Precautions
Important Safety Warnings
[Power]
Stop
Do not place or drop heavy or sharp-edged objects on the power cord. A damaged
cord can cause fire or electrical shock hazards. Regularly check the power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Circuitry Access]
Stop
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even after
the power has been disconnected. Capacitors associated with the power supply are
especially hazardous.
Hazard
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating the unit with circuitry exposed could result in electric shock / fire hazards or
a unit malfunction.
[Potential Hazards]
Caution
If abnormal odors or noises are noticed coming from the unit, immediately turn the
power off and disconnect the power cord to avoid potentially hazardous conditions. If
problems similar to the above occur, contact an authorized service representative
before attempting to operate the unit again.
[Consumables]
Caution
Consumable items that are used in the unit must be periodically replaced. For further
details on which parts are consumables and when they should be replaced, refer to the
specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
such items should be replaced at an early date. For details on replacing consumable
items, contact your dealer.
