Night mode
The purier works in harmony with its
surroundings. The purier automatically switches
to night mode in 3 minutes when the room in
which it is operating becomes dark. All the lights
on the control panel slowly go out. You can
touch any buttons on the control panel during
this period, and the lights go back on. However,
they will go out again in 5 seconds if the purier
is in idle.
If the room becomes bright again for 5
minutes or longer, the purier resumes normal
operation.
