Safety Considerations

Read the information below before using this instrument.
The following general safety precautions must be observed during all phases of
operation, service, and repair of this instrument. Failure to comply with these
precautions or with specific warnings elsewhere in this manual violates safety
standards for design, manufacture, and intended use of the instrument. Keysight
Technologies assumes no liability for the customer's failure to comply with these
requirements.
This is a Safety Class I instrument (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 of the instrument is likely to make the instrument
dangerous. Intentional interruption is prohibited.
DO NOT operate the product in an explosive atmosphere or in the presence of
flammable gases or fumes.
DO NOT use repaired fuses or short-circuited fuseholders: For continued
protection against fire, replace the line fuse(s) only with fuse(s) of the same
voltage and current rating and type.
DO NOT perform procedures involving cover or shield removal unless you are
qualified to do so: Operating personnel must not remove equipment covers or
shields. Procedures involving the removal of covers and shields are for use by
service-trained personnel only.
DO NOT service or adjust alone: Under certain conditions, dangerous voltages
may exist even with the equipment switched off. To avoid dangerous electrical
shock, service personnel must not attempt internal service or adjustment unless
another person, capable of rendering first aid and resuscitation, is present.
DO NOT operate damaged equipment: Whenever it is possible that the safety
protection features built into this product have been impaired, either through
physical damage, excessive moisture, or any other reason, REMOVE POWER and
do not use the product until safe operation can be verified by service-trained
personnel. If necessary, return the product to a Keysight Sales and Service Office
for service and repair to ensure the safety features are maintained.
