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 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 at 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 of rendering first aid and resuscitation, is
present.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Do not install substitute parts or perform any unauthorized modification of the instrument. Return the instrument to
Boonton Electronics for repair to ensure that the safety features are maintained.
SAFETY SYMBOLS
This safety requirement symbol (located on the rear panel) has been adopted
by the International Electrotechnical Commission, Document 66 (Central
Office) 3, paragraph 5.3, which directs that the instrument be so labeled if, for
the correct use of the instrument, it is necessary to refer to the instruction
manual. In this case it is recommended that reference be made to the
instruction manual when connecting the instrument to the proper power
source. Verify that the correct fuse is installed for the power available, and
that the switch on the rear panel is set to the applicable operating voltage.
The CAUTION sign denotes a hazard. It calls attention to an operation
procedure, practice, or the like, which, if not correctly performed or adhered
to, could result in damage to or destruction of part or all of the equipment. Do
not proceed beyond the CAUTION sign until the indicated conditions are
fully understood and met.
The WARNING sign denoted a hazard. It calls attention to an operation
procedure, practice, or the like, which, if not correctly performed or adhered
to, could result in injury or loss of life. Do not proceed beyond a WARNING
sign until the indicated conditions are fully understood and met.
