INSTRUCTIONS FOR RETURN
If none of the above sections have helped resolve an ongoing issue with your EMS-D120, 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 EMS-D120 to us. If your unit is still under
warranty, the repairs will be performed and the EMS-D120 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.
While Dynon Avionics makes every effort to save and restore your unit’s settings and
calibrations, we cannot guarantee that this will happen. When you receive your EMS-D120, it
may have newer firmware installed on it than it did when you sent it in. Check
mation on what’s new.
