iv
Power Supply and Power Cord Use
WARNING
Do not hold the power plug with a wet hand.
Do not disconnect/connect the plug while your hands are wet. Failure to follow this
warning may cause an electric shock.
CAUTION
Plug in to a proper power source.
Use a proper wall outlet of the specified voltage. Use of an improper power source may
cause a fire or an electric leakage.
Do not install US40a where you need an extension cord. Use of a cord that does not
meet the power specifications of your US40a may heat up the cord and cause a fire.
Do not connect exceeding number of power cords to a power outlet to prevent
excessive electrical load.
The electric current exceeding the rated flow overheats the outlet, which may cause a
fire.
Insert the power plug into the outlet as far as it goes.
Heat generation resulting from a halfway inserted power plug (imperfect contact) may
cause a fire. Heat will also be generated if water droplet is formed on dusty plug and
causes the short circuit. The heat may result in fire.
Use the authorized power cord only.
Use only the power cord that comes with your US40a. Use of an unauthorized power
cord may cause a fire when the electric current exceeds the rated flow.
Also, observe the following to prevent an electric shock or fire caused by a damaged
cord.
■
Do not stretch the power cord.

Do not use any damaged power cord. (Replace a damaged power cord with a new
one of the same specifications. Ask your service representative for replacement.)
Do not use the attached power cord for any other devices or usage.
The power cord that comes with your US40a is designed aiming to connect with this
US40a, and its safety has been tested. Do not use the attached power cord for any
other purpose. Doing so may cause a fire or an electric shock.
Do not pull the cord to disconnect the power cord.
Hold the connector of the power cord and pull it straight. Pulling the cord or applying
excess force to the connector may cause a damage to the cable, resulting in a fire or
an electric shock.
