Troubleshooting and error codes
| Problem | Solution |
|---|---|
| The appliance does not work. | Check plug insertion, power failure, or damaged mains cord. |
| The appliance becomes hot during use. | Normal operation; it's heated by the lamp. If it overheats and switches off, remove cause of overheating, unplug, cool, and plug back in. |
| The appliance does not respond when I try to set different functions. | Press the Reset button or unplug/reinsert the plug. |
| The light does not go on when the alarm goes off. | Light intensity level may be set too low. Increase it using the light intensity wheel. |
| The lamp does not work. | Check if alarm function was switched off, lamp is defective, or not screwed in. |
| I cannot switch on the lamp again immediately after I switched it off. | Wait 3 seconds for the lamp to dim. The C button is inactive during this time. |
| I do not hear a sound when the alarm goes off. | Sound level may be set too low. Increase it using the volume control wheel. Alarm function may have been switched off. |
| The radio does not work. | If radio was selected as alarm sound, it may be defective. Check by pressing the radio button after switching off the alarm. Contact Consumer Care if it still doesn't work. |
| The radio produces a crackling sound. | External antenna may not be properly positioned, or broadcast signal may be weak. Adjust antenna or search for the correct signal. |
| The alarm went off yesterday, but it did not go off today. | Alarm function may have been switched off. Set alarm for next day and ensure sound/light are not manually switched off. Sound/light levels might be too low. Check for power failure impacting backup system; reset clock and alarm time if needed. |
| The light wakes me too early/too late. | Light intensity level may be inappropriate. Adjust higher or lower. If intensity 20 is not enough, move appliance closer. Appliance may be positioned too low or too far away. |
| The SNOOZE button does not function. | Snooze function is only available within 15 minutes after the alarm starts. After that, the button only functions as SCREEN BRIGHTNESS CONTROL. |
