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. The Auto Dimming is effect only when the
power is provided by the lithium-ion battery pack. It will not become effect 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, pressing a key will disable the Auto Dimming
function to resume an ordinary brightness.
• While the Auto Dimming function has been set effect, brightness can be set in one of eight
grades. The default is 3.
During the Auto Dimming function being set effect, 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 input - 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, pressing a key will disable the Auto
Backlight OFF function to resume an ordinary 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 effect, 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.
