In order to prevent accidental channel change or inad-
vertent transmission, various aspects of the CH Selec-
tor knob, Programmable keys, and PTT switch may be
locked. The precise lockout configuration is programmed
by your Dealer.
To activate the key locking, turn the radio off. Then, press
and hold the PTT and SIDE-2 key while turning the radio
on again.
To cancel the key locking, repeat this process.

This system is designed to inform the operator when you
and another ARTS™-equipped transceivers and stations
are within communication range using the DCS Encoder/
Decoder.
During ARTS™ operation, when the radio receives an
incoming ARTS™ signal, a short beep will sound. If you
move out of range for more than two minutes, your radio
senses that no signal has been received; a short triple-beep
will sound. If you move back into communication range,
as soon as the other station transmits, a short beep will
sound again.
