which side is up and which end to insert into the KLN
90B. Insert the new cartridge into the back of the unit.
When the cartridge is properly inserted, the “Insert To
Here” marking on the label can just be seen protruding
from the rear of the KLN 90B (figure 2-11).
6.Make sure that the front lug of the locking mechanism
is in the up position (figure 2-9). Insert the KLN 90B
back in the rack as far as it will go.
7.Re-insert the insertion/removal tool. Turn the tool
clockwise until snug. The KLN 90B should now be locked
back into the mounting rack. Pull gently on the front
panel to verify that the unit is indeed locked into its rack.
8.The container which was used to ship the new car-
tridge to you is used to return the old cartridge back to
AlliedSignal. A return shipping label is included in the
container. Remove the backing from the label and place
it in the address position of the shipping container.
9.Insert the old cartridge into the container. Peel off the
protective backing from the adhesive on the end flap of
the container. Press the flap against the adhesive to seal
the container.
10.Please return the old cartridge promptly by mailing
immediately at any mailbox. No postage is required if
mailed from within the U.S. Users will be billed for car-
tridges not returned and no additional cartridges will be
sent until either the old cartridge or payment for the old
cartridge is received.
2.5 USER DEFINED DATABASE
In addition to the published database of airports, VORs,
NDBs, and intersections stored in the cartridge, you may
create up to 250 other waypoints. These waypoints may
be designated by you to be one of the four waypoint types
above or as a waypoint not falling into one of these types.
In the latter case the waypoint is called a Supplemental
waypoint. Section 5.4 describes how you may create a
user-defined waypoint.
2.6 INTERNAL MEMORY BACKUP BATTERY
The KLN 90B contains an internal lithium battery that is
used to “keep-alive” the user-defined database as well as
flight plans. This battery has a typical life of three to five
years.
It is highly recommended that the battery be
replaced every three years at an authorized Bendix/King
Service Center.
