and Silence mode starts if the amount of light sensed is below the standard value
for
more than 1 minute.
(The mode does not start for initial 240 minutes to prevent down of cooling
performance.)

Control of Silence mode : operation mode when the optical sensor feels that it is
night
Normal control : daytime operation mode
(Refrigerator noise is relatively low at daytime.)
Load control : operation mode when inside temperature goes up due to an
increase of load (foods) or frequent door openings.
