode provision for
"Talk Around" channels by programming "repeater"
and "Talk Around" frequencies on two adjacent chan-
nels. If so, the key may be used for one of the other
Pre-Programmed Functions.
