Switching VGA and QVGA
The Windows Mobile OS integrated in devices including the Casio IT-800 cannot switch the
display mode, from VGA to QVGA and vice versa, due to Microsoft requirement. This limits that
the display resolution with the OS is VGA mode only.
However, the Windows Mobile OS features extended display function which offers various
display modes detailed in the table.

Backlight Brightness
• Brightness of the backlight can be adjusted at the Control Panel, or using the relevant
functions of the System Library.
• Brightness setting can be made in one of nine grades for power source either when the power
is provided by an external power supply (by AC Adaptor connected via cradle, or AC Adaptor
directly connected) or when the power is provided by the installed lithium-ion battery pack.
• Brightness setting can be made in application by using ExtEscape()API function.
• If the brightness is set to 1 (minimum), the backlight is turned off.
• With the power source by the installed lithium-ion battery pack, the system automatically
controls the brightness at 50% level to curve power consumption. This does not require the
running application to aware of the brightness control.
• The default is 9 (maximum) when an external power source is used or 7 when the lithium-ion
battery pack is used.
