Automatic Time-Out Timer
If the selected channel has been programmed for au-
tomatic time-out, you must limit the length of each
transmission. While transmitting, a beep will sound

just before the deadline; the “TX” indicator will dis-
appear and transmission will cease soon thereafter.
To resume transmitting, you must release the PTT
switch and wait for the “penalty timer” to expire.
