3-2. CONVERGENCE
(1) Horizontal and Vertical Static Convergence
1. Receive the channel with dot signal.
2. Minimize BRT and set picture level to the position where the
dot is easy to see.
3. Adjust horizontal convergence at the centre of the screen with
V. STAT correction piece.
4. Adjust vertical convergence of dot at the centre of the screen
with V. STAT MG.
5. Adjust repeatedly static convergence according to righe figure
in case that both HMC and VMC are not independant.
In case of both HMC and VMC exist attach BMC magnet to
neck assembly.
Case of HMC attached
Turn BMC over in case of adjustment in opposite direction.
Use BMC mg only when it is necessary, for it makes CRT focus
worse.

• Movement of red, green and blue dots by V. STAT tilting
and opening or closing.

• If the blue dot did not harmonize with red and green,
then use the BMC magnet to adjust.
