We calibrated the fuel for the left tank on the left display. The other display continues to display "CAL?". We switched off the left display, and calibrated the right tank on the right display. Now we have the left indication on the left display and the right tank on the right display.
When we try the fuel flow it show on the right display, but not on the left. When we first start left, then it shows on left, not on right.
The system seems to show on both displays information, but only on the display that was first started up.
I am sure that this must be some setting, but we can not find anything about it in the manual.
