That is incorrect from the manual:
Bypass
This switch is located on the remote panel, and allows the user to bypass the computer circuit in
the EMS in the event of computer failure, this allowing AC power into the RV. This does not
disable the surge protection portion of the EMS; however, all other features are disabled.
well, all I can say is that low voltage dropout is NOT affected by the bypass switch. the dropout is NOT part of the computer circuit. it is strictly driven by the relays built in undervoltage dropout limit which is based on what voltage will keep the relay engaged. It does disable the other electronic protection, but not the dropout, at least on my unit.
And soundguy confirms it in his post as well.
