Operating Checklist
Before returning your instrument to Agilent for service or repair check the
following items:
Is the instrument inoperative?
q Verify that the power cord is connected to the instrument and to ac line
power.
q Verify the front panel power switch is depressed.
Does the instrument fail self–test?
q Remove all test connections to the instrument and run the self–test
again.
Errors may be induced by ac signals present on the instrument input
terminals during self–test. Long test leads can act as an antenna
causing pick–up of ac signals.
Types of Service Available
If your instrument fails during the warranty period, Agilent Technologies
will repair or replace it under the terms of your warranty. After your

Extended Service Contracts
Many Agilent products are available with optional service contracts that
extend the covered period after the standard warranty expires. If you have
such a service contract and your instrument fails during the covered
period, Agilent Technologies will repair or replace it in accordance with
the contract.
