0 IRE / 7.5 IRE
The black level output for NTSC can be set to 0
or 7.5 IRE. For North American NTSC use 7.5,
for Japanese NTSC use 0. If the button is
illuminated 7.5 IRE is selected.
Audio Calibration
Allows you to set the audio level to
avoid distortion. Ideally the first yellow
light should be almost constant and the
red light should only light up
occasionally, when loud noises occur.
