Voice Activated Audionic Earphone

OWNER’S MANUAL — Please read before using this equipment.

FEATURES

Your RadioShack Voice-Activated Audionic Ear­phone makes it easier and safer to use your hand­held transceiver. The ultra-light weight speaker/
microphone combined with voice-activation makes
hands-free communications a breeze. You can con­tinue your activities without interrupting your com­munication. Just connect the earphone’s plugs to
the jacks on your transceiver.

You can use this earphone with many of the
RadioShack handheld amateur radio, business
band, Family Radio Service, citizen's band, and
GMRS tranceivers that have external microphone
and speaker jacks.

The earphone is also compatible with Icom, Stan­dard, Yaesu, and Alinco transceivers.

The earphone’s features include:
Voice Activation Control (VOX) — you can set the

earphone to automatically activate the transceiver
so you transmit only when you speak.

OPERATION

You can manually switch between transmitting and

Before you begin operation, set the transceiver's vol­ume control to the center position, squelch control to
the on position, and turn on the transceiver.

Caution: Never position the earphone's cord or con­trol box near the transceiver's antenna. If the cord or
the control box is too close to the antenna, the range
might be reduced or the control box might not cor­rectly switch the transceiver between transmit and
receive.
