※Notes about degaussing method
Follow the degaussing procedure below. ( For prevent intertwinement of aperture grille. )
1) Use stick type degaussing coil at degaussing CRT. Do not use ring degaussing coil.
But ring degaussing coil can be used at degaussing chassis.
2) Open Menu (U),TAG 7 "DISPLAY MODE" and push "PROCEED".
3) Push "+" SW and "▲" SW at the same time.
4) Confirm to display "DEGAUSS OK"
5) In order to remove a magnetization from front, top, bottom and side of CRT, and bottom chassis.
Do not switch off the degaussing coil abruptly. Move the degaussing coil slowly when degaussing.
Note: If switch off the degaussing coil near the set, the set is magnetized.
6) To degauss panel surface.
When switch on the degaussing coil, keep distance between panel surface and degaussing coil to
more than 50cm. Move the degaussing coil vertically near the panel surface. Keep distance of panel
surface and degaussing coil to more than 15mm.
7) 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 )
8) After sufficiently degaussing the CRT, move degaussing coil slowly away from the panel surface while
rotating from corner to center, taking more than 3 seconds. Turn off SW more than 1m away from the
CRT. Degauss again if the unit is magnetized.
9) Push "EXIT" SW to disappear "DEGAUSS OK".
