Gone for a few months. On return, tach time and hobbs time are zero. Battery did not go dead, engine started right up. Tach seems to be accurate, at least at idle. Ideas as to why, and how can I reset to last times before zero?

Thanks,
Larry

P.S. ticket submitted as well.

Replace the CR2032 backup battery in the instrument.
Then use the setup menu to reset Hobbs time.
The manual will tell you how- you can download from the mglavionics.co.za website.
