Help needed in muting out the alarm(beep) sound of zebronics UPS!

[Bobbyguitarist]

i have a zebronics UPS bought 3 years back and when the power goes..back up kicks in...all is fine..but when back up is on ..it makes alarm (beep) sound every 10 seconds or so like any other UPS! well this feature gets pretty annoying when i leave the system on for the night for downloading and power goes out at night!So is there any way to shut out those beep sound.?also UPS is out of warranty so am not adverse to the idea of opening up the UPS 😛

^^ there is usually a small speaker attached and placed along with blinking led (inside ofcourse). open ups, if you find it, you know what to do with it or search for a diagram online if there is one.
