2.7 INTERNAL MEMORY BACKUP BATTERY
The KLN 900 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.

2.6.2 Card Updating of User Data
Copying user data to or from a database card does not
require any hardware other than the KLN 900 and the
database card. A database card that is programmed with
a regular database can be used without changing the
database contents.
CAUTION: The user data must be updated only while
the aircraft is on the ground. The KLN 900 does not
perform any navigation functions while the user data
is being updated.
Follow these steps to copy the KLN 900 user data:
1. If user data is to be copied from a database card to the
KLN 900, turn the unit power off; remove any installed
database card as required; and insert the database card
containing the user data to be copied into the front of the
unit. (Refer to section 2.4.2 for more details on removing
and installing datacards.)
2. Turn on the KLN 900. Press E as required to
approve the Self Test and Database pages. Use the left
outer knob to select the Setup (SET) type pages and the
left inner knob to select the SET 10 page (figure 2-11).
NOTE: If the groundspeed exceeds thirty knots, user data
copy won’t be allowed and the SET 10 page will be dis-
played as in figure 2-12.
3. Press the left C . Use the left outer knob to move the
cursor over the COPY UNIT TO DB CARD? or COPY DB
CARD TO UNIT? line as appropriate.
4. Press E . The user data copy operation will begin
and the screen shown in figure 2-13 will be displayed.
5. The screen shown in figure 2-14 will be displayed upon
completion of the copy operation. Press
E to acknowl-
edge.
6. If the user data was copied from the database card to
the unit, the screen shown in figure 2-15 will be displayed.
The KLN 900 is reset following a transfer of user data to
the unit to enable the user data to be checked by various
functions performed during the startup sequence. Note
that the active flight plan 0 will be erased upon unit reset if
the installed database card does not contain a normal
database. Press
E to acknowledge and initiate a unit
reset.
If you have a problem copying the user data:
If the database card is not properly installed in the KLN
900, the unit will display DATA BASE CARD NOT PRE-
SENT. If the database card is write protected while trying
