Precautions
Important Safety Warnings
[Power]
Do not place or drop heavy or sharp-edged objects on power cord. A damaged cord
can cause fire or electrical shock hazards. Regularly check power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Circuitry Access]
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 power is disconnected. Capacitors associated with the power supply are
especially hazardous. Avoid contact with any capacitors.
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.
[Potential Hazards]
If abnormal smells or noises are noticed coming from the unit, turn power off
immediately and disconnect power cord to avoid potentially hazardous conditions. If
problems similar to above occur, contact authorized service representative before
attempting to again operate unit.
[Consumables]
The consumables used in unit must be replaced periodically. 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,
they should be replaced at an early date. For details on replacing the consumables,
contact your dealer.
