nOperation mode

When the monitor is turned on for the first time after being

shipped from the factory, the operation mode setting screen

will be displayed. Set it to MODE1 or MODE2.

MODE1 ... OFF IF NO OPERATION is set to ON, and

STANDBY MODE is set to LOW POWER. (These

settings can not be changed.)

If there is no operation for 4 hours or more, the

monitor automatically enters standby mode. Power

consumption in standby mode is also minimized.

MODE2 ... Will perform standard operation.

OFF IF NO OPERATION is set to OFF, and

STANDBY MODE is set to STANDARD. These

settings can be changed.

Even after being set, changes can be made using

OPERATION MODE, located in the menu of the monitor. (See

OPERATION MANUAL.)
