1 Key sequences on the Digital Operator are enabled. (see note 2)
Note 1. The maximum frequency (FMAX) is set when the FREQ adjuster is set to MAX.
Note 2. The frequency reference can be set with key sequences while the FREF indica-
tor is lit or with the set value in n21 for frequency reference 1. In either case, the
value is set in n21.

Regardless of the methods of operation mode and frequency reference in-
put, the upper and lower frequency reference limits can be set.

•
Set the upper and lower frequency reference limits as percentage based on the maxi-
mum frequency as 100%.
