Horible sound during calls

[Guest PDAHazzard]

Hi,

Since four days my c500 suddenly has become unusable for making and taking calls, because there is a terible noise disturbing normal conversation. This noise sounds like having your GSM next to a FM-receiver or a speaker and is louder than the normal sound in conversation. I have a feeling that some sort of shield normaly preventing this kind of interferention is broken.

Has anyone any ideas on what is going on?

Oh BTW: when switched to speakerphone mode, the sound is nog hearable, thought I am not good hearable for the receiving party, who has still the same horible sound..

Regards,

Martin

I got a high pitched screeching sound intermittently with my old c500 but also noticed it a couple of times in last few months when waiting to be connected. I assumed it was a network issue.
