4.2. Channel Selection

Rotate the Channel Switch knob (B) to select one of the 16 available channels. Ensure all radios you wish to communicate with are set to the same channel.

4.3. Transmitting and Receiving

1. To transmit, press and hold the PTT (Push-To-Talk) button (D). Speak clearly into the microphone, holding the radio approximately 2-5 cm from your mouth. The LED indicator light (A) will turn red.
2. Release the PTT button to stop transmitting and return to receive mode. The LED indicator light will turn green when receiving a signal.

4.4. Monitor Function

Press the Monitor button (E) to temporarily open the squelch and listen for weak signals or to check if a channel is clear before transmitting. Release the button to re-engage squelch.

4.5. Flashlight Function

Press the Flashlight button (F) to turn the built-in LED torch on or off. This feature is useful in low-light environments.

5. VOX Function (Voice Operated Exchange)

The VOX function allows for hands-free communication by automatically transmitting when it detects your voice, without needing to press the PTT button.

5.1. Activating/Deactivating VOX

Follow these steps to enable or disable the VOX function:

1. Ensure the radio is turned on.
2. Rotate the Channel Selector knob to Channel 1 (VOX function can be activated on channels 1-5).
3. Turn the radio off.
4. Press and hold both the PTT button and the Monitor button simultaneously.
5. While holding both buttons, turn the Power Switch/Volume Control knob clockwise to turn the radio on.
6. Release the PTT and Monitor buttons once the radio powers on.

To verify activation, speak close to the walkie-talkie. If the LED indicator light turns red, the VOX function is active. If not, repeat the steps, trying channels 1 through 5.

5.2. VOX Sensitivity

Due to potential surrounding noise, the VOX function's sensitivity is optimized to prevent unwanted transmissions. For reliable voice detection, it is recommended to speak close to the walkie-talkie or connected earpiece/headset when VOX is active.
