Overview
3 Overview
The Kramer VA-1H 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-1H
compensates by shifting the sync accordingly, so that the picture is properly
displayed.
To achieve the best performance:
Use only good quality connection cables1 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-1H away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

Operating the VA-1H
6 Operating the VA-1H
To operate your VA-1H:
1. Press the ON button.
2. While observing the display, press the right or left SHIFT buttons as needed
to center the picture. Depending on the resolution, the image can be shifted
up to about 1/3 of the screen in either direction.
Note: To increase the correction speed, press and hold the SHIFT button for
more than 3 seconds.
3. The setting is saved in non-volatile memory 5 seconds after the last
press/correction.
4. When the VA-1H is turned OFF and ON after a correction is made, the ON
button lights weakly to indicate a stored value.
Note: If, when the VA-1H unit is turned ON, the ON button lights brightly
and stays lit, there is a problem reading from non-volatile memory. Contact
Customer Support.
6.1 Resetting the Memory
To erase the contents of the non-volatile memory, perform the following:
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.
