Contrast and Brightness:

Use these controls to adjust the screen brightness to compensate for room
lighting.  Rotate either or both controls clockwise to increase brightness;
rotate counterclockwise to decrease brightness.

Power ON/OFF

To turn on the VGM-220, press POWER. The POWER indicator lights. Press 
POWER again to turn off the monitor.

Vertical Size:

Controls are factory-adjusted and usually do not require further adjustment.

If the display's vertical size is not correct, contact a Radio Shack 
service technician. Or, it you are familiar with this type of adjustment and
want to make the adjustment yourself, use a plastic alignment tool to adjust
the vertical size of each display mode as follows:

   Vertical Size 1:
   Use this control to adjust the vertical size of the display for Mode 1.

   Vertical Size 2:
   Use this control to adjust the vertical size of the display for Mode 2.

   Vertical Size 3:
   Use this control to adjust the vertical size of the display for Mode 3.

CAUTION: If the same characters or graphics are shown for a long time with 
the  contrast and brightness controls set to their maximum positions, part 
of the screen might be damaged.
