CAUTION
1.Precautions for Service Jobs
A toothed washer and spring washer, if used originally,
must be reinstalled. Omitting them may result in contact
failure which could cause an electric shock or fire.
When reassembling parts, make sure that the correct
screws (size, type) are used in the correct places. Using the
wrong screw could lead to stripped threads, poorly secured
parts, poor insulating or grounding, and result in a
malfunction, electric shock or injury.
Take great care to avoid personal injury from possible burrs
and sharp edges on the parts, frames and chassis of the
product.
When moving the product or removing an option, use care
not to injure your back or allow your hands to be caught in
mechanisms.
2.Precautions for Servicing with Covers and Parts Removed
Wherever feasible, keep all parts and covers mounted when
energizing the product.
If energizing the product with a cover removed is absolutely
unavoidable, do not touch any exposed live parts and use
care not to allow your clothing to be caught in the moving
parts. Never leave a product in this condition unattended.
Never place disassembled parts or a container of liquid on
the product. Parts falling into, or the liquid spilling inside, the
mechanism could result in an electric shock or fire.
Never use a flammable spray near the product. This could
result in a fire.
Make sure the power cord is unplugged before removing or
installing circuit boards or plugging in or unplugging
connectors.
Always use the interlock switch actuating jig to actuate an
interlock switch when a cover is opened or removed. The
use of folded paper or some other object may damage the
interlock switch mechanism, possibly resulting in an electric
shock, injury or blindness.

3.Precautions for the Working Environment
The product must be placed on a flat, level surface that is
stable and secure.
Never place this product or its parts on an unsteady or tilting
workbench when servicing.
Provide good ventilation at regular intervals if a service job
must be done in a confined space for a long period of time.
Avoid dusty locations and places exposed to oil or steam.
Avoid working positions that may block the ventilation ports
of the product.
4.Precautions for Handling Batteries
(Lithium, Nickel-Cadmium, etc.)
Replace a rundown battery with the same type as specified
in the manufacturer's parts manual.
Before installing a new battery, make sure of the correct
polarity of the installation or the battery could burst.
Dispose of used batteries according to the local regulations.
Never dispose of them at the user's premises or attempt to
try to discharge one.
