NOTE

In Case of Difficulty

provide the support you need. Before calling Agilent Technologies, however (or returning an analyzer for service), perform the quick checks listed in “Check the Basics” on page 78. This check may eliminate the problem.

If a problem persists, you may choose to:

Repair the analyzer yourself. See “Service Options” on page 80.

Return the analyzer to Agilent Technologies for repair. See “Returning an Analyzer for Service” on page 81, for more information.

No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical shock, do not remove covers.

If the analyzer is still under warranty or is covered by a maintenance contract, it will be repaired under the terms of the warranty or plan (the warranty is located at the front of this manual).

If the analyzer is no longer under warranty or is not covered by an Agilent Technologies maintenance plan, Agilent Technologies will notify you of the cost of the repair after examining the analyzer.
