Use the monitor function (accessible via FUNC menu) to temporarily disable squelch and listen to the current channel without transmitting, allowing you to hear very weak signals.

6. Maintenance

6.1 Cleaning

Wipe the device with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure all ports are closed when cleaning to prevent moisture ingress.

6.2 Battery Care

To prolong battery life, avoid fully discharging the battery frequently. Store the device and battery in a cool, dry place when not in use for extended periods. Recharge the battery regularly, even if not used, to maintain its capacity.

6.3 Antenna Care

Ensure the antenna is securely attached during use. Avoid bending or stressing the antenna excessively, as this can damage the connector or the antenna itself.

7. Troubleshooting

• No Power:
  Check if the battery is correctly installed and charged. Ensure the power/volume knob is turned sufficiently clockwise.
• Cannot Transmit or Receive:
  Verify the antenna is securely attached. Check the selected channel. Ensure the squelch level is not set too high, preventing reception of weaker signals. Confirm the battery has sufficient charge.
• Poor Audio Quality:
  Adjust the squelch (SQ/ASQ) settings. Ensure the NRC function is active (it is by default). Check for obstructions between communicating devices.
• Short Communication Range:
  Ensure the antenna is fully extended and unobstructed. Check for environmental factors like buildings, hills, or heavy foliage that can reduce range. Ensure both devices are on the same frequency and mode (AM/FM).
• Battery Not Charging:
  Verify the USB-C cable and adapter are properly connected. Ensure the power source is active. Check for any damage to the cable or charging port.
