4.2 Battery Life
The watch is powered by a product-specific battery designed to last approximately 7 years under normal use. When the display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should be performed by a qualified technician.
4.3 Cleaning
Wipe the watch with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent, then wipe dry. Avoid using volatile agents like thinner or benzine, as they may damage the resin components.
5. Troubleshooting
- Incorrect Time/Date: Ensure the time and date are set correctly as per Section 2.1. If the issue persists after resetting, the battery may be low.
- Display is Dim or Blank: This typically indicates a low battery. Replace the battery promptly.
- Buttons Not Responding: Check if the watch is wet. If so, dry it thoroughly. If the issue continues, the watch may require servicing.
- Alarm Not Sounding: Verify that the alarm is activated in Alarm Mode (Section 3.2). Check the volume settings if applicable (though this model typically has a fixed alarm tone).
