5. Operating Instructions
5.1 Power On/Off and Volume Adjustment
Rotate the Volume/Power Knob (3) clockwise to turn on the radio. Continue rotating clockwise to increase the volume. Rotate counter-clockwise to decrease the volume and turn off the radio.
5.2 Channel Selection
Rotate the Channel Knob (2) to select one of the 16 available communication channels. Ensure all radios in your group are set to the same channel for communication.
5.3 Transmitting and Receiving
- To Transmit: Press and hold the PTT Button (5). Speak clearly into the Microphone (9). The LED indicator will typically glow red during transmission.
- To Receive: Release the PTT button. The radio will automatically switch to receive mode. The LED indicator will typically glow green when receiving a signal.
5.4 AI Noise Reduction
The walkie-talkie features an AI NC chip to filter background noise. This function is typically active by default or can be toggled using the Noise Reduction/VOX Button (6). When active, it ensures crystal clear audio transmission in noisy environments like factories or KTVs.
5.5 VOX Function (Voice Operated Exchange)
The VOX function allows you to transmit without pressing the PTT button. When VOX is enabled, the radio will automatically transmit when it detects your voice. This can be activated or deactivated by pressing the Noise Reduction/VOX Button (6). This feature is useful when your hands are occupied.
5.6 One-to-Many Call
The radio supports one-to-many communication on the same channel. This allows multiple users in a team or department to communicate simultaneously, making it efficient for large group coordination.

8. Troubleshooting
- No Power:
- Check if the battery is properly installed and charged.
- Ensure the Volume/Power knob is turned clockwise to the 'on' position.
- Cannot Communicate with Other Radios:
- Verify that all radios are on the same channel.
- Ensure radios are within the effective communication range (1.5km-3km, depending on terrain and obstacles).
- Check if batteries are sufficiently charged.
- Poor Audio Quality / Static:
- Move to an open area to reduce interference.
- Ensure the antenna is securely attached.
- Adjust the volume.
- Confirm Noise Reduction is active in very noisy environments.
- Radio Not Charging:

- Ensure the radio is correctly seated in the desktop charger or the Type-C cable is properly connected.
- Verify the power source is active.
9. User Tips
- Optimal Range: For best communication range, use the radios in open areas with minimal obstructions. Buildings, hills, and dense foliage can significantly reduce range.
- Battery Life: To maximize battery life, consider using the radio's power save mode if available, and turn off the radio when not in active use.
- Clear Communication: Speak clearly and at a normal volume into the microphone. Avoid shouting.
- VOX Sensitivity: If using VOX, you may need to adjust its sensitivity to prevent accidental transmissions or missed voice activations.
- Channel Etiquette: In shared environments, be mindful of other users and avoid unnecessary chatter on busy channels.
