SAFETY PRECAUTIONS IN THIS MANUAL.
WHEN REPLACEMENT PARTS ARE REQUIRED, BE
SURE TO USE REPLACEMENT PARTS SPECIFIED BY
Proper service and repair is important to the safe,
reliable operation of all HP equipment. The service
procedures recommended by HP and described in this
service manual are effective methods of performing
service operations. Some of these service operations
require the use of tools specifically designed for their
purpose, and should be used as recommended.
It is important to note that this manual contains various
Cautions and Notices that should be carefully read in
order to minimize the risk of personal injury to service
personnel. Improper service methods may damage the
equipment. It is also important to understand that these
Cautions and Notices are not exhaustive. HP could not
possibly know, evaluate, and advise the service trade
of all conceivable ways in which service might be
done or of the possible hazardous consequences of
each way. Consequently, HP has not undertaken any
such broad evaluation. Service technicians who use
service procedures or tools that are not recommended
by HP must exercise caution and be sure that neither
their safety nor the safe operation of the equipment will
be jeopardized by the service method selected.
Warnings and Cautions
WARNING: Critical components having special
safety characteristics are identified with a
the reference number in the parts list.
WARNING: Use of substitute replacement parts,

original design be modified or altered without
written permission from HP. HP assumes no
liability, express or implied, arising out of any
unauthorized modification of design. The service
technician assumes all liability.

this product, use only the original manufacturer's
replacement parts, which are listed with their part
numbers in the "Replaceable Parts List" section of
this service manual.
WARNING: All ICs and many other
semiconductors are susceptible to electrostatic
discharges (ESDs). Careless handling during repair
can be life-threatening. When repairing, make sure
that you are connected with the same potential as
the mass of the set by a wristband with resistance.

WARNING: To prevent electrical shock, do not use
the polarized AC plug with an extension cord,
receptacle, or the outlet unless the blades can be
fully inserted to prevent blade exposure. To prevent
electrical shock, match the wide blade or plug to a
wide slot and fully insert.
WARNING: When replacement parts are
required, be sure to use replacement parts
specified by the manufacturer or have the same
