Manage Self Test on Back-UPS BR1200G

[Urukhai]

I have a Back-UPS BR1200G backing a NAS device and a ubuntu server for a small shop. Previously self-tests were done in the early morning (ie. 3:00 am) that I can stand with.

However the last few self-tests happen during weekday office hours which I think is catastrophic in my option. If the battery is bad, then this UPS creates its own power outage instead of protecting it.

I understand self-test is performed every 14 days. Are there any ways to set  the time when self-test should be done. Or come to the worse, how I can disable self test if it cannot be scheduled properly.
