Appendix D: Replacing the EFIS-D6 battery pack
1. Remove the three 7/64” hex screws from the battery door of the EFIS-D6. Do not remove
the Phillips or D-sub screws.
2. If you previously had a battery, disconnect it from the EFIS-D6 by unplugging the battery
connector and gently pulling out old battery. It is safe to gently pull on the battery wire to
remove the battery.
3. Insert the battery with the “bumpy” side up, toward the foam.
4. Connect the battery connector to the battery. The connector is keyed; make sure it is
positioned correctly.
5. Position the connector so it is centered on the end of the pack. Verify battery pack is
properly centered, not under screw 2.
6. Reinsert screw 2 first and tighten to 12 in-lbs.
7. Caution: Screws 1 and 3 are screwed into the extrusion and are easy to over-torque. Press
on the back plate as you insert screws 1 and 3 and tighten to 72 in-ounces.
