Precautions for Safety
○Before using this equipment, be sure to read through the "Precautions for Safety" and operation manual
to ensure its correct operation.
○After reading these documents, keep them handy so that anyone can read them at any time.
1. Restrictions on Using Environment
• Be careful in that no water mixes in this equipment to be free from getting wet. Otherwise, it can
cause a fire, electric shock or fault.
• When this equipment is used in a dampen place, be sure to connect it to the earth.
2. Restrictions on Using Conditions
• Do not use this equipment beyond the specified supply voltage. Otherwise, it causes a fire, electric
shock or fault.
• When this equipment is connected to a commercial power supply, connect it directly to an exclusive
plug socket without fail. Do not use any extension cord, since it fears to cause a risk of heating or
igniting.
3 Setup and Installation
3.1 Cautions to Personnel who Sets Up and Installs this Equipment
• Do not put many loads on one electrical outlet to avoid causing a fire or heating.
• Be sure to insert a power plug into its socket surely. If a metal piece or the like touches to the
blade of the power plug socket, it causes a fire or electric shock.
• When the equipment is installed on a product with caster (dolley, etc.), be sure to lock the caster.
If the product moves or falls down, it can cause a physical injury.
3.2 Restrictions or Prohibitions in Installing Environment and Conditions
• Do not place this equipment at a place where is fairly damp or dusty. Otherwise, it can cause an
electric shock or fault.
• Do not put this equipment in a unstable place such as a shaky table or inclined location to avoid it
falling down or bringing down. If does, it can cause aphysical injury.
• Do not put this equipment at a place where is subject to vibration or shock. If it falls down or
brings down, it can cause a physical injury.
• Do not insert or drop a metal piece, etc., into the equipment interior from its opening section. If
does, it can cause a fire, electric shock or fault.
• Do not put a power cord close an electric heater. If does, the cord coating might melt, causing a
fire or electric shock in some cases.

• When pulling out a power plug, be sure to do it by holding the plug. If the power cord is pulled, it
damages the cord and can cause a fire or electric shock.
• Do not insert or pull out a power plug with wet hands. If does, it can cause an electric shock.
• Do not place this equipment at a place where is exposed to the direct sunlight or where is high in
temperature. If does, the internal temperature raises and it can cause a fire in some cases.
3.3 Prohibited Items in Equipment Installing Methods
• When moving this equipment, first pull out the power plug from its socket, and after making sure
that its external connecting cords have been all removed, move the equipment. Otherwise, it can
damage the cord and cause a fire or electric shock.
• Do not block the air hole of this equipment. Blocking it can cause a heat to be accumulated inside
of the equipment, causing a fire in some cases.
• Do not damage, break down or rework a power cord. If a heavy article is put on the power cord, or
if the cord is heated or pulled, the power cord is damaged, causing a fire or electric shock.
4 Preparations before Use
• Read through the operation manual (Chapter 2) carefully.
5 Using Methods
• Use this equipment following the procedures given in the operation manual.
• When a warning mark ([NOTE], [WARNING] or [DANGER]) is indicated, use this equipment
following the instructions given in the operation manual.
• Do not put any container filled with water, etc., or a small metal piece on or near this equipment.
If the water overflows or gets in this equipment, it can cause a fire, electric shock or fault.
• Do not rework, bend, twist or pull a power cord forcibly. If does, it can cause a fire or electric
shock.
• Do not disassemble or remodel this equipment. If does, it can cause a fire, electric shock or fault.
• When this equipment is not used for a long period of time, be sure to keep the plug socket removed.
If not, it can cause a fire, electric shock or fault due to a lightning.
• When the lid of printer is closed for replacement of recording paper, etc., be careful not to pinch or
hurt one's finger. Also, attention be paid to the cutter section of printer.
6 Maintenance and Inspection
• It is recommended to conduct a periodical maintenance and inspection for this equipment.
If this equipment is left for a long period of time without cleaning it with dust accumulated inside, it
can cause a fire or fault in some cases. If you have any consultations in this respect, please contact
the closest agent of our company listed at the end of the operation manual.

7 Remedial Actions Taken when Any Error Occurs
• When the power cord is damaged, ask our agent to replace it. If a damaged cord is used as it is, it
can cause a fire or electric shock.
• When a foreign matter mixes into this equipment, first turn off the power switch of its main unit, pull
out the power plug from its socket, and then contact our agent. If the defective equipment is used
as it is, it can cause a fire, electric shock or fault.
• When this equipment is used under any abnormal conditions, e.g., giving out smoke or offensive
smell, it can cause a fire, electric shock or fault. In such a case, turn off its power switch immediately
and then pull out the power plug from its socket, and after making sure that no smoke is given out
any more, ask our agent to repair the equipment. Do not repair it by the user himself to avoid any
danger from occurring.
• If this equipment is dropped down or damaged, turn off the power switch of the main unit of this
equipment, pull out the power plug from its socket, and then contact our agent. If the defective
equipment is used as it is, it can cause a fire, electric shock or fault.
• If the fan motor of this equipment is over-heated, turn off the power switch of the main unit, pull out
the power plug from its socket, and then contact our agent. If the motor is used as it is, it can cause
a fire, electric shock or fault.

PRECAUTIONS ON MOUNTING A FUSE
When mounting fuses again after you have removed the fuse holder for replacing or checking a fuse, make sure
to push in the holder until height of its face becomes even with that of the filter body (see the figure below).
While you are inserting a fuse holder, you will feel a click from this noise filter equipped (with an inlet) used on
this equipment. This noise filter is supplied from Schaffner Co.,Ltd. Note, however, that this feeling can differ
among the filters.
If you stop the insertion when you felt this click, an incomplete electric contact or no electric contact will result,
potentially resulting in blowing the fuse. Thus, reasonable care must be exercised in this operation.
