Press the assigned programmable key to activate the
Talk Around feature when you are operating on du-
plex channel systems (separate receive and transmit
frequencies, utilizing a "repeater" station). The Talk
Around feature allows you to bypass 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 receive and transmit
frequencies are already the same.
In the 16-key and 4-key versions, 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.
