9. To enter the correct baro setting, rotate the right inner
knob to select the first two digits of the correct altime-
ter setting (figure 3-19). Rotate the right outer knob
one step clockwise to move the flashing cursor over
the third position. Use the right inner knob to select
the correct number. Use the right outer and inner
knobs to complete the baro setting (figure 3-20).
Now press E.
10. With the correct altimeter setting entered, the altitude
displayed on line 4 should be correct within 100 feet.
11. Turn the right outer knob clockwise to position the
cursor over APPROVE? if it is not there already
(figure 3-21). Press E to approve the Self Test
page. If the KLN 90B altitude alert audio is utilized in
the installation, five beeps should be heard when the
Self Test page is approved. The alert audio volume
may later be adjusted on the SET 9 page. (Note: If
the KLN 90B is installed for VFR only operation, a
VFR only warning page is displayed after the self
test page has been approved (Figure 3-22). This
warning page must be acknowledged by pressing
E .) If the KLN 90B is installed with an external
GPS CRS switch and the switch is in the OBS
position, then the OBS warning page will be
displayed (figure 3-23). The GPS CRS switch
should be pushed so that the LEG mode is
selected.)
12. The Database page will now be displayed with the
cursor over ACKNOWLEDGE?. Line 1 indicates the
coverage area of the database being used. If the
database is current, line 3 will show the date when
the database expires (figure 3-24).
If the database is out of date, line 3 shows the date
that it expired (figure 3-25). The KLN 90B will still
function with an out of date database; however, you
must exercise extreme caution and always verify that
the database information is correct before using infor-
mation from an out of date database.
Press E to acknowledge the information on the
Database page.
WARNING: The accuracy of the database information
is assured only if the database is current. Operators
using an out of date database do so entirely at their
own risk.
