Post-Repair Procedures
Configuring a Replacement Flash Memory Assembly
What to do if the instrument is non-functional and the configuration
data cannot be obtained from the instrument screen
Determine what options should be present:
The serial tag on the rear panel contains a list of the options that were
present when Agilent shipped the instrument. The option designators
can be found here. The serial tag may only provide a partial list since
options are retrofitted in the field.
Contact the instrument owner and ask them if they have license
keyword certificates for their instrument. These certificates are sent
with all field retrofit kits and list the option name and the license
keyword.
Contact an Agilent sales and service office for configuration and
licensing information for your instrument. See page 37.
