SPA504G high pitched noise

[scox00001]

Hi All,

I have an SPA504G phone, when you lift the handset to either receive or make calls it emits a continuous high pitched sound, the only way to get rid of it is to press the speaker button but then the speaker call quality is affected by a clicking sound.

Has anyone else experienced this and are you aware if it can be fixed?  I have tried replacing the handset with a new one.

Thanks

Hi Steve,

Before you RMA the unit, you should consider checking the following:

• Network cable to the wall, if there is any form of NEXT occurring it may cause this
• The Twisty cable from the hand peice to the Desk Phone, if these go faulty they can cause high pitched noises
• Is the screen showing any forms of lines on it or dimming??

You will most likely do have a faulty handset, but it is always good as a matter of courtesy to fully diagnose the phone before logging an RMA with Cisco or the Cisco Partner... At a guess it is probably a faulty capacitor which is emitting EMF and causing the issue, I had about 6 of these in one batch with the exact problem

Cheers,


David Trad.
