LED Indicators
The LED indicator light is located on the rear of the display near the keypad. The
following table explains what the different colors and blink patterns mean.
Using the Display in Portrait Mode
When using the display in the portrait position and looking at the rear of the display,
it should be rotated according to the arrow stickers on the back of the display. This
will allow for proper ventilation. Then select the OSD rotation of landscape or portrait
on the OSD menu (MAIN MENU > BASIC > OSD ROTATION).
Caution: Improper ventilation may shorten the life of the display.
