Alert Message Description End condition
REMOTE COMPASS
NOT DETECTED The EFIS-D6 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-D6
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-D6 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-D6 does not have internal
magnetic sensors and thus requires the EDC-
D10A be connected.
