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.

Note related to transportation and movement
Before transporting or moving this unit, carry out the
following operations.
1Remove the disc from the unit.
2Press the 6key.
3Wait a few seconds and turn the unit OFF.
Operation to reset
The microcomputer 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
microcomputer and return it to normal condition.
÷Please note that resetting the microcomputer clears the
contents stored in and returns and to condition when it left
the factory.
Set the POWER switch to ON (set to Standby mode).
Then press the ¢key, 4key and STOP key in this
order.
