Important Service Safety Precautions; Warnings And Cautions - HP PL4260N Service Manual

Important Service Safety Precautions

BEFORE SERVICING THE PDP MODULE, READ THE
SAFETY PRECAUTIONS IN THIS MANUAL.
WHEN REPLACEMENT PARTS ARE REQUIRED, BE
SURE TO USE REPLACEMENT PARTS SPECIFIED BY
THE MANUFACTURER.
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 by the reference number in the
parts list.
WARNING: Use of substitute replacement
parts, which do not have the same
specified safety characteristics, may
create shock, fire, or other hazards.
Under no circumstances should the
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.

CAUTION: To ensure the continued reliability of
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. Keep
components and tools also at this same
potential.
WARNING:
1
Never replace modules or other components
while the unit is turned on.
2
When making settings, use plastic rather than
metal tools. This will prevent any short circuits
and the danger of a circuit becoming unstable.
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 characteristics as the
original part. Unauthorized substitutions
may result in fire, electric shock, or other
hazards.
