* Unless instructed otherwise, the CRT face should be facing to the east.
* Degauss the entire unit with an external degaussing coil for the adjustment.

Notes about degaussing method
Follow the degaussing procedure below. (To prevent intertwinement of aperture grille)
1) Use cylinder-shaped degaussing coil. Do not use ring degaussing coil. But ring degaussing coil can be
used at degaussing chassis.
2) In order to remove a magnetization from top sides, base shield and chassis, degauss each side.
Do not switch off the degaussing coil abruptly. Move the degaussing coil slowly when degaussing.
Note: If the degaussing coil is switched off near the set, the set will be magnetized.
3) To degauss panel surface
Switch on the degaussing coil, keep a distance between panel surface and degaussing coil to more than 50
cm. Move the degaussing coil vertically near the panel surface.
Keep distance of panel surface and degaussing coil to more than 15 mm.
4) Degaussing method of CRT surface
Starting from edge of CRT, move the degaussing coil toward CRT center in circular motion, spending 6 to 7
seconds. (about 4 or 5 round )
When LED is orange in factory mode (
“
AUTO EMF ON
”
appear on OSM or TAG 3, TAG 4, TAG 5, TAG B,
TAG C is selected), Do not degauss.
In user mode, do not degauss except when
“
DEGAUSS OK
”
appear on OSM.
Service Factory MODE: Auto EMF function is off. (LED is yellow)
Auto EMF function off -> on (LED is orange.)
a. TAG 3, TAG 4, TAG5, TAG B, TAG C is selected.
b. When OSM MENU disappear, Push
“
+
”
and
“
!
”
switch at once.
Then
“
AUTO EMF ON
”
appear on OSM, and AUTO EMF function
is on state.
Push any switch and power on/off, AUTO EMF function become off state.
But when receive frequency change, AUTO EMF function stay on state.
