Auto

Note

• AUTO mode is only available for HU4903.

The automatic mode uses the digital sensor

to constantly monitor the air quality. It turns

your humidier on and off whenever needed

to ensure the humidity level is constantly at

the right level. The default humidity level of

the automatic mode is set at 50%, but you can

change it to your desired humidity level for the

automatic mode. Next time when you switch

on the humidier, it will remember your last

set humidity level, unless you have unplugged

the wall socket. In this case the default humidity

level of 50% is set again.
