user of th e product, sho uld follow these w arnings and al l o ther saf ety precauti ons necessary f or the sa fe
operation of the equipmentin your operating environment.
Ground the Instrument.
To minimize shockhazard, the equipment chassis and enclosure must be connected to an electrical ground. If the
equipment i s su pplied wi th a three-conductor A C p ower cable , the powe r cable m ust be plu gged in to an
approved three-contact electrical outl et, w ith t he grounding wire (g reen/yellow) reliably c onnected t o 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 and local electrical regulatory codes.
Do Not Operate in an Explosive Atmosphere.
Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or fumes.
Operation of any electrical equipment in such an environment could result in an explosion and cause injury or
damage.
Keep Away From Live Circuits Inside the Equipment.
Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or o ther
qualified service personnel may remove equipment covers for internal subassembly or component replacement
or any internal adjustment. Se rvice pe rsonnel should not replace components with power cable c onnected.
Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries,
such personnel should always disconnect power and discharge circuits before touching components.
Use Caution When Exposing or Handling a CRT.
Breakage o f a C athode-Ray Tube (CR T) cau ses a h igh-velocity s cattering o f gl ass fra gments (i mplosion). To
prevent CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment. Handling of
a CRT should be done only by qualified service personnel using approved safety mask and gloves.
