Epson MR Series Technical Reference Manual page 8

Do not charge the internal lithium battery or leave it in a hot place such as near a fire or
on a heater because it could overheat and ignite.
When you dispose of the internal lithium battery, insulate it by wrapping the terminals
with tape. Mixing the battery with other metals or batteries may lead to fire, heat, or
explosion.
Be sure your power cable meets the relevant safety standards and includes a power
system ground terminal (PE terminal).
There is a ventilation opening on the right side; do not place any object in front of it. If
you set this product upright, be sure the ventilation opening is on the top. Do not place
any object on top of the ventilation opening.
Handle the power cable with care. Improper handling may lead to fire or shock.
Do not modify or attempt to repair the cable.
Do not place any object on top of the cable.
Avoid excessive bending, twisting, and pulling of the cable.
Do not place the cable near heating equipment.
Check that the plug is clean before plugging it in.
Be sure to push the prongs all the way in.
Do not use a damaged cable.
Regularly remove the power plug from the outlet and clean the base of the prongs and
between the prongs. If you leave the power plug in the outlet for a long time, dust may
collect on the base of the prongs, causing a short and fire.
CAUTION:
When replacing the battery, use only an equivalent type battery recommended by the
manufacturer. If your system has a module containing a lithium battery, replace it only
with the same module type made by the same manufacturer. The battery contains
lithium and can explode if not properly used, handled, or disposed of.
Do not connect cables other than those specified in this manual. Doing so may result in
fire or improper operation.
Do not connect the unit to electrical outlets that are close to devices that generate
voltage fluctuations or electrical noise. In particular, stay clear of devices that use large
electric motors.
Always connect the power cable to the IM-800 before plugging it into the wall outlet.
Be sure to push the plug of the power cable all the way into the AC inlet of this product.
The plug should make contact with the back of the inlet.
When disconnecting the power cable, hold the plug firmly. Do not tug on the cord itself.
