ups apc bk300c
I'd like to disable the sound on my APC BK300C battery backup. I found
the little device on the printed circuit board which is causing the really annoying and nasty sound. It's a black circular object. Is it possible to fill in the hole thereby muffling the sound? Or can I remove the object and re-solder something in it's place? Here's the little noise maker itself: http://www.opalfire.net/front.jpg Here's the top of the printed circuit board ... the circle is where it's located. http://www.opalfire.net/top.jpg |
Yeah I could try the masking tape thing. But I was really hoping to totally eliminate the sound. How can I cut one of the leads when it's flush on the circuit board? Thanks |

Using a sharp Exacto type knife, cut one of the traces on the pwb that
go to the sounder. Make two cuts 1/16 inch apart on whichever trace goes only to the sounder, and then use the edge of the blade to lift the copper trace between the two cuts. But I would really try the masking tape first as it should do a pretty good job and isherder to screw up than cutting a wrong trace. H. R.(Bob) Hofmann |
all joking aside, I normally crush the thing with vice grips. Solves the
issue right quick. Of course, please be sure to unplug the device and the batteries!!! bob in phx.. p.s. this is a permanent fix, where as masking tape is temp!!!!! wrote in message oups.com...

I hadn't read the above before I posted the exact fix. jak |
Sounds like a plan ... I'll let you know how it goes ... thanks for the
ideas! Since I've not had much experience with circuit boards I wasn't sure what to do. Thanks! |
All worked fine guys thanks for your help! I now have a noiseless
battery backup! I just would have assumed removing that sounder would have somehow caused the device not to work. |
