30, 60, 90 min Auto-off Timer & Memory Function
This sound machine for sleeping has a 30, 60, or 90 min auto-off timer. Choose your desired sound, adjust the volume, and set the timer to your preference. The sound machine will then play non-looping soothing sounds.
The memory function allows you to quickly play your favorite sound each time you use it, it would also remember the most recent volume and timer setting.
