SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation, service,
and repair of this instrument. Failure to comply with these precautions or with specific warnings
elsewhere In this manual violates safety standards of design, manufacture, and intended use of the
instrument. Hewlett-Packard Company assumes
no
liability for the customer's failure to comply
with these requirements.
GROUND THE INSTRUMENT.
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical
ground. The instrument is equipped with a three-conductor ac power cable. The power cable
must either be plugged into an approved three-contact electrical outlet or used with a three-contact
to two-contact adapter with the grounding wire (green) firmly connected to an electrical ground
(safety ground) at
the
power outlet. The power jack and mating plug of the power cable meet
International Electrotechnical Commission (IEC) safety
standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes. Operation of any
electrical instrument in such an environment constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel
must not remove instrument covers. Component replacement and internal
adjustments must be made by qualified maintenance personnel. Do not replace components with
power cable connected. Under certain conditions, dangerous voltages may exist even with the
power cable removed. To avoid injuries, always disconnect power and discharge circuits before
touching them
.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering first aid
and resuscitation, is present.
USE CAUTION WHEN EXPOSING OR HANDLING THE CRT.
Breakage of the Cathode-ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion).
To prevent CRT implosion, avoid rough handling or jarring of the instrument. Handling of the CRT shall
be done only by qualified maintenance personnel using approved safety mask and gloves.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or perform
any
unauthorized
modification
to
the
instrument.
Return the
instrument to a Hewlett-Packard
Sales and Service Office for service and repair to ensure that safety features are maintained.
