3. Ensure that the screen is at its full brightness level. To do this, enter the menu system by
pressing any button and press DIM and increase the brightness until it will not increase
anymore.
4. Let the unit remain on for 2 hours.
5. If, after these 2 hours, your EFIS-D6 has not turned off and does not display the

at least 16.0 volts on the internal battery.
If your battery does not pass the above test, please contact Dynon Avionics and refer to
Appendix E for battery replacement instructions.
