1) Turn off the the power.
Be sure to turn off the power before attempting to repair the
unit such as the disassembly of the unit.
2) Be careful of electric shock
When checking the circuit with the power connected in
unavoidable circumstances, take special care not to touch the
live parts. There is a danger of electric shock.
3) Use of appropriate parts
Be sure to use the genuine parts of the relevant model when
it is necessary to replace parts. (Replace parts instead of
repairing with regard to the malfunctioning of electric contact
areas. Never attempt to modify the unit. It is extremely dan-
gerous for the consumer to attempt to repair the unit on
his(her) own.)
4) Use of proper tools
Use appropriate tools for repair, and use measuring equip-
ment after accurate calibration. Using worn tools may result
in problems, including poor contact and poor connection.
5) Avoid damage to electric wire or electric cord.
Check the electric cord or electric wire for any damage during
repair.
Be sure to replace it if damaged.
6) Avoid intermediate connection of the electric cord.
Never attempt to make an intermediate connection by cutting
the middle area of the electric cord or make a connection to
the power receptacle as it is very dangerous, causing prob-
lems or fire.
7) Checking of insulation
Be sure to check the insulation resistance after completion of
the assembly work.
(Check whether the insulation resistance of the electric wire
and grounding terminal is over 30M
Ω
by using the insulation
resistance tester, and then connect the power source.)
8) Checking of grounding
Check the grounding condition, and perform repair if poorly
grounded.
9) Checking of installation condition
Check the installation condition of the unit, and perform
repair if there is any defective area.
If the unit remains in an unstable installing condition, install
it at a new site.
10) Be careful of children
As the repair of the unit involves a lot of dangerous elements,
do not allow children to approach nearby during repair work.
