Voice Activated Audionic Earphone

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

PREPARATION 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.

VOX High/Low Positions — lets you adjust the microphone's sensitivity to your voice level.

Push-To-Talk (PTT) Button — lets you manually switch between transmitting and receiving.

Combination Mic/Earpiece — translates your voice into electrical signal for the transceiver during transmission, and acts as a normal earphone during reception.

Low-Power Circuitry — operates for more than

180 hours on one AAA alkaline battery (not supplied).

One Small and Two Large Replacement Earpiec-

es — provide a comfortable fit for any size ear opening.

Installing the Battery

You need one AAA battery (not supplied) to operate the earphone. For the longest battery life, we recommend a RadioShack alkaline battery. Follow these steps to install the battery.

1. Press down on the battery compartment cover and slide away from the clip.

2. Install the battery in the compartment as indicated by the polarity symbols (+ and –) marked inside.

3. Replace the cover.

Note: If you are using VOX and the transceiver does not switch to transmit when you begin speaking, replace the battery.

Using the Clip

You can use the clip to attach the earphone's control box to a pocket or belt.

Connecting to the Transceiver

Note: To avoid accidental transmission, set the function switch to OFF / PTT and turn off your transceiver before you connect the earphone to the transceiver.

Insert the earphone's 1 /

8

-inch speaker plug into the transceiver's earphone jack. Then insert the earphone's 3 /

32

-inch microphone plug into the transceiver's microphone jack.

1. Set the function switch to OFF / PTT .

2. Press PTT to transmit and release it to receive.

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.

PTT (Push-to-Talk Button) Operation

You can use the PTT button to manually switch between transmitting and receiving.

3. When you finish operation, turn off the transceiver.

VOX Operation

1. Set the function switch to VOX LO or HI .

2. When you start talking, the transceiver is automatically set to transmit. When you stop talking, the transceiver automatically switches to receive after about 1 second.

3. When you finish operation, turn off the transceiver first, then turn off the earphone by setting the function switch to OFF / PTT .

Volume Control

To adjust the level of receiving sound, rotate VOL .

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 PTT . When you release PTT , transmitting 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 PTT to transmit as described in “PTT

(Push-To-Talk Button) Operation.”

Setting VOX Sensitivity

If background noise or wind is strong, set the function switch to VOX LO to decrease the microphone's sensitivity. You might have to speak in a louderthan-normal voice to start transmitting.

To increase the microphone's sensitivity, set the function switch to VOX HI .

CARE

To enjoy your earphone for a long time:

• Keep the earphone dry. If it gets wet, wipe it dry immediately.

• Use and store the earphone only in normal temperature environments.

• Handle the earphone gently and carefully. Do not drop it.

• Keep the earphone away from dust and dirt.

• Wipe the earphone with a damp cloth occasionally to keep it looking new.

Modifying or tampering with the earphone’s internal components can cause a malfunction and might invalidate its warranty. If your earphone is not performing as it should, take it to your local RadioShack store for assistance.
