Dynon Avionics EFIS-D6 Installation Guide - Manual (Page 36)

Appendix
5-6 EFIS-D6 Installation Guide
We recommend that you also send your EDC-D10A remote compass along with your EFIS-D6.
This ensures that if we upgrade the firmware in your EFIS-D6, the EDC-D10A will have
corresponding firmware.
While Dynon Avionics makes every effort to save and restore your unit’s settings and
calibrations, we cannot guarantee that this will happen. Please note that after you receive your
unit back from Dynon Avionics with a factory calibration, the heading display on the EFIS-D6
may be inaccurate once re-installed in your aircraft. If this is the case, you will have to perform
the magnetic calibration again. When you receive your EFIS-D6, it may have newer firmware
installed on it than it did when you sent it in. Check
downloads.dynonavionics.com for
information on what’s new.
