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
receiving (see "PTT (Push-to-Talk) Button Operation"), or use VOX to automatically transmit when
you talk, then receive when you stop talking (see
"VOX Operation").
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.

Notes:
• Because the earphone quickly switches the
transceiver to transmit as soon as you start talking, the receiving party might not hear the first
word you say. To ensure your entire message is
received, extend or repeat the first word of each
transmission.
• To transmit continuously during VOX operation,
even if you stop talking for a few seconds, hold
down
. When you release
PTT
, transmitting
PTT
stops after about 1 second of silence.
• Be sure to set the transceiver’s volume control
between the middle point and the maximum
point. The VOX function might not operate if you
set the transceiver’s volume control to a lower
point.
• If your transceiver receives noise or cross talk,
the VOX function might operate. In such a case,
press
to transmit as described in “PTT

(Push-To-Talk Button) Operation.”
