Maintenance
Cleaning
Wipe the clock with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the finish or internal components.

Replace all three AA batteries when the clock's display dims, the alarm sound weakens, or the clock stops functioning. Always replace all batteries at the same time with new ones.
Troubleshooting
- Clock not working / Alarm not sounding:
Check if the batteries are inserted correctly and are not depleted. Ensure the alarm ON/OFF switch is in the "ON" position. - Alarm sound is too quiet or too loud:
Adjust the "VOL." dial on the back of the clock to your desired level. - Time is inaccurate:
Ensure the batteries are fresh. Quartz movements are generally accurate, but extreme conditions can affect performance.
