Operation
5-2 EFIS-D6 Pilot’s User Guide
The current indicated altitude is preserved across a power cycle. When powered down, the instrument saves the indicated
altitude. When it is powered up again, the instrument automatically adjusts the altimeter setting by exactly enough to
preserve that saved value. This is not a replacement for modifying the altimeter setting by the pilot before takeoff; it
makes it very close to the correct value, minimizing the amount of adjustment needed. To turn auto-set on or off, enter
the SETUP > BARO menu and set the ADJUST AT BOOT option to ON or OFF.
SETUP – Setting Preferences
Enter the SETUP menu to make changes to preferences. Many of the settings in this menu should only be changed by the
installer, and are described in the EFIS-D6 Installation Guide. The preferences and settings that are relevant to the pilot
and in-flight operation are explained below.
