Backlight Auto Dimming
The Control Panel can be used to set up whether or not the Auto Dimming function is used and
the waiting time until when dimming begins. Auto dimming is set effect 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 disables the auto
dimming function to resume the brightness.
• While the Auto Dimming function has been set effect, the brightness can be set in one of eight
grades. The default is 3. During the Auto Dimming function being set effect, the 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 the 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 the power.
• When the terminal is in the Auto Backlight OFF state, pressing a key disables the Auto
Backlight OFF function to resume the brightness.
• While the power is being provided by the 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.
