Alert Messages
The following table describes the error/warning messages that the EFIS-D10 could display. The meaning of the message
is given here as well as information about when the error message conditions will go away.
Warning Message Meaning 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
switch power. At that point, the battery will
begin charging off the external power.
TEMPERATURE
OUT OF SPEC You will see this alert when the ambient
temperature sensed by the unit is below -30ºC
or above 50ºC. The sensors in the unit have a
certain temperature range within which they
are specified to operate normally. If they
operate outside this temperature range, the
attitude result can be compromised.
Therefore, the horizon indication will turn
from blue/brown to grey/black to indicate the
potential unreliability of the sensors while
outside the specified temperature range. The text portion of the alert will disappear
when you press any of the buttons. However,
the horizon will not display blue/brown until
the unit senses temperature within its
specified range. If ambient temperature is
above 50ºC, the unit will always display the
horizon as grey/black. However, if ambient is
below 30ºC, it is possible that the unit will
heat itself up enough to operate normally.
