BendixKing KLN 900 - Abbreviated Guide - Manual (Page 54)

The KLN 900 can provide the aural alarm tones in either of two ways: it
may be connected to an audio input of an audio amplifier contained in an
audio panel so that the aural alarm is heard through the aircraft’s speaker
and headphones. Or the KLN 900 may be interfaced with an external
tone generator installed in the aircraft.
In order to use altitude alerting, the KLN 900 must have an altitude input.
If the altitude input is from an altitude encoder or from an air data com-
puter not having a baro altitude output, then it will be necessary for you to
manually input the proper altimeter setting in order to get accurate
alerting. Remember, the altitude coming from an encoder is pressure alti-
tude and must be corrected with the proper altimeter setting to convert to
actual altitude. This altimeter setting is easily accomplished by entering
the altimeter baro setting on the Altitude page. Press
A to display the
Altitude page. Use the left knobs to make the altimeter baro setting.
Press
A again to return to the pages previously being displayed. It’s so
easy you have no excuses for not keeping the baro setting updated!
CAUTION: The altitude alerting feature will only be accurate if the
altimeter baro correction is kept updated. If altitude alerting is used,
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.
The volume of the aural alarm tone is changeable on the SET 9 page.
Press the left
C to activate the left cursor and use the left inner and
outer knobs to select a desired value between 00 and 99. Increasing
numbers increases the volume.
15.0 UPDATING THE DATABASE
The database is housed in a PCMCIA card which plugs directly into the
front of the KLN 900. It is designed so that there are two ways for the
user to keep the database current. Honeywell makes these two types of
update services available to you in a choice of several subscription or
random update programs. See section 2.8 of the KLN 900 Pilot’s Guide
for details on these programs.
The first method of database update is to remove the old card and insert a
current card. This method involves returning the old card to Honeywell.
This method is described in this section of the manual but more detailed
instructions are presented in section 2.4.2 of the KLN 900 Pilot’s Guide.
Because of the wide range of shipping costs and import/export regulations
for different countries, this method is available for use only in the United
States.
