* Use to adapt the plug on the
power cord to the shape of the
wall outlet.
(Accessory only for regions
where use is necessary.)
The marking is located on the rear panel and says that
the component uses laser beams that have been classified as Class 1. It means that the unit is utilizing laser
beams that are of a weaker class. There is no danger of
hazardous radiation outside the unit.

Operation to reset
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, execute the
following procedure to reset the microprocessor and return it to
normal condition.
÷Please note that resetting the microprocessor clears the
contents stored in, it returns the microprocessor to the condition when it left the factory.
1 In
POWER ON
condition, keep the
DISC 3
key and the

(Skip) key pressed at the same time.
2 When both keys are pressed, the region code of the unit, the
software version, etc. will be displayed on the display. (When
nothing is done, the display of this information continues.)
Example: 71 . 16 . 06:14

Note related to transportation and movement
Before transporting or moving this unit, carry out the following operations.
1. Set the POWER key to ON without loading a disc.
2. Wait a few seconds and verify that the display shown
appears.
3. Set the POWER key to OFF.
Beware of condensation
When the difference between the internal temperature of the unit
and external atmosphere is large, dew (mist) may be produced on
the internal parts of the unit. In such a case, turn the unit ON and
leave it for a few hours until the condensation has dried up.
Be especially careful in the following conditions:
When the unit is brought into a place where there is a large difference in temperature between the previous location, when the
humidity of the listening room is high, etc.
