Subject: GSM – Low/No Earpiece Audio
Model Affected: GSM V300, V303, V400, V500, V505, V525, V400p

Level of Repair: 2
Problem
Service is aware of an issue, identified during MOL Analysis, on several GSM Mid-Tier products.
Some units, returned with a customer complaint of “Low/No Earpiece Audio”, were found to have
a poor connection between the audio hinge flex and the speaker elastomer/contacts. This failure
mode is normally seen on units that have approximately 6-8 months of field exposure under a
heavy use-case. The root cause of this issue is a degradation of the integrity of the elastomer to
flex connection over time.
Solution
The product development team has identified a more robust design that replaces the elastomeric
connection with gold spring contacts. Beginning in May 2005, the factory began the process of
crossing over to the new design for all affected products listed above. The cross over schedule
started with the GSM V330 and all future products launching after May 2005. The current shipping
affected products will cross over as soon as possible to the new design, pending supplier ramp up
and parts availability. The plan is to have the new design implemented in all affected products by
August 2005.
The field will implement a proactive rework to implement the new design in all affected products
returned through the Service Network. Initial part quantities of parts have been allocated to
Service to support this rework.
