APC Back-UPS ES 700, 8 outlet. Was beeping, I turned off. After resetting I have a constant dull buzz, not the same as the alert beep, can you help?

Unsure if you lost power, but the dull buzz may be from the batteries charging. If it doesn't stop after 20 min., I suggest you follow up with the manufacturer. Here is their link: http://www.apc.com/site/support/US/en/product/BR700G/

i have had about 8 1kw or larger ups and the only time they "buzz" is when they are charging a depleted battery. i would unplug it and leave the load connected and see how long the battery last. if it dies in short period of time then probably there is a problem and the unit is charging all the time. it should go into charging mode very seldom because the load is normally not off the batteries and on the power line. the battery should stay charged and not need charging.

Know what I will have to look at mine. I simlpy haven't paid attention to that. Now I have a question for you. Do you know how to make it stop beeping all the time when there is nothing wrong? Perhaps the room temp is going outside of the perameters established. hahaha. I'll get back with you asap,Steph

I notice zero AC hum or any whine. I would use this again. I will pass on stay clear of tranmittion over AC wiring S/R units---I think Black Box was the one I used. It has a delay and gets hot.good luck

Haven't had either zone alert or noise from the one I bought. Sorry I can't be of more help. Do you think their customer service might be able to help?

I'm sorry but I checked tell instruction manual and there is nothing about the beeping. Mine is loud enough to hear even in the next room with noises in the background.

Sounds like a malfunction. Mine is completely silent. I would send it back.

The buzz is not from the amp check all of your cable connections and ground fault. We use ours all of the time and the only time we have heard a buzz was from a dimmer switch for the lights in the club.

Mine beeps with most batteries, but for very small UPS battery, sometimes the beep seems to be missing. Overall, the tester works great and I found it easy to use.

"horizontal lines and a buzzing sound" You don't say whether you tried the unit both plugged into the charger and on battery power alone. The buzzing sound might be a symptom of a faulty charger that is not converting 60Hz alternating house current to 5 volt direct current. If both the computer and the charger were healthy, the unit would boot up normally after only a few minutes of charge. My suggestion is to email Wol Vol (you can Google their website to to this) and describe the problem. Wol Vol will almost certainly instruct you to return the unit for exchange or refund; they have an excellent return policy.Joe Gunn "horizontal lines and a buzzing sound" You don't say whether you tried the unit both plugged into the charger and on battery power alone.

a little late but do you have it plugged into a power strip or a UPS? if so try plugging it into the wall directly just to see if it still beeps.. in my case it was the UPS that was causing the beeping, (under powering it)

Man, no idea. Did you get a power surge or something like that recently? I keep mine (and all electronics like this) on a suppressor protected circuit. Not much help for you now, though. You have my sympathies.

You're experiencing ground loop hum. Try using batteries only. If you still here loud hums, send it in for repair.

Mine does too. Sounded like electronic relays. Somewhat annoying but everything works.

Sounds like it needs new batteries. I read in the manual that it will continually flash or beep when the batteries are low.

You know I had to go and check! However, I have an 828LM and no hum whatsoever. Have you unplugged (the replugged) the unit and tested it away from other equipment for this humming noise?

I never noticed it. I kept an iPad, iPhone, multiple halogen-dimmed lights on within two feet of the unit . . then tried them all off, when I was having the static/hum issue. The static only came from the remote: I'm convinced of that. If you keep the system on when NOT using the audio input, you can detect a very low-level, hum from the Cyber Acoustics system being on and, I assume, "waiting." But it's NOT the static and loud hum I was hearing, when I requested a replacement remote pod. That sound was incredibly loud, harsh, and distracting. This circuit hum is almost undetectable but is present, if you're a hyper sensitive type. My AC kicks in (which is quiet) and completely camouflages this circuit hum, as the sound is so faint. There you go....
