The first thing I did was turn off that annoying beep

and I don't like the beeping that happens when power is lost.

Every time bright colors came on the screen, there would be a loud beep

It is worth downloading the software to customize the alerts/beeping when the power fails.

I heard a long beep and failed message came up like Failure F03 or something

so I also keep it on the power supply not only for protection, but with the modem and router on the power supply me and the wife can enjoy hours of entertainment on our tablets and phones, online, with just a slightly annoying beeping sound (due to the loss of power, but I think I can probably turn it off in a setting somewhere).

The unit works and the battery tests fine, but the constant beeping makes it unusable in my office

However, as it seems to have happened with many one star reviews here, the CyberPower simply shuts off with a loud, ongoing beep, with no warning.

That same night I hear my speakers pop off in my office and a loud beep

Easy to install, easy to change settings (like the annoying beep that reminds me the power is still out).

When the power flickers I hear the reassuring beep and know that the data and hardware I can't afford to replace is protected.

Suddenly the computer shut off and there was a loud continuous beep from the UPS and it said FAULT F02.I waited about 30 minutes and decided to power up the UPS without turning anything else on

This thing could save my life!I woke up to the most annoyingly loud and obnoxious beeping I've ever heard

Battery and system were fine but the beeping got to point it would distract us from movie.

Not to mention, it has a mute feature that allows you to silence that annoying beeping sound that drives my dog insane when it's on battery power.

I don't think the beeps are too loud and the unit itself is very quiet

AND you can turn off the annoying beep when the unit activates in an outage situation

Been using this now for 6 months and not once am I interrupted with annoying beeping.

Handles the voltage drops and peaks without annoying beeping all the time.

I really don't need a super loud beeping noise every 10 seconds to remind me that the power is out.

Transition of backup power is seamless, you can't even tell it happens other than the loud beep the UPS puts out

Irrational behavior of the unit during power spikes/interruptions, very short battery power after power failure, couldn't control the annoying beeping either.

Despite the annoying beeps, I was satisfied with the battery run time of about 150 continuous minutes (2.5 hours).

The beep when it switches to battery backup during a power outage is very loud, you can definitely hear it from a room away

It started by going into a continuous beep on occasion, which could be stopped by resetting the unit, but soon the beeps happened more and more frequently until one day it just refused to do anything but the continuous beep even when reset.

The beep is also handy to let you know it's on (if there is an outage) but not so frequent that it's properly annoying

I was also surprised that I did not see any notification on my computer monitor, it was just an audible beep

Easy to setup and use though the alarm mute function is useless, as any voltage change results in a quite loud beep.
