5.4 Snooze Function and Backlight
When the alarm sounds, press the large SNOOZE/LIGHT button on the top of the clock.

6. Maintenance
6.1 Cleaning
To clean the clock, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the display or casing.
