White Noise - Button Mulfunction | WN07

Phenomenon:

Buttons, Knobs, or Controls Not Responding

 

Applicable Scope:

White Noise WN07

Solution:

1. Return to the clock screen and test only one control at a time.
2. Briefly press the Sound, Light, Alarm, or Timer control shown by its icon.
3. For a rotary control, turn it one step and press it once to confirm.
4. If your version uses different icon positions, follow the icon printed on that unit rather than another version’s layout.
5. Turn off or disconnect the device and wipe the affected control area with a clean, dry cloth.
6. Check whether the control is stuck, sunken, loose, or visibly damaged, then test the same control once.
7. Disconnect power for 30 seconds, then reconnect it.
8. After it returns to normal operation, test the same control again.
