Additional Precautions for Service Engineers

DO NOT substitute parts or modify equipment. Because of the
danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification to
the product. Return the product to an Agilent Sales and Service
Office for service and repair to ensure the safety features are
maintained.
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.
Review "Safety Precautions" on page 23.
See "Optical Connector Safety Information" on page 46 before
making connections to the instrument.

ESD Precautions

When making connections to the instrument, review "Optical
CAU TI O N
Connector Safety Information" on page 46.
The instrument contains components sensitive to electrostatic
discharge. To prevent component damage, carefully follow the
handling precautions presented below.
The smallest static voltage most people can feel is about 3500
volts. It takes less than one tenth of that (about 300 volts) to
destroy or severely damage static sensitive circuits. Often, static
damage does not immediately cause a malfunction but
significantly reduces the component's life.
