SAFETY PRECAUTIONS
1. The d es ign of th is prod uct c on ta ins sp eci al har d wa re, ma ny

2. Alte r ati on s of the design or ci r cui try of t he prod ucts sh ould not be
made. Any design alterations or additions will void the
manufact ur er 's warrant y and will f urth er r eliev e t he ma nu factu r er

cause shock, fire, or other hazards .
4. Don't shor t between the LIVE side ground and ISOLATED
(NE UTRAL) side ground or EARTH side ground when
repairing.
Some model's power circuit is partly different in the GND. The
diff er enc e of the GN D is sh own by the LI VE si de G ND, the
ISO LATED(NEUT RAL) side GND a nd EA RTH si de GND. Don' t

same time.
If above note will not be kept, a fuse or any parts will be broken.
5. If any repair has been made to the chassis, it is recommended
