Adjusting Method
4) When the focus control is finished, apply a silicon bond between inside and outside
diameter, paying attention so that the lens isn’t moved.
5) Project R, G, B signal only by one signal, using a lens cover and control G, R and B in the
order.
Note) This control should be performed in a darkroom. Especially, be careful not to touch the
lens with a hand.
Step 3. Focus control
1) Receive RETMA pattern.
2) Rotate the focus-pack of focus VR right and left to fix the optimum focus.
Note 1) Control the focus on the basis of 6cm by 6cm (intra-office signal 8CH, No.3) at the
left bottom of the screen.
Note 2) Perform the focus readjustment or correction if the entire screen isn’t focused even
after the completion of focus control.
3) Project R, G, B signal only by one color, using a lens cover and control G, R and B in the
order.
Step 4. Control of G-CRT 2-pole, 4-pole magnet
1) Receive DOT pattern.
2) Have only a green screen appear, using a lens cover.
3) Adjust the core to be located in the center of DOT, using a 4-pole magnet.
4) Adjust the DOT to be circular, using a 2-pole magnet.
5) Tighten the fixing part so that the magnet can’t move after finishing the adjustment.
Note 1) This control should be performed in a darkroom.
Note 2) Perform the focus readjustment or correction if the entire screen isn’t focused even
after the completion of focus control.
