Remote Mounted Annunciators - Honeywell KLN 900s Pilot's Manual

The alert tone is provided in the same way as described
in section 3.15, "Altitude Alerting". The volume is
adjustable on the SET 9 page.
In order to use the height above airport alert, an altitude
input must be provided to the KLN 900. If the altitude
input to the KLN 900 is pressure altitude such as from an
altitude encoder or air data computer, then the altitude
must be corrected with the proper altimeter baro setting.
This is accomplished on the ALT page as described in
section 3.15, "Altitude Alerting."
CAUTION: The height above airport alert feature will
only be accurate if the altimeter baro correction is
correct. If the height above airport alert feature is
enabled, it is a good idea to update the altimeter baro
set on the ALT page each time you make a change to
the aircraft's altimeter setting.
NOTE: The altitude alerting and height above airport fea-
tures can be disabled in the KLN 900 configuration module
during installation so that these features are not selectable
by the pilot. When this has been done the SET 5, SET 9,
and Altitude pages display OFF and cannot be changed. In
addition, the SET 5 and SET 9 pages display the following :
FEATURE DISABLED.

3.17 REMOTE MOUNTED ANNUNCIATORS

The KLN 900 has outputs capable of driving two remote
annunciator lights: waypoint alert and message.
Although these annunciators are optional, it is desirable
to have them mounted in the pilot's normal scan area so
that these annunciators are easily seen. A typical
annunciator is shown in figure 3-185; however, actual
annunciation abbreviations and configurations may be dif-
ferent.
In addition, there may be a NAV/GPS switch/annunciator
to switch a CDI or HSI navigation source between the
KLN 900 and a VOR/ILS system; a GPS APR
switch/annunciator which allows display and control of the
approach modes (see section 6.1) and a GPS CRS
switch/annunciator which allows changing between Leg
and OBS modes (see section 5.9.1).
The remote waypoint alert annunciator is on whenever
waypoint alerting is occurring. See sections 3.8.6 and
4.2.2.
The remote message annunciator is on whenever the
message prompt is on. See section 3.5.
