OPERATION
Most adjustments require removing the top cover. To access the bottom unit in a dual (X2) version, remove
the 2 screws holding the top demod to the front panel. To access the internal adjustments, it is not necessary to remove
the demod from the front panel; just remove the top cover screws. Figure 2 shows the adjustment locations. When all
adjustments are complete, replace the top cover. For X2 units, repeat this process for the top unit.
MODE SWITCH
This switch selects the CATV tuning mode. It is accessed through a hole in the top cover. Only positions
6-9 are valid settings on PAL units. Positions 0-2 select traditional channel plans. Positions 3-5 select EIA stan-
dard channel plans. Positions 6-9 select direct frequency tuning.
