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 (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.
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.
