SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation and maintenance
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. Boonton
Electronics assumes no liability for the customer’s failure to comply with these requirements.
THE INSTRUMENT MUST BE GROUNDED
To minimize shock hazard the instrument chassis and cabinet must be connected to an electrical ground.
The instrument is equipped with a NEMA three conductor, three prong power cable. The power cable must
either be plugged into an approved three-contact electrical outlet or used with a three-contact to a two-
contact adapter with the (green) grounding wire firmly connected to an electrical ground in the power
outlet.
DO NOT OPERATE THE INSTRUMENT IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
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 the power cable
connected. Under certain conditions dangerous voltages may exist even though the power cable was
removed, therefore; 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 or rendering first aid and
resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Do not install substitute parts or perform any unauthorized modifications or the instrument. Return the
instrument to Boonton Electronics for repair to ensure that the safety features are maintained.
