5. EFIS OPERATION
This section guides you through each of the EFIS main page menu selections and their sub-menus. To enter the EFIS
menu system, press any button (except for buttons 1 and 6) directly beneath an EFIS main page. If no EFIS main page is
displayed, you must switch to a screen configuration that includes and EFIS main page as described on page 3-4.
POWER – Power on/off
When the EFIS-D10A is turned off but still has a power source via one of the three power inputs, press the far left button
to turn the unit on. Likewise, once the unit is on and no menus are displayed, push and hold the leftmost button to turn it
off. While power is still connected, the unit is never fully turned off. It simply enters an extremely low-power state,
allowing it to keep track of time. It is acceptable to have the EFIS-D10A on during engine crank. It immediately powers
on upon application of external power.
BARO – Changing Altimeter Setting
In the EFIS > BARO menu, you can adjust the altimeter
setting. When the BARO menu is displayed, the value-
setting box shows the current altimeter setting. The DEC-
and INC+ buttons change the altimeter setting by 1/100
th
inHg or 1 mbar, depending upon your selected units. As you change the altimeter setting, the altitude indicators change
accordingly. Adjust the altimeter setting until the altitude indicators display the correct altitude for your location or the
altimeter setting matches the current barometric pressure value.
The altimeter setting can be set in units of inches of mercury (inHg) or millibars (mb). To change the units, simply press
buttons 1 or 2, corresponding to the UNITS label. To reset the altimeter setting to standard day pressure (29.92 inHg),
press button 3, corresponding to 29.92 (inHg) or 1013 (mb).
