Calibrating gray tank sensors....

[footdoc]

My gray tank will take a while to show 1/4 full, then very quickly will show full after a disproportional extra amount of water goes in....
How do I calibrate the sensor....start with a full tank, press the red button, then empty and press the red button??? or the other way????

On mine I place a sharp object on the F or E buttons and hold for 5 seconds, that recalibrates.

I just went thru this last week. My tanks were not reading correct. I tried a few times on my own with no luck.. I called NEWMAR tech, and they explained it is a 2 step process. 1st, drain the tank completly. The pess and hold the "E" button for 5 sec. and the lights will flash. 2nd fill the tank full, Then press and hold the "F" button for 5 sec. and the lights will flash. You are all set...VACMAN
