I have a Motorola Timeport 280
GSM Tri-band cell phone. The condenser
microphone seems to have become faulty as callers cannot hear me speak.
The phone works fine when I plug in an external headset+mic combo.
The microphone is the solderless type and has the numbers "64C07" on
its side. However, I cannot trace these to any equivalent or
manufacturer.
Any help shall be greatly appreciated.
Thanks.
