5. Maintenance
- Cleaning: Wipe the stopwatch with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store in a cool, dry place away from direct sunlight when not in use for extended periods.
- Water Resistance: The stopwatch is water-resistant, but not waterproof. Avoid submerging it in water or exposing it to high-pressure water jets.
- Battery: The solar panel charges the internal battery. Ensure regular exposure to light to maintain optimal battery life. No user-replaceable battery is required under normal operation.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Insufficient light exposure for solar charging. | Expose the solar panel to bright light for several hours. |
| Incorrect time/date. | Time/date not set correctly or reset after power loss. | Refer to Section 3.2 "Setting Time and Date" to adjust. |
| Stopwatch not responding. | Temporary software glitch. | Attempt a soft reset by pressing all buttons simultaneously for a few seconds (if applicable, consult specific model instructions if available). If not, allow battery to fully drain and recharge. |
| Inaccurate environmental readings. | Sensor obstruction or not enough time for stabilization. | Ensure sensors are clean and unobstructed. Allow 5-10 minutes for readings to stabilize after moving to a new environment. |
