or the front panel rotary knob can be used to change the value. After the new value has been entered,
press the [Hz] key to retain the new values in "working memory area.

Procedure to Store the Calibration Constants

After adjustments of the calibration constants are completed, the data thus stored in the "working
memory area" should be copied to the "protected memory area" by pressing the following key
sequence:
[SHIFT][MHz] [1] [4] [Hz]
[SHIFT][kHz][5] [3] [4] [9] [Hz]Wait
