 ABOUT EXTERNAL CONTROL

This monitor is provided with an external control terminal.

The function is controlled with H and L (short-circuit/open with the 15th pin GND)

Note:

● The ASPECT RATIO or INPUT function can be controlled via the REMOTE terminal by setting ASPECT REMOTE or INPUT REMOTE to ON in the <SET-UP MENU> screen. (Refer to pages 9 and 10.)

Connections

Connect (short-circuit) the 15th terminal (GND) to the 2nd or 10th terminals in the 3-line 15-pin D-sub connector. Do not conne	ct
other terminals.

The following are not malfunctions:

● When a bright still image (such as a white	cloth) is	displayed for a long period, it may appear to be colored. This is due to t	he
structure of the cathode ray tube and will	be deleted	when another image is displayed.

●You experience a mild electric shock when you touch the picture tube. This phenomenon is due to a normal buildup of static electricity on the CRT and is not harmful.

●The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an abnormality appears on the screen as well.

●If two or more monitors are operated next to each other, their images may shake or be distorted. This phenomenon is due to mutual interference; it is not a malfunction. Move the monitors away from each other until the interference disappears or turn the power off on any monitor that is not being used.
