d. Adjust CRT screw to meet tilt and orthogonal spec. ( Tilt < ±1 mm , Orthogonal < ±1.5mm )
e. Input the presetting modes and supporting modes with full white pattern.
f. Set external contrast to maximum and brightness to raster just cut-off position.
g. Press "SELECT +" or "SELECT -" to select the adjustment for H-size, H-phase, V-size,
V-center, Pincushion or Trapezoid.
h. Press "ADJUST +" or "ADJUST -" to make the geometry can meet item 9 table 2 spec.
i. Press "SELECT +" and "ADJUST -" at the same time to save the adjustment data.
j. Change timing to next mode and repeat step f, g and h.
k. After all modes are adjusted OK, turn power switch off.

e. Adjust screen VR of FBT to obtain twilight raster about 0.7 to 1.2 Ft-L.
f. See which gun appears first, then adjust the two bias VRs of the other two non-appearing guns to
achieve the color temperature meet specification x=0.281 +/- 0.005
y=0.311 +/- 0.005
g. Adjust screen VR of FBT again to let the raster about 0.7 to 1.2 Ft-L.
4. Foreground Adjustment
a. Input mode 53.6KHz (SVGA5) with 3-inch block pattern.
b. Check the drive VRs of VR104, 105 at center position.
c. Adjust external brightness key to cut-off and external contrast key to let the light output be 15
Ft-L,
d. Adjust VR103, 104 to let the color temperature meet the specification x=0.281 +/- 0.003
y=0.311 +/- 0.003
e. Adjust external contrast key to let light output be 45±3 Ft-L.
f. Press "SELECT +" and "ADJUST -" to save the adjustment data.
g. Adjust VR301 to let light output be 31±0.5 Ft-L.
h. Turn power switch off.
5. Final Check
a. Enter final check area -- press "SELECT +" and "ADJUST +" at the same time then turn power
switch on.
b. Input mode 53.6KHz (SVGA5) with full white pattern.
c. Press "SELECT +" and "ADJUST -" keys at a same time.
d. Check the light output is greater than 30Ft.L.
e. Adjust external contrast and brightness keys to minimum, the video and raster should be
disappear.
f. Check the performance of all modes can meet spec.
