Caution on condensation
Condensation (of dew) may occur inside the unit when there is
a great difference in temperature between this unit and the out-
side.
This unit may not function properly if condensation occurs. In
this case, leave the unit for a few hours, and restart the opera-
tion after the condensation has dried up.
Be specially cautious against condensation in a fol-
lowing circumstances:
When this unit is carried from one place to another across a large
difference in temperature, when the humidity in the room where
this unit is installed increases, etc.
Stored contents which are
cleared in at least a week after
power plug is unplugged from
power outlet.
