Equipment Operation
Warnings and Cautions
This guide uses warnings and cautions to denote hazards.
Personal Safety Considerations
This is a Safety Class I product (provided with a protective earthing ground
incorporated in the power cord). The mains plug shall only be inserted in a
socket outlet provided with a protective earth contact. Any interruption of
the protective conductor, inside or outside the instrument, is likely to make
the instrument dangerous. Intentional interruption is prohibited. If this
instrument is not used as specified, the protection provided by the
equipment could be impaired. This instrument must be used in a normal
condition (in which all means of protection are intact) only.
No operator serviceable parts inside. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers. For
continued protection against fire hazard, replace the line fuse(s) only with
fuses of the same type and rating (for example, normal blow, time delay,
etc.). The use of other fuses or material is prohibited.
WARNING
A WARNING notice denotes a hazard. It calls attention to an operating
procedure, practice, or the like that, if not correctly performed or
adhered to, could result in personal injury or loss of life. Do not proceed
beyond a WARNING notice until the indicated conditions are fully
understood and met.
CAUTION
A CAUTION notice denotes a hazard. It calls attention to an operating
procedure, practice, or the like that, if not correctly performed or adhered
to, could result in damage to the product or loss of important data. Do not
proceed beyond a CAUTION notice until the indicated conditions are fully
understood and met.

General Safety Considerations
The following general safety precautions must be observed during all
phases of operation 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. Agilent Technologies, Inc. assumes no liability for the
customer’s failure to comply with these requirements.
User Environment
This instrument is designed for indoor use only.
WARNING
• Before this instrument is switched on, make sure it has been
properly grounded through the protective conductor of the ac power
cable to a socket outlet provided with protective earth contact. Any
interruption of the protective (grounding) conductor, inside or
outside the instrument, or disconnection of the protective earth
terminal can result in personal injury.
CAUTION
• Any adjustments or service procedures that require operation of the
instrument with protective covers removed should be performed only
by trained service personnel.
