PRO1200 PROVERGE SETUP

Focusing the camera lens

The lens of the camera must be focused properly on the
projection screen. Follow the steps described below :

1. In the

PROVERGE

SETUP menu, highlight FOCUS THE LENS

by pushing the

keys of the control disc.

2. Press the <ENTER>. button to start up the process.

3. A pattern of horizontal alternating green/black bars will

be projected onto the screen, together with a text box.
Inside the box, the text “CAMERA FOCUS” indicates the
item subject to adjustment and under the text, a numeric
bar scale (from 0 to 99) will visualize the correction.

4. To obtain a correctly focused camera, turn the lens until

maximum readout. The value of the stabilised maximum
readout will be in the range between 60 and 90, depending
on ambient light. In rear projection, the maximum value
can be less than 60 dependant on ambient light.

After finishing the correction, press the <EXIT> button to
return to the

PROVERGE

SETUP menu.

CENTERING THE CAMERA

The camera must be centered in the middle of the projection
screen. Follow the steps described below :

1. Highlight CENTER CAMERA by pushing the

keys of

the control disc;

2. Press the <ENTER>. button to start up the process.

Note: It is critical that the green raster of the presently

selected source is centered on the CRT faceplate.
Otherwise, the camera will not be centered properly.

CENTERING THE CAMERA HORIZONTALLY

One vertically centered green bar will be projected onto the
screen, together with a text box. Inside the box, the text of
“CAMERA ALIGNMENT HORIZONTAL” indicates the item subject
to adjustment and a symmetrical bar scale (from -50 to +50)
under the text.

If the indicated value below the bar scale is not equal to zero
(i.e. the black highlight is not in the middle of the bar
scale), the camera is not centered horizontally. Follow the
steps below to center the camera horizontally:

3. Turn the screw situated on the upper-right corner of the

camera clockwise or counter clockwise until the highlight
is in the middle of the bar scale (i.e. the indicated value
becomes zero);

4. Press the <ENTER>. button to continue with the camera

vertical centering.

Note: When centering a retro projector this option is not

required as the camera is fixed inside the retro using
the camera support plate (part 12 on page 2-1.)

Centering the camera vertically

One horizontally centered green bar will be projected onto
the screen, together with a text box. Inside the box, the text
of “CAMERA ALIGNMENT VERTICAL” indicates the item
subject to adjustment and a symmetrical bar scale (from -50
to +50) under the text.

If the indicated value below the bar scale is not equal to zero
(i.e. the black highlight is not in the middle of the bar
scale), the camera is not centered vertically. Follow the steps
below to center the camera vertically :

5. Turn the screw situated on the lower-left corner of the

camera clockwise or counter clockwise until the highlight
is in the middle of the bar scale (i.e. the indicated value
becomes zero).

After finishing the vertical centering, press the <ENTER>.
button to return to the

PROVERGE

SETUP menu.

When installed in a retro projector, the centering procedure
is not necessary and not possible as the camera mounting
is fixed.

Set Touch-up options

For convergence purpose, the screen is divided into 25
areas. Every area has its unique number from 1 to 25.
Touch-up adjusts the Area No. 1. This adjustment is also
called the “static convergence”.

The Touch-up can be set on Source or on Timer.
Touch-up on Source means when switching from one source
to another, the static convergence will be carried out
automatically.
Touch-up on Timer means whenever the user-defined period
of time has elapsed the static convergence will be adjusted
automatically.

TOUCH-UP ON SOURCE ON/OFF

Follow the steps below to set the option ON or OFF :

1. Push

keys of the control disc to highlight ON

SOURCE SWITCH: off

2. Press the <ENTER>. button to toggle between ‘ON /’OFF’.

3. Press the <EXIT> button to return to the

PROVERGE

menu.

Note:Touch-up on Timer

This option allows the static convergence to be
carried out automatically after a user-defined time,
which can be programmed in hours and/or minutes.
