FSB Number: FSB LVCC2002-0075
Author: Leoncio Ramos
Date: October 7,2002
Total No. of page: 2
Subject: SNN5705B / 6mm Battery
Model Affected: All V60; T270; T280

Scope

This bulletin details the failure mode, root cause, corrective actions and action required by the field
to service customer returns for “Invalid Battery” complaint using SNN5705B.

Background

Service has been made aware of an issue with the SNN5705B battery. Samples received have shown
that the battery was not programmed. The phone will display “ invalid battery “ when attempting to
charge the battery. LED in DTC flashes red when the battery is insert in the rear pocket.

Root Cause

The battery is not programmed; it missed the blue box test on line. This was due to excessive material
accumulation at the electrical test operation. The unit went from cell pack assembly process to the
labeling station.

Corrective Action

Production personnel added new blue box tester in order to re-inspect all the packs after the battery is
programmed. The personnel were trained on electrical test operation. Only the qualified personnel at
electrical test are permitted. Packs cannot be accumulated at the electrical test operation.
If there are more than five pieces at electrical test operation the packs will be removed from operation
or the line will be stopped. Process flow and line layout was improved in order to prevent material
accumulation. Implemented under Corrective Action Report C.C. No. 2002 –04 and
8D Ref.No.020522-05-180
