Backlight Auto Dimming
The control panel can be used to set up whether or not the auto dimming function will be used and
the waiting time until when dimming begins. Auto dimming is enabled only when the power is
provided by the lithium-ion battery pack. It will not function when an external power supply is
used.
• If the terminal is left over in idle state - absolutely no key input - while the power is turned on,
the backlight will be automatically dimmed to save the power after a given period of time has
been elapsed.
• When the terminal is in the auto dimmed state, a press of key will disable the auto dimming
function to resume the brightness.
• While the auto dimming function has been set enabled, brightness can be set in one of eight
grades. The default is 3.
During the auto dimming function being set enabled, brightness cannot be set any brighter than
the brightness illuminated by the backlight. The defaults are “Enable the auto dimming function”
and “1 minute” for waiting time period until when the auto dimming function activates.
Auto Backlight OFF
The control panel can be used to set up whether or not the Auto Backlight OFF function will be
used and the waiting time until when the Auto Backlight OFF function activates. The Auto
Backlight OFF function is operable for both when the power is provided by an external power
source and when it is provided by lithium-ion battery pack.
• If the terminal is left over in idle state - absolutely no key - with the power being turned on,
the backlight will be automatically turned off to save energy.
• When the terminal is in the Auto Backlight OFF state, a press of key will disable the Auto
Backlight OFF function to resume the brightness.
• While the power is being provided by lithium-ion battery pack and both the auto dimming
function and the Auto Backlight OFF function have been set enabled, either one of the
functions with preset time period shorter than the other will have the priority. The default is
“Enable the Auto Backlight OFF function” and “5 minutes for the waiting time” until when
the Auto Backlight OFF function activates.
Rotating Display
The rotate display function for rotating the screen at 90, 180 or 270 degree is supported.
• The Common Device Control Library can be used to set up in the application.
• ChangeDisplaySettingEx() API function can be used to set up this display rotation feature
in application.
See Microsoft Help for details about ExtEscape() and ChangeDisplaySettingEx() API
