Operating Instructions
1. Sunrise Simulation
To activate the sunrise simulation, ensure an alarm is set. The light will gradually increase in brightness from 1% to 100% over a set period (e.g., 10-60 minutes before the alarm sounds), mimicking a natural dawn. This feature is designed to gently wake you up.
