Backup Battery Replacement:
If the clock loses time or settings during a power outage despite the backup battery being installed, it may need replacement. Open the battery compartment on the back, remove the old CR2032 battery, and insert a new one with the positive (+) side facing up. Dispose of the old battery responsibly.
Storage:
If storing the clock for an extended period, unplug it from the power source and remove the backup battery to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or not lighting up. | Power adapter not connected or faulty; power outage. | Ensure the power adapter is securely plugged into the clock and a working outlet. Check the power source. |
| Clock loses time or settings after power disconnection. | Backup battery plastic tab not removed or battery is depleted. | Remove the plastic tab from the CR2032 backup battery. If already removed, replace the CR2032 battery. |
| Alarm does not sound. | Alarm not set correctly; alarm volume too low; alarm turned off. | Verify alarm time and mode. Ensure alarm is activated (solid icon). Check if there's a volume setting (if applicable, though not explicitly mentioned for this model, it's a common troubleshooting step). |
| Display is too bright or too dim. | Brightness level needs adjustment. | Press the SNOOZE/DIMMER button to cycle through the 5 brightness levels. |
| Temperature reading seems inaccurate. | Clock placed near a heat source or vent. | Relocate the clock to an area with stable ambient temperature. |
