To prevent the possibility of electrical shock, do not perform maintenance, repair, or

Shut down your equipment immediately if it produces smoke, a strange odor, or
unusual noise. Continued use may lead to fire or electric shock. Immediately unplug
the equipment.
Only disassemble this product as described in this manual. Do not make
modifications to the unit. Tampering with this product may result in injury, fire, or
electric shock.
Be sure to use the specified power source. Connection to an improper power source

Never insert or disconnect the power plug with wet hands. Doing so may result in
severe shock.
CAUTION:
Parts on the circuit board may become hot during operation. Therefore, wait
approximately 10 minutes after turning the power off before touching them.
To avoid injury, take care not to insert fingers or any part of the hand in the paper roll
