Operator Controls
Located on the front bezel of the LCD are the operator controls. The operator controls (from
bottom to top) consist of On-Off, Red Power On LED, Brightness Controls and On-Screen
Display (OSD) controls.
Power Controls
When power is first connected to the unit, the unit defaults to the Off state. The Power On-Off
button is marked with the I/O symbol. Momentarily pushing this button will turn the LCD on or
off. In the lower left corner is a Power On indicator, a red LED. Once the unit is connected to a
power source, pressing the power button once will turn the unit on and the LED will indicate
that the unit is ready. Pressing the power button again will turn the unit off.
Brightness Controls
Located next to the Power on LED are two buttons for controlling the brightness of the display.
The button with the large sun symbol, when either repeatedly pressed or when held for several
seconds, will cause the brightness to decrease. The very brightest setting is for operation
when the ambient light is at a maximum. This can be stepped down in increments to the
lowest setting, which is just above total black and is suitable for use in very subdued light or
night operations. The unit will automatically revert to a mid-range setting when power is turned
off.
Setting Brightness
As a rule, adjust the brightness of the display to the lowest possible setting for a given set of
conditions and display characteristics. Doing so will provide for the best viewing of the image,
will extend lamp life of the backlight, reduce the power required by the LCD, and reduce the
power consumption and internal heat of the display.
