OPERATING THE UNITS
Once the connections have been made and power applied, there is little in the way of
operational adjustments required. All Receivers have Equalization and Gain
adjustments. Additionally, the 1T-CT-444 and 1T-CT-456 have Skew Compensation
adjustments.
5.1
Equalization and Gain Adjustments
On all Receiver models, locate the EQ (Equalization) and GAIN adjustments on the side
of the Receiver.
On long cable runs, the high frequency detail can be lost resulting in a “soft” looking
picture. This will first show up in text where the characters will lose their sharp edges.
Adjust the EQ can sharpen the image. While viewing an image on a display connected
to the Receiver, insert a small screwdriver into the EQ adjustment on the side panel of
the Receiver. Rotate gently until the best EQ setting, as determined by image clarity, is
achieved.
Then insert the screwdriver into the GAIN adjustment, and rotate gently until the best
Gain setting, as determined by the brightness of the image is achieved. You may
notice an increase in video noise (sometimes called “snow”) in the picture at higher
gain settings so a compromise will have to be found if the cable run is at or near the
maximum length. EQ and GAIN settings are retained by the Receiver.
5.2
RGB Skew Compensation Adjustment
RGB images transmitted over long Cat.5/5E or Cat.6 cable paths can sometimes arrive
at the destination with the individual RGB pictures no longer in registration. Models 1T-
CT-444 and 1T-CT-456 have built in Skew Compensation adjustments to correct this.
This adjustment should be made after the EQ and Gain adjustments described above. A
good test pattern for RGB Skew adjustment is pictured below and is available for
download at the TV One Technical Support website

. After
saving the test pattern on the source PC, display and view it while making adjustments
on the remote display.
