This adjustment should be made only when the chroma/video (1601) or parts of the APC circuit have been replaced,
or when the picture colors are unstable. For adjustment, use the APC, ADJ control (C613).
Procedures
. Apply a color bar signal to the video input terminal.
. Turn the color control fully clockwise and position the tint control at the mechanical center.
. Connect a jumper wire between pin 11 of 1201 and ground line.
. Turn the APC, ADJ control (C613) with an insulated screwdriver until the color bar on the screen is synchronized.
. Removed the jumper wire and capacitor.

High voltage is not adjustable but must be checked to verify that the monitor is operating within safe and efficient
design limitations as specified:
1. Remove cabinet back.
2. Operate monitor for at least 15 minutes at 220V AC line with video signal or test signal properly tuned in.
3. Rotate the brightness and contrast controls to maximum clockwise position.
4. Connect an accurate high voltage meter to CRT anode.
Reading should be between 23KV and 25KV.
_ CONTROL
DE HAUTE TENSION |
La haute tension n'est pas reglable mais doit etre controlee afin de s'assure que le moniteur foncitionne d'une mesure
de securite et d'efficacite determinee par le cahier des charges. Pour le faire:
1. Enlever le couvercle d'arriere du cabinet.
2. Faire fonctionner le moniteur pendant au moins 15 minutes a la ligne de 220V, AC en accordant correctement
le signal de video ou celui d'essai.
3. Tourner a fond les commandes de brillance et de contraste dans le sens de aiguilles d'une montre.
4. Brancher un voltmetre de haute precison sur l'anode de CRT. La valeur relevee doit etre comprise entere 23KV
et 25KV.
The vertical position control (R318) is the VR which controls the vertical position of the picture.
If the vertical position of the picture is not at the center of the picture tube, adjust the vertical positon by turning this
control.
