Improving range can be achieved by using a higher quality antenna, ensuring the radio is fully charged, and operating in an open area free from obstructions.

To adjust the squelch, turn the 'SQL' knob clockwise until background noise is eliminated. Turn it slightly counterclockwise if you wish to unmute weaker signals.
Regularly clean the exterior with a soft, dry cloth. Check antenna connections and ensure they are secure. Inspect the battery for any signs of damage or corrosion. Store the radio in a cool, dry place.
Check the microphone and speaker for obstructions or damage. Ensure the antenna is fully extended and securely connected. Adjust the volume and squelch settings. If issues persist, try switching channels to avoid interference.

Press and hold the 'FUNC' button followed by the 'LOCK' button. This will lock the keys and prevent accidental changes. Repeat the process to unlock.
