Service & Maintenance Cautions
• Unplug the power cord prior to opening
or removing covers, or else you may be
exposed to electric shock, excessive
temperatures, or mechanical hazards.
• Performing service or maintenance not
detailed in the User Guide, with or without
this Service Manual, should only be done
by a qualified service technician.
• Never restrict airflow into or out of the
product. Occasionally, check the air vents
for blockage.
• Wipe the exterior of the product with a
soft, damp cloth as needed. Using cleaning
products other than those specified, may
discolor or damage the finish.
• If the product requires service for any of
the following reasons, unplug the product
from the electrical outlet and refer service
to a qualified service technician.
- The power cord, extension cord, power
strip or power input module is damaged.
- Liquid has been spilled into the interior
of the product.
- A foreign object has fallen into the product.
- The product has been dropped or
damaged by a falling object.
- There are noticeable signs of
overheating or a burning odor.
- The product does not operate normally
when you follow the operating
procedures.
- The main supply fuse(s) or any internal
fuse(s) continually fail.
• A discharge of static electricity from
contact with the human body or other
conductor may damage system boards or
static sensitive devices. Never perform
internal maintenance without following
recommended static protection procedures.
• The product is equipped with operator
accessible fuses. If a fuse blows, it may
be due to a power surge or failure of a
component. Replace the fuse only once.
If the fuse blows a second time, it is
probably caused by failure of a component
part. If this occurs, refer service to
qualified service personnel. Always
replace the fuse with one of the same
rating, voltage, and type. Never replace the
fuse with one of a higher current rating.
• When servicing the product, use only
factory-specified parts.
• WARNING : When returning this product
for service, or shipping this product to a
second location, remove all hazardous
specimens and decontaminate the product
before packaging for shipment. If the
product cannot be decontaminated, consult
with your shipping agent on appropriate
packaging and marking.
