1General
•This document describes the process used for software upgrades and how to functionally
test the mobile phone at a Mechanical Repair Level.
•These activities can be performed at the Mechanical Repair level and higher.
•All tests must be performed.
•If the mobile passes these tests without any failures, it is OK to return it to the customer.
•If there are any failures, the mobile must be repaired according to the troubleshooting
guide or sent to a higher repair level.
•A Battery Eliminator may be used in place of a standard fully charged battery for all tests
at the mechanical level with the exception of the Battery Charger test.
2Pre-Test Preparations
2.1 Liquid Damage Inspection
Before any tests are performed, an inspection of the liquid intrusion indicator should be made
at two (2) different locations. If either liquid intrusion indicator is red this is an indication of
possible liquid exposure. If either liquid intrusion indicator suggests liquid exposure please
consult your local company for additional handling instructions.
The following images show the location of the liquid intrusion indicators.
