9 VIDEO SIGNAL ADJUSTMENT
The Video Scaler has an integral processing amplifier capable of adjusting various signal parameters of the
incoming Composite or S-Video signal. This is done by using the Select Button to choose the desired parameter
and then using the + and – Buttons to make the adjustment.
9.1 Select, + and – Buttons
Repeatedly pressing the Select Button toggles through the available adjustments, as indicated by the respective
LED. Pressing the + Button increases the value of the selection, while pressing the – Button decreases the
value. The LED will flash rapidly when the end of the adjustment range is reached. The settings are
automatically saved after adjustment and will remain in memory, even when power is switched off. Pressing
the + and – Buttons at the same time returns all settings to the factory preset levels. Note - These adjustments
have no effect on the incoming computer signals, which are simply passed through the Video Scaler.
