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.
