11.) Optimize the image using the TPR101 Cable EQ controls and RGB skew controls. The

TPR101 features high and low frequency controls (located on the front panel) that enhance
image detail and sharpness by boosting high frequencies and selected mid-range frequencies.
Three skew adjustments (located on the rear panel) allow users to compensate for
misconvergence (improperly aligned colors), which often occurs when high-resolution video
signals are carried over long UTP cable runs. See the External Controls Section on page 12
for more details on each control.

For best results you should adjust the TPR101 cable equalization controls
and RGB skew controls in the following order. If necessary, you may
repeat steps 2 - 4 again to fine-tune the image after the initial adjustment.

1. Before making any other adjustments, set the RGB skew controls to minimum position

(fully counter-clockwise position) useing the IN9339 adjustment tool provided.

2. Adjust the Low Frequency cable equalization control as needed to eliminate visible image

smear.

3. Adjust the High Frequency cable equalization as needed to provide a sharp image with

good detail.

4. If misconvergence occurs on the display (red, green or blue are not aligned properly), use

the IN9339 adjustment tool provided to adjust the RGB skew controls as needed to
compensate for RGB delays occuring in the CAT5 cable. The controls are delicate, so
you should only use a fine blade adjustment tool such as the IN9339 and take care not to
force the control at either end of the adjustment range.
