1. [Moving horizontally], adjust the H.STAT control so that
the Red, Green and Blue points are on top of each other at
the centre of the screen. R 3 & a =

Red, Green and Blue points are on top of each other at the
centre of the screen.
3. Ifthe H.STAT variable resistor is unable to bring the Red,
Green and Blue points together at the centre of the screen,
adjust the horizontal convergence with the H.STAT variable
resistor and the V.STAT magnet in the manner indicated R
below. :
{In this case, the H.STAT variable resistor and the V STAT
magnet influence each other].
Operation of the: BMC (Hexapole) magnet.
@ Tilt the VSTAT magnet and adjust the static convergence by
opening or closing the V.STAT magnet.
The movement of the magnets interact with each other and so
the respective dot position should be monitored while carrying
out this adjustment.
Use the H.STAT VR to adjust the Red, Green and Blue dots so
that they coincide at the centre of the screen
(by moving the dots in the horizontal direction).
