Appendix A: Ongoing Maintenance and Troubleshooting
INTRODUCTION
This section gives the installer or mechanic information pertaining to maintenance of the EFIS-
D100. Additionally, it provides the steps necessary to ensure continued airworthiness for the
unit.
CAUTION
With the exception of replacing the internal emergency battery, the EFIS-D100 contains no userserviceable
parts. Refer all servicing to Dynon Avionics.
INSTRUCTIONS FOR CONTINUED AIRWORTHINESS
Other than for regulatory periodic checks and an annual internal battery capacity test (if optional
internal emergency battery is installed), maintenance of the EFIS-D100 is “on-condition” only.
With the exception of the battery, periodic maintenance of the EFIS-D100 is not required.
AP SERVO INSTALLATION
At least once per year, inspect the installation of the AP servo(s) for excessive wear. Ensure that
all hardware and fasteners are tightly secured.
ALTIMETER CHECK
The following test can be performed on an as-needed basis. If the altimeter is found to be out of
specification, the following single-point adjustment can be performed by navigating the menus to
SETUP > ALTADJ. In the Altimeter Adjustment menu, you can change the displayed altitude by
up to 500 feet up or down. After making this adjustment, ensure that the altimeter on the EFIS-
D100 meets the tolerances allowed between 0 and 30,000 feet. If this adjustment does not bring
the altimeter on the EFIS-D100 to within specification at all attitudes, please contact Dynon
Avionics to return for service.
INTERNAL BATTERY CHECK
If your EFIS-D100 has a rechargeable internal emergency battery, it is necessary to ensure that
the battery capacity is such that it will last at least 2 hours on a full charge. At least once per
year, perform the following test.
1. With the EFIS-D100 drawing power from an external source, allow it to charge its
internal battery above 16.0 volts. Observe the voltmeter under the INFO selection option
in the menu system. The battery may charge to as high as 16.8 volts, but it is only
necessary to charge it to 16.0 volts for this test.
