My GH2106 fridge is showing E1 error? The GH2106 display is in Fahrenheit? How to unlock the GH2106

This E1 message appears on the display when the fridge senses that the external battery voltage is too low. The fridge will stop running, to preserve the battery capacity.

E1 can also be caused by the power cable being too long, or a loose plug connection. You can customise how low a voltage the fridge will accept before the fridge displays E1 and stops running.
