Never attempt to disassemble, repair, or alter the product on any occasion except as described
in this document. Failure to follow this warning may cause not only malfunction of the product
but also an electric shock or fire.

The product contains the lithium battery. Do not remove the battery. Placing a battery close to
a fire or in the water may cause an explosion.
When the product does not operate appropriately due to the dead battery, contact the store
you purchased the product or your maintenance service company. Do not attempt to
disassemble the product to replace or recharge the battery by yourself.
Disconnect the power plug before working with the product.
Be sure to power off the product and disconnect the power plug from a power outlet before
installing/removing the product. Touching any internal device of the product with its power cord
connected to a power source may cause an electric shock even if the product is off-powered.
In addition, do not install or remove the product while your hands are wet. Doing so may cause
an electric shock as well as malfunctions of the product.
Occasionally disconnect the power plug from the outlet and clean the plug with a dry cloth.
Heat will be generated if condensation is formed on a dusty plug, which may cause a fire.

Immediately after the product is powered off, its internal components are very hot. Leave the
product until its internal components fully cool down before installing/removing.
Connect the components firmly.
Be sure to secure the power cord, interface cables, cooling fans, and power supply unit in
place. Incomplete installation causes a loose connection, resulting in smoke or fire
Pay attention to electric shock
The cooling fans and power supply unit (only when two units are installed) support hot
swapping. If replacing a component when the electrical current is being supplied, use extreme
caution not to get electric shock by touching terminal parts of the internal components.
