high-pitched whine from power adaptor

(1/3) > >>

smedicis:
Has anyone else noticed a high-pitched whine from their OBI or OBi power adaptor?  Because I'm getting one from mine.  It's not very loud but it's there.  Pretty sure it's coming from the adaptor and it goes away when I unplug the adaptor and vice-versa.

Gogyroswin:
Let me guess...you have a corded telephone that is having this issue?  There is a bigger thread about this titled "AC hum are easily heard due to the present power adaptor".  Obi has not really responded, other than to say "not" to use a different adapter or you will void your warranty, to those of us that have this issue.  It will become a bigger issue down the line with more people using the Obi more than just early adopters.

jwang:
I have the same problem. It seems not the same problem with the AC Hum one in another post. The high-pitch sound is always there, whether you are using the phone or not.

I am not sure whether it is because my power adapter is a defected one or this is a common problem for OBI110 power adapter.

Anybody else has the same problem?

It is a power adapter issue - it is harmless, but annoying. You can try to ask for replacement... If I rememebrr correctly, it is a small transformer that produce this noise.

jwang:
Yes, the sound is not loud but annoying. Where can I ask for replacement? Thanks.
