Caution
Do not exceed the operating input power, voltage, and current
level and signal type appropriate for the instrument being used, refer to
your instrument's Operation Manual.
Electrostatic discharge(ESD) can damage the highly sensitive
microcircuits in your instrument. ESD damage is most likely to occur as
the test fixtures are being connected or disconnected. Protect them from
ESD damage by wearing a grounding strap that provides a high
resistance path to ground. Alternatively, ground yourself to discharge any
static charge built-up by touching the outer shell of any grounded
instrument chassis before touching the test port connectors..

Safety Summary
When you notice any of the unusual conditions listed below, immediately
terminate operation and disconnect the power cable.
Contact your local Agilent Technologies sales representative or
authorized service company for repair of the instrument. If you continue
to operate without repairing the instrument, there is a potential fire or
shock hazard for the operator.
