How to turn off beeping in APC Easy UPS BV1000I-Gr

[vitalia]

Hello good people,
I have just got an APC Easy UPS, Model No. (BV1000I-GR).When I'm working on battery, it produces the sound of 4 peeps every 30 seconds. How can I turn of this peeping sound and may be leave the beeping of "low battery" knowing that the device only has an On/Off button on the side,  a circuit breaker on the other side and 4 socket on top.

Thanks in advance

I'm facing the same issue, no mute button or exposed USB port, I really want to mute it because electricity goes out daily in Egypt, and usually at night, and I don't want to disturb my neighbors.
