Press the Power button at the bottom right of the screen or the ⏻ key on the remote. The LED indicator turns solid white when the device is ready.

How do I adjust the monitor volume?

Use the Vol+ and Vol- keys on the remote, or go to OSD menu > Audio to adjust the volume with the slider.

What should I do if the touch screen stops responding?

Make sure the screen is not exposed to direct sunlight. For an external connection, ensure the USB cable is properly plugged into the Touch port on the back. Restart the device if necessary.

How do I update the firmware?

How do I activate energy saving mode?

In Settings > System > Power, select Standby Power Mode and choose Eco. This reduces consumption in standby. You can also set Auto Off after a period of inactivity.

What should I do if the remote control stops working?

Check that the batteries are inserted correctly (2 x AAA) and are not depleted. Ensure there is no obstacle between the remote and the IR sensor (distance < 8 meters, angle < 30°). Replace the batteries if necessary.
