If it is desired to change the CDI scale factor to another
value, use the following procedure:
1. Select either the MOD 1 or MOD 2 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 5-120).
3. Rotate the left inner knob to select the desired CDI
scale factor (figure 5-121).
4. Turn the left C off. The CDI scale factor change is
complete.
NOTE: The KLN 90B will automatically select a scale
factor while in one of the approach modes. When the
KLN 90B selects a CDI scale factor it is not possible to
select a scale factor that is less sensitive than what the
KLN 90B 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.
