3. OPERATION: USER CONTROLS

Important:

The best way to adjust and control the display is by using MediCal, which displays the ideal test patterns for correct adjustment. However, in case you do not dispose of MediCal, you can control and adjust the display by means of the built-in On-Screen Display (OSD).

3.1 Switching on / off

Power on/off

Press the Power button {11} on the rear panel to switch on the display. The green LED at the front is off when the display is operating.

If the display starts up with no image and the green LED {3} on, it is in stand-by. This is the case when the display was powered down while in stand-by.

Manual stand-by

To put the display in manual stand-by mode, press the control knob {2} shortly. As a result, the green LED is ON continuously.

Note: You cannot switch the display in manual stand-by when the on- screen display (OSD) is visible. In that case, first exit the OSD, and then press the control knob to switch to stand-by mode.

To activate the display from stand-by mode, press the control knob {2} again. As a result, the LED is switched off again.

Automatic power saving system (DPMS)

The power saving system, if switched on, can power down the display when you don't use the computer that produces the video and sync. signals for a while. In that way, the system reduces the display's power consumption.

While the display is powered down, the picture tube will be blanked, and the green LED on the front is blinking. In the last DPMS mode, the LED will be on continuously.

The power saving system is switched off when the display is produced. It can be switched on by a qualified technician.

Note: The power saving system can only work if the connected imaging board supports power management.

For more details, please read Appendix A, "Background information".
