This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview
The Kramer VA-1Hs UXGA Sync Shifter is a high-performance sync delay
corrector that can be used for any computer graphics video signal from
VGA to UXGA.
When sending a computer graphics video signal from a PC to a monitor via
a long-distance display cable, the delay between the picture information and
the sync may cause a horizontal shift on the display. The VA-1Hs
compensates by shifting the sync accordingly, so that the picture is properly
displayed.
To achieve the best performance:
•Use only good quality connection cables
1
to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low-quality cables).
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VA-1Hs
away from moisture, excessive sunlight and dust

1. Unplug and replug the power supply to turn the unit OFF and ON.
2. Press the left and right SHIFT buttons simultaneously for a short time.
3. When the ON button lights brightly, the operation was successful.
4. Unplug and replug the unit again to resume normal operation.
The ON button does not illuminate since there is no stored value.
