Service & Maintenance Cautions

exposed to electric shock, excessive tem-
peratures, or mechanical hazards.
• Performing service or maintenance not
detailed in the User’s Guide, with or with-
out 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 prod-
uct.
- The product has been dropped or dam-
aged by a falling object.
- There are noticeable signs of overheat-
ing or a burning odor.
- The product does not operate normally
when you follow the operating proce-
dures.
- The main supply fuse(s) or any internal
fuse(s) continually fail.

tact with the human body or other conduc-
tor may damage system boards or static
sensitive devices. Never perform internal
maintenance without following recom-
mended 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 com-
ponent. 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 serv-
ice 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 fac-
tory-specified parts.
• WARNING: When returning this product

second location, remove all hazardous
specimens and decontaminate the product

product cannot be decontaminated, consult
with your shipping agent on appropriate
packaging and marking.
