JVC BM-H1900SU, BM-H1310SU manual Basic Operation, To demagnetize the picture tube

BASIC OPERATION

1. To turn the power on: Push the POWER switch.

The POWER indicator glows green. The mode and color system of an input signal are automatically discerned and displayed on screen for about 3 seconds. To turn off power, push the POWER switch again, and the POWER indicator goes off.

2. To select the input:

Push an INPUT SELECT switch.

Push VIDEO A, VIDEO B, RGB/COMPO(SDI) or Y/C. The mode and color system of a selected input signal are automatically discerned and displayed on screen for about 3 seconds.

3. To adjust the audio level:

Turn the VOLUME control to the right to increase the level, or to the left to decrease the level.

To demagnetize the picture tube

After positioning near the monitor a speaker (non-magnet- shielded) or other equipment that generates a strong magnetic field, or after relocating the monitor, color patches could appear in the picture due to magnetization of the picture tube. If this occurs, push the DEGAUSS switch to demagnetize the picture tube.

NOTE

●This function is not effective if activated a second time after a very short time has elapsed. When degaussing must be repeated, proceed after at least 10 minutes have passed since first degaussing.

●The optional wireless remote control features a DEGAUSS key.
