[Circuitry Access] 

 
 
 
 

Do not

 remove covers, panels, casing, or access circuitry with power applied to the 

unit! Turn power off and disconnect power cord prior to removal. Internal servicing / 
adjustment of unit should only be performed by qualified personnel. 

 
 
 
 

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. 

[Rubber Feet] 

 
 
 
 

If this product has come with rubber feet attached by screws, do not insert the 
screws again without rubber feet after removing the rubber feet and screws. It may 
cause damage to the internal circuits or components of the unit. To install the rubber 
feet again to the unit, do not use other than the supplied rubber feet and screws.
