(2) Keep the demagnetization coil at a distance of more than 1.5 cm from the CRT screen and the main unit during use. (3) When demagnetizing the CRT screen, hold the demagnetization coil perpendicularly to the CRT screen.
  • Page 8 3.2.2 DEMAGNETIZING THE CRT SCREEN (1) While holding the power button of the demagnetization coil, move it to approach the CRT screen area that has color irregularities. (Keep the demagnetization coil at a distance of more than 1.5 cm from the screen.) (2) From the area with the colour irregularities, move the demagnetization coil as if drawing a spiral toward the center of the CRT screen.
