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
o 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.
