Note related to transportation and movement
Condensation (of dew) may occur inside the unit when there is a great
difference in temperature between this unit and the outside. This unit
may not function properly if condensation occurs. In this case, leave
the unit for a few hours and restart the operation after the condensa-
tion has dried up.
Be specially cautious against condensation in the following circum-
stances:
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.

"Dolby" and the double-D symbol are trademarks of Dolby
Laboratories.
The microprocessor may fall into malfunction (impossibility to operate erroneous display, etc.) when the power cord is
unplugged while power is ON or due to an external factor.
In this case, switch off the power, wait for several seconds, and then switch the power on again.
