No operator serviceable parts inside. Do not install substitute parts or
perform any unauthorized modifications to the instrument. Return the
instrument to Keysight for service and repair to ensure the safety features
are maintained in operational condition. Instruments that appear damaged
or defective should be made inoperative and secured against unintended
operation until they can be repaired.

hazardous voltage source, the instrument and the device under test should
be supervised, following local EHS practices to restrict access.
