Digital Setup

Your Zenith Projection TV has three color projection tubes: one for red, one for green, one for blue. When mixed together in the proper
proportion, the output of these three color tubes can produce any color. To produce these colors, however, the beams must be
precisely aligned over each other so that the colors can be mixed. The process of aligning these picture beams is called "convergence".
Over a period of time, the picture tubes can drift out of alignment due to normal bumps and vibrations or moving the TV. If you move
your TV, or if, after a time, you notice color rings or halos around objects in the picture, you may want to converge (align) the colors.
Properly converged, the lines appear white, which is actually a combination of the outputs of the three color tubes. The output of the
green tube is stationary. The outputs of the red and blue tubes can be adjusted. When properly aligned, the outputs of all three tubes
should be directly over each other to produce the white lines.
To simplify convergence, Zenith incorporates a feature to allow you to display a test pattern of horizontal and vertical lines at one
location on the screen. Simply use the remote control to adjust the red and blue colors to match the green. When properly aligned,
the outputs of all three tubes should be directly over each other to produce the white lines.
To enter this adjustment mode, press the front panel DIGITAL SETUP button.
Press the ARROW buttons on the remote control to move the displayed color up, down, left, or right. (Press the QUIT button to toggle
between red and blue.)
Press MENU on the remote control to change the color you want to adjust.
Press the front panel DIGITAL SETUP button or the remote control MENU button when adjustment is done. This will save your adjustment
into memory.
NOTES: Only a momentary press of the DIGITAL SETUP button is necessary to enter DIGITAL SETUP convergence adjustment mode.
Do not press the DIGITAL SETUP button for more than three seconds.
To save your adjustment data into memory, press the front panel DIGITAL SETUP button or the remote control MENU Button.
If you do NOT wish to save your adjustment data into memory, turn the TV OFF. When the TV is turned ON again, your old
convergence data will be restored.
To exit this function, press DIGITAL SETUP on the front panel of your Entertainment Machine.
