INSTRUCTIONS FOR RETURN
If none of the above sections have helped resolve an ongoing issue with your EFIS-D100, please
call Dynon Avionics at 425-402-0433 to discuss the issue with Technical Support. If, after
troubleshooting with a Dynon representative, the issue cannot be resolved, we will provide you
with an RMA number to use when shipping the EFIS-D100 to us. If your unit is still under
warranty, the repairs will be performed and the EFIS-D100 will be returned promptly. If your
warranty has expired, the Dynon representative will make arrangements with you and make you
fully aware of the costs before proceeding with the repair.
We recommend that you also send your EDC-D10A remote compass along with your EFIS-
D100. This ensures that if we upgrade the firmware in your EFIS-D100, 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-D100
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-D100, it may have newer firmware
installed on it than it did
for
information on what’s new.
