Classic Charge Controller
Q: Classic MNGP (display screen) says "MODE IS OFF" -Why?

A: Enter the Main Menu and select “Mode.” Turn the Mode “ON” and depress Enter to save. Depress Status to return to the main screen. If using the Classic for wind and you cannot turn the mode on, this may indicate the wind curve is not linear and the Classic cannot work with it. Ensure the wind curve continually goes “up hill.
