Adjustments

The AV200R and AV201R receivers both include brightness and sharpness
adjustment dials. Additionally, the AV201R receiver is also equipped with two
extra dials to eliminate the effects of colour skew within the video image.

Brightness and sharpness adjustments

The brightness and sharpness adjustments
provided on every AV receiver allow you to
compensate for any losses incurred within
long cable links.
When making adjustments it is necessary
to have access to the AV receiver and to be
able to view one or both connected display
screens. Both adjustments, sharpness in
particular, are made easier when viewing high
contrast images with vertical edges, such as
black lines on a white background.
NOTE: Both video outputs are equally
affected by your brightness and/or sharpness
adjustments.
To display a suitable high contrast image
• Open a word processor, type the capital
letter 'H', or 'M' and increase the point
size to 72 or higher. For best results, the
background should be white and the
character should be black.
• A BLACK shadow on the right of
the character indicates UNDER
compensation.

• A WHITE shadow on the right of the
Sharpness dial
character indicates OVER compensation.
To adjust brightness and/or sharpness
1 Carefully insert a small screwdriver into the dial labelled
appropriate.
2 Slowly turn the dial clockwise or anticlockwise and observe the effect shown
on the screen. Withdraw the screwdriver when the displayed image is shown
at its optimum clarity.
3 If necessary, repeat step 2 for the other dial.
Note: If the sharpness control is set too high, the monitor may not be able
to display a picture. If this occurs, reduce the sharpness setting.
