Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock display is blank. | No power, AC adapter unplugged, or power outage with no battery backup. | Ensure AC adapter is securely plugged into the clock and a working wall outlet. Install a fresh 9V battery for backup. |
| Alarm does not sound/vibrate/flash. | Alarm not set, alarm mode switch set to OFF, or volume too low. | Verify alarm time is set correctly. Check that the ALARM MODE switch is set to a desired alert option (e.g., ALL IN, SOUND, SHAKER). Increase volume if using audible alarm. Ensure shaker is properly connected. |
| Display is too bright/dim. | Dimmer switch setting. | Adjust the DIMMER switch on the front panel to your preferred brightness level. Note: The display has specific brightness levels, not a continuous dimming range. |
| Telephone alert not working. | Telephone line not connected, or alarm mode not set to include flash/sound/shaker. | Ensure telephone line is securely connected to the clock and wall jack. Check that the ALARM MODE switch is set to an option that includes a visual, audible, or vibratory alert. |
| Time is incorrect after power outage. | No 9V battery installed, or battery is depleted. | Install a fresh 9V battery for battery backup. Reset the time if necessary. |
