Level of Repair: 3, 4

Problem

Service is aware of an issue where the CDMA V810, CDMA V510, and CDMA E310
may not be able to communicate to devices via an un-powered serial cable and in
addition, some accessories may exhibit no audio conditions. This condition is the result
of an incorrect IC Switch placed by the manufacturing facility. Units with this incorrect
part will have B+ voltage applied to pin 7 of the CE Bus Connector at all times. Note
that the use of a powered serial cable, Junior Board, or USB cable will mask the issue.

Solution

Factory and part supplier have implemented improved parts verification process.
