5.3. Storage
Store the timer in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the battery to prevent leakage.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer does not turn on. | Battery is dead or incorrectly installed. | Replace the battery with a new CR2032, ensuring correct polarity. |
| Display is dim or flickering. | Low battery. | Replace the battery. |
| Alarm is too loud. | Buzzer volume is fixed. | The buzzer volume is approximately 65dB at 15cm and cannot be adjusted. Consider using the LED alarm only if available (not a direct feature on this model, but a general suggestion). |
| Timer does not respond to button presses. | Temporary software glitch or low battery. | Remove and reinsert the battery. If the issue persists, replace the battery. |
| Sequential timers do not advance. | Incorrect setting or timer paused. | Ensure all steps are correctly saved using the Memory button. Check if the timer is paused. |
