Alert Message
Description
End condition
INTERNAL BATTERY
LOW
You will see this alert only when operating the
unit solely off the internal backup battery. When
its voltage has dropped below a certain threshold,
you will see this alert. Additionally, the voltmeter
will be displayed onscreen. When you see this
alert, it is advisable that you turn the unit off by
pressing the POWER button in Main Menu 1.
The alert will disappear when you press any
button; however, it is advised that you do not
ignore this alert, as it appears when the unit’s
internal battery has very little life left. This alert
will also go away upon the application of either
the external backup battery or Master Power. At
that point, the battery will begin charging off the
external power.
REMOTE COMPASS
NOT DETECTED
The EFIS-D10A is unable to communicate with
the EDC-D10A. If you have an OAT connected
to your EDC-D10A, you will lose this reading, as
well.
Ensure that you a) have an EDC-D10A installed
and b) have verified that the wiring to the EDC-
D10A is correct. Please see the EFIS-D10A
Installation Guide for more information on
verifying the installation of the EDC-D10A.
This error also can appear if you have updated
the firmware in your EFIS-D10A while the
remote compass was not connected. If this is the
case, try uploading the new firmware again with
the EDC-D10A connected. Attempt the
connection within the first few seconds of
operation.
Note that the EFIS-D10A does not have internal
magnetic sensors and thus requires the EDC-
D10A be connected.
