change voltage thresholds, BV650I-MSX

[barry_rawn_apc]

Hi:  I have a BV650I-MSX supporting my internet and computing equipment.

I am in a residential area where some construction is going on. The relays inside are activating hundreds of times a day, because of temporary voltage dips.

Nothing on the UPS really needs rated voltage: it's all electronic rectifiers that really use pretty low voltage and mostly work on a universal supply (don't care of 110V or 230 V).

Not only is the sound annoying, I worry that the device will reach its end of life.

My question is this: I voided the warranty and looked inside. There's a kind of port on the motherboard.  Can I somehow use this to re-program the levels where the relays activate?
