into the standby status.

When the Power On Delay function is activated, the power lamp blinks in orange (at about 1 second intervals).

If the setting is set to “0” (factory default), the function gets disabled and the lamp won’t blink.

The Power On Delay function enables a time delay from the turning-on of power till the display of screen, and the set-
ting can be set in 1 second increments up to 60 seconds.

(Temperature 
abnomaly)

The message “TEMPERATURE” blinks at 5-second intervals in the corner of the screen (Lower left corner at the fac-
tory default), and it indicates an abnormality in the internal temperature.

*

It operates only when “FUNCTION” - “TEMPERATURE ALERT” is set to “OSD&LED” or “LED”.

When it is “OFF”, it does not blink. (Factory default: “LED”)

*

Even when “FUNCTION” - “LED” is set to “OFF”, the setting of “TEMPERATURE ALERT” takes effect.

At the same time, the brightness is forcefully reduced by the internal processing of the LCD monitor.

If it is left in the above state and the internal temperature increases further, the monitor shuts off automatically.  (Goes 

into the standby mode.)
By cycling the main power or turning off and on the power by the remote controller,  the screen can be restored to its 

original state temporarily.  However, it goes back to the standby status soon unless the cause of the temperature 

increase is removed.

Red lamp is flashing.

The message “STATUS” is displayed in the corner of the screen (Lower left corner at the factory default). This indi-

cates an abnormality occurring with the hardware. 
Based on the sensor monitoring data, the defective board/ unit needs to be replaced.

*

It operates only when “FUNCTION” - “STATUS ALERT” is set to “OSD&LED” or “LED”.

When it is “OFF”, it does not blink. (Factory default: “LED”)

*

Even when “FUNCTION” - “LED” is set to “OFF”, the setting of “STATUS ALERT” takes effect.
