The first column lists each frequency (in MHz) of the frequency/cal factor pair. The second
column lists each cal factor (in
%)
of the frequency/cal factor pair. (The first frequencyhal factor
pair listed is the reference cal factor that
is
measured a t 50 MHz. This frequency cannot be
changed.) To enter new frequency/cal factor pairs,
