REMOTE CONTROL
The module CR contains all the image control trimmers and is connected to the mother board by a male
connector (J 107); this permits the module to be disconnected from the mother board, and re-connected via
a 1.5m extension cable (available as an extra), giving the ability tor an operator to make all necessary
adjustments from in front of the game cabinet. The extension cable and plastic support tor the module can be
ordered as «Remote Control Unit» code no. 62016260. (See illustration).

ARNING
(see attached circuit)
A vertical bar generator used by an operator tor a rapid check on the functioning of
the video circuitry and for geometry adjustments. To activate the function generator,
move the bridge on the •Test
into the "ON" position.
Alternatively it fu nctions as a vertical and horizontal blan ki ng generator in those cases
where the logic board does not provide blanking, or where the blanking pulse
available is less than 7 µs; in this way irregular colouration or horizontal fly back
lines of differing colours in certain parts of the screen can be eliminated.
As supplied the monitor has the artificial blanking circuit unactivated. To
activate this function, remove the bridge P152.
In this condition, the monitor still functions in the presence of a normal external
blanking signal.
