(Push-To-Talk) switch on the side of the micro-

in a clear, normal voice level, and then release the
PTT switch to receive.

Automatic Time-Out Timer
If the selected channel has been programmed for
automatic time-out, you must limit the length of
each transmission. While transmitting, a beep will
sound five seconds before time-out. Another beep
will sound just before the deadline; the "TX" in-
dicator will disappear and transmission will cease
soon thereafter. To resume transmitting, you must
release the PTT and wait for the "penalty timer"
to expire (if you press the PTT before this timer
expires, the timer restarts, and you will have to
wait another "penalty" period.)
