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. 
2.
  Remove all sources of external power from the FlightDEK-D180, ensuring that it is 
operating off its internal battery. 
3.
  Ensure that the screen is at its full brightness level. To do this, enter the menu system by 
pressing any button beneath an EFIS page (except the far left or far right hotkeys) and 
press MORE > DIM and increase the brightness until it will not increase anymore. 
4.
  Let the unit remain on for 1.5 hours. 
5.
  If, after these 1.5 hours, your FlightDEK-D180 has not turned off and does not display 
the INTERNAL BATTERY LOW warning, your battery passes the capacity test. 
6.
  Make sure you recharge your battery; a full charge is reached when the voltmeter shows 
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 G for battery replacement instructions. 
  Please dispose of non-functional backup batteries in a responsible manner. Backup 
batteries are lithium-ion and similar in construction to cordless tool batteries. They can 
likely be recycled wherever cordless tool battery recycling is available. For a list of 
recycling locations in your area (USA only), call 1-800-8-BATTERY or see the Call 2 
Recycle website at www.rbrc.org. 
FIRMWARE UPGRADE 
Dynon Avionics provides free firmware updates for all its products, and continues to add new 
features periodically. We suggest that you regularly ensure that your FlightDEK-D180 has the 
latest firmware by visiting our website at downloads.dynonavionics.com
 and downloading the 
latest Dynon Product Support Program. This software contains the latest firmware updates for all 
our products. 
Each Dynon EMS or EFIS must be individually upgraded by connecting a PC to that 
instrument’s serial port. The HS34 also must be individually upgraded via its Serial 1 port. 
Firmware upgrades to EDC-D10A, AP74, and SV32/42/52 are performed automatically during 
firmware upgrades of the attached EFIS product. (Upgrading a non-DSAB-bus-master EFIS will 
not update attached autopilot devices).
