Honeywell KLN 900s Pilot's Manual page 147

If it is desired to change the CDI scale factor to another
value, use the following procedure:
1. Use the left outer knob to select the MODE page.
2. Press the left C. If necessary, use the left outer
knob to move the cursor over the value of the CDI
scale (figure 5-121).
NOTE: The OCEANIC:ON/OFF field shown in figures
5-121 and 5-122 will only appear on ORS 04 and later
versions of the KLN 900.
3. Rotate the left inner knob to select the desired CDI
scale factor (figure 5-122).
4. Turn the left C off. The CDI scale factor change is
complete.
NOTE: The KLN 900 will automatically select a scale
factor while in one of the approach modes. When the
KLN 900 selects a CDI scale factor it is not possible to
select a scale factor that is less sensitive than what the
KLN 900 has automatically chosen. For example, as
you will see in the next chapter, the approach-arm
mode usually has a scale factor of ±1 NM. While in the
approach-arm mode it is not possible for you to select
the ±5 NM scale factor. This is to ensure proper
operation of the approach modes.
