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.
OAT SENSOR
NOT
DETECTED
This alert appears when the EFIS has
an OAT connected and then loses
that connection for some reason.
Either the EDC-D10A has become
disconnected, or the OAT sensor
itself has become disconnected from
the EDC-D10A.
Double-check your wiring between
the EFIS-D10A and the EDC-D10A
as well as that of the OAT sensor.
