Changing example Changing the calibration parameter C4 "frequency setting
voltage gain"
POINT
The calibration parameter C4 is an extended function parameter. Pr. 30 must be
set to "1".
2) Adjusting a deviation of the highest frequency from the Pr. 38 (Pr. 39) setting.
2)-1 Making adjustment with a voltage applied directly across terminals 2-5
(with a current flowing across terminals 4-5)

After performing operation in step 7, do not touch the setting dial
until completion of calibration.
The frequency meter (indicator) connected to across terminals FM-SD (AM-5) does not
indicate just 50Hz ... Why?
The calibration parameter C1 "FM (AM) terminal calibration" value must be set. (Refer to
page 24.)
When write is performed, an error (
