Reset Sunny Beam Bluetooth?

Anybody know how to reset the bluetooth on my Sunny Beam Monitor? I have an old system which was installed in 2010, it’s a Sunnyboy model SB5000US inverter. My monitor is a SunnyBeam-BT.GR1. I reset the monitor to factory settings, and when I did it reset the NetID to 0, which is a setting with Bluetooth off. The monitor will not allow me to modify the NetID to turn the bluetooth back on.

Help?!
Thanks,
Ken
