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
