4-9. Knee and White Clip Adjustment
4-10. Crispening Adjustment
Note:4-10. Crispening Adjustment
The values used in the above adjustments are under the
conditions that the white clip level is set to 109 IRE (forNote:
NTSC) or 763 mV (for PAL).. Perform this adjustment on the customerOs preferences, if
When the white clip level is set to other value than 109necessary.

Specifications: Turn the MENU SEL switch (on the
front panel) once to _99, and turn
slowly for increment until the noise at
the black level of the waveform is just
decreased, or turn the MENU SEL
switch so that the crispening level is an
appropriate value.
