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. This is a Safety Class
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to an elec­
trical 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 (lEC) 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. Handl­
ing 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 per­
form 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 main­
tained.

Warnings, such as the example below, precede potentially dangerous procedures throughout
this manual. Instructions contained in the warnings must be followed.
Dangerous voltages, capable of causing death, are present in this instrument. Use ex·
treme caution when handling, testing, and adjusting.
