Internal Lithium Backup Battery
A lithium battery maintains the test tool’s memory contents when you remove the
NiMH battery pack. The memory contents maintained are the stored Autotest
reports, all SETUP settings, self-calibration and NVP calibration data, custom test
configurations, and the report identification information.
The lithium battery lasts about five years if you always keep the main battery
installed. Removing the main battery pack for extended periods shortens the life of
the lithium battery.
When the lithium battery voltage is low, have the battery replaced at a Fluke
Networks Service Center. See the later section “Service Center Repair” for
shipping and warranty information.
If the Test Tool Fails
If the test tool does not operate properly, refer to Table 8-1 on the next page for
troubleshooting procedures. If the self-test fails, return the unit for service as
described in “Service Center Repair.”
Service Center Repair
If the test tool requires service, call an authorized Fluke Networks Service Center
for return instructions.
A test tool covered under warranty will be promptly repaired or replaced (at Fluke
Network’s option) and returned to you, postage paid, at no charge. See the
