Maintenance

Cleaning

Wipe the radio's exterior with a soft, dry cloth.
Do not use abrasive cleaners, solvents, or strong chemicals, as these may damage the finish.
Avoid exposing the radio to excessive moisture.

Battery Care

To prolong battery life, avoid fully discharging the battery frequently.
If storing the radio for an extended period, charge it to approximately 50% and recharge every few months.
Use only the supplied USB charging cable.

Troubleshooting

Problem	Possible Cause / Solution
Radio does not power on.	Ensure the battery is charged. Connect the radio to a power source using the USB cable. Confirm you are performing a long press on the POWER/MUTE button to power on, not a short press which may activate sleep mode. Check if the HOLD switch is in the 'Unlock' position.
Poor reception or static.	Ensure headphones are fully plugged into the headphone jack, as they act as the external antenna. Try repositioning the radio or moving to an area with better signal. For AM, the internal ferrite bar antenna is directional; try rotating the radio for better reception.
Buttons are unresponsive.	Check if the HOLD switch is in the 'Lock' position. Slide it to 'Unlock'. If the radio is frozen, try powering it off and on again (long press POWER/MUTE).
Battery drains quickly.	Ensure the radio is fully powered off (long press POWER/MUTE) when not in use, not just in sleep mode. Battery performance can degrade over time with repeated charge cycles.
