3. Setup

Follow these steps to set up your Retevis RE3120 earpiece:

1. Connect the Earpiece: Locate the 2-pin connector on your earpiece. Align the pins with the corresponding ports on your compatible walkie-talkie (e.g., Retevis, Baofeng, Kenwood models). Gently push the connector firmly into place until it is fully seated.
2. Wear the Earpiece: Place the C-type earhook over your ear. The earhook is designed to fit comfortably around the earlobe. Adjust the earhook for a secure and comfortable fit. The earhook can rotate 360 degrees to be worn on either the left or right ear.

4. Operating Instructions

Operating the Retevis RE3120 earpiece is straightforward:

1. Receiving Audio: Once connected, audio from your walkie-talkie will be transmitted directly to the earpiece, allowing for private listening.
2. Transmitting Audio (PTT): To speak, press and hold the Push-to-Talk (PTT) button located on the remote microphone unit. Speak clearly into the microphone. Release the PTT button when you have finished speaking to return to receive mode. This eliminates the need to hold your walkie-talkie during communication.
3. Using the Rotatable Clip: The earpiece cable features a rotatable clip. You can attach this clip to your clothing (e.g., collar, lapel) or any convenient location to secure the cable and position the microphone closer to your mouth for optimal voice transmission.

5. Maintenance

Proper care will extend the lifespan of your earpiece:

• Cleaning: Use a soft, dry cloth to wipe down the earpiece and cable. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the microphone or connector.
• Storage: When not in use, store the earpiece in a clean, dry place away from direct sunlight and extreme temperatures. Avoid tangling the cable to prevent damage.
• Handling: Do not pull the cable forcefully when disconnecting from the walkie-talkie. Always grasp the connector itself.
