PREFACE
PREFACE
Most accidents occur due to the failure to observe basic safety rules and precautions. To
prevent accidents, it is important to prevent their causes. Service persons of this product
(hereafter referred to as SP) must therefore attend servicing skill seminars before carrying
out servicing and read this manual thoroughly to fully understand safety precautions,
appropriate servicing procedures and methods.
Failure to do so will result in unexpected accidents.
Since it is not possible to list all imaginable dangers which may occur during servicing, the
SP must carry out servicing with extreme care to ensure safety at all times, in addition to
observing the precautions labeled on the product and indicated in this manual.

WARNING
CAUTION
Ignoring this mark could result in the possibility of serious
injury or even death.
Ignoring this mark could result in the possibility of injury
or physical damage.
WARNING
Use only the power supply voltage specified on the main nameplate.
Using other voltages could result in a fire or an electrical shock.
Make sure that the combined power consumption of the appliances to be
connected does not exceed the capacity rating of the power outlets or plug
receptacles.
Exceeding the capacity rating could cause the power outlets, plug receptacles, or
power extension cords to overheat and catch a fire.
2.1 Power Supply
Make sure the power supply used is always within the following range.
Power supply : AC 120 V 60 Hz (USA model), AC 220 to 240 V 50/60 Hz (UK model)
Rated current (Rated power) : 2 to 1 A (140 W)

PREFACE
WARNING
Keep this unit and the power cord away from heaters and heater vents.
Excessive heat could melt the cover or power cord covering, and result in a fire or
an electrical shock.
Do not place metal objects or vessels containing liquids on top of the unit.
The entry of any metal object or liquid could result in a fire or an electrical shock.
Do not insert any metal or easily-combustible object inside this unit.
This could result in a fire or an electrical shock.
CAUTION
Do not install the unit in the following environment.
Otherwise it may cause fire or an electric shock.
where the temperature is high
where the unit will be subject to direct sunlight
near fire
where it is considerably dusty
where there is considerable vibration
where there is considerable air-borne salt
where there are harmful chemicals
Do not install this unit in a location where there is excessive humidity or where
contact with water is possible.
Poor choice of location could result in deterioration of the insulation, a fire or an
electrical shock.
Do not install the unit near devices which emit strong magnetic force and in
magnetic fields.
Otherwise incorrect operations and malfunctions may occur.
Install this unit on a level, stable stand or floor, with sufficient space around it.
Failure to do so could result in the unit overturning and causing injury.
2.2 Operating Environment
Operate this unit in the following environment.
where the temperature range is between 5 and 35°C (–10 to +50°C in storage)
where the humidity range is between 20 and 80% RH (10 to 90% RH in storage, however
no condensation)
CAUTION
Do not place anything around the socket-outlet to ensure that the power plug
can be disconnected anytime.
If the power plug cannot be disconnected immediately when product failure
occurs, it could result in fire or an electric shock.
This unit shall be installed near the socket-outlet where the plug on the power
supply cord is easily accessible.
If the power plug cannot be disconnected immediately when product failure
occurs, it could result in fire or an electric shock.

PREFACE
WARNING
Do not damage the power cord or power plug.
Do not scratch, alter, bend, twist, pull or place heavy objects on the power cord or
power plug.
This could result in damage, a fire or an electrical shock.
Do not handle the power plug with wet hands.
This could result in an electrical shock.
Do not use flammable sprays inside or near the unit (e.g. when cleaning the
unit).
Such flammable gas may ignite and cause a fire or combustion.
Take precautions against fire and ensure ventilation when using alcohol, and
store the alcohol in a safe place after use. Also note that use of other solvents can
damage the rubber rollers and resin inside the unit, resulting in malfunctions.
If any foreign object such as metal or liquid should enter this unit, immediately
turn the unit off at the power switch and disconnect the power plug from the
power outlet.
Failure to do so could result in a fire or an electrical shock.
Before cleaning this unit, turn the unit off at the power switch and disconnect
the power plug from the power outlet.
Accidental operation of the unit during cleaning could result in injury.
Before beginning servicing work, turn the unit off at the power switch and
disconnect the power plug from the power outlet.
Accidental operation of the unit during servicing could result in injury.
If removing covers to check operations, be very careful to ensure that hands and
clothing are not drawn into movable parts.
Remove any dust that accumulates on the power plug prongs and the surface
of the plug from which the prongs extend.
Accumulated dust could result in a fire.
Always grip the plug when disconnecting the power plug from the power outlet.
Forcibly pulling on the power cord could cause damage, resulting in a fire or an
electrical shock.
