Operation
Time Synchronization
After successful Bluetooth pairing, the clock will automatically set its time and date based on your smartphone. It is designed to self-adjust for Daylight Saving Time (DST) changes if enabled in the app settings.
Setting Alarms
Alarms are primarily set and managed through the Marathon clock application. Open the app, navigate to the alarm settings, and follow the prompts to set desired alarm times, days, and tones.

Using the Snooze Function
When an alarm sounds, press the Snooze button on the rear panel to temporarily silence the alarm. The alarm will sound again after a preset snooze interval (typically 5-10 minutes, configurable via the app).

Maintenance
- Cleaning: Wipe the clock's surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents, which may damage the display or casing.
- Battery Replacement: Replace batteries when the display dims or the clock stops functioning. Always replace all batteries at the same time with new ones of the same type. Dispose of old batteries responsibly.
- Storage: If storing the clock for an extended period, remove the batteries to prevent leakage and damage.
Troubleshooting
| Problem | Solution |
|---|---|
| Clock does not power on or display is dim. | Check battery installation. Ensure batteries are new and inserted with correct polarity. Replace batteries if necessary. |
| Clock does not synchronize with smartphone. | Ensure Bluetooth is enabled on your smartphone and the clock is in pairing mode. Make sure the clock is within Bluetooth range. Try restarting the app or your phone. If issues persist, try unpairing and re-pairing the device. |
| Time is incorrect or does not adjust for DST. | Verify that the clock is successfully paired with the app. Check app settings for time zone and Daylight Saving Time preferences. Ensure your phone's time is correct. |
| Poor battery life. | Ensure you are using high-quality alkaline batteries. Frequent use of certain features or constant Bluetooth connection attempts may consume more power. |
| Display is difficult to read from certain angles. | This may be a characteristic of the LCD display. Try adjusting the viewing angle or lighting conditions in the room. |
| Cannot connect multiple devices to the clock. | The clock is designed to pair with one controlling device at a time. To connect a different device, the current connection must be disconnected or forgotten. |
