You can manually degauss (demagnetize) the monitor, change the menu position, set the power saving delay time, and lock the controls.

Resetting the adjustments
This monitor has the following three reset methods. Use the RESET button to reset the adjustments.

Technical Features
Preset and user modes
When the monitor receives an input signal, it automatically matches the signal to one of the factory preset modes stored in the monitor�s memory to provide a high quality picture at the center of the screen. (See page i for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the digital Multiscan technology of this monitor ensures that a clear picture appears on the screen for any timing in the monitor�s frequency range (horizontal: 30 � 107 kHz (GDMF400) or 30 � 121 kHz (GDM-F500), vertical: 48 � 160 Hz) . If the picture is adjusted, the adjustment data is stored as a user mode and automatically recalled whenever the same input signal is received.

Troubleshooting
Before contacting technical support, refer to this section.

If thin lines appear on your screen (damper wires)
The lines you are experiencing on your screen are normal for the Trinitron monitor and are not a malfunction. These are shadows from the damper wires used to stabilize the aperture grille and are most noticeable when the screen�s background is light (usually white). The aperture grille is the essential element that makes a Trinitron picture tube unique by allowing more light to reach the screen, resulting in a brighter, more detailed picture.

Degaussing the screen
The monitor is automatically demagnetized when the power is turned on. To manually degauss the monitor, first move the joystick up or down to select (MANUAL DEGAUSS). Then move the joystick to the right. The screen is degaussed for about 3 seconds. If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result.
