Backlight Saver Function
• On/Off
When set to [On], the LCD backlight automatically dims according to the specified
conditions described below.
• Saver time
Select a value from “1min, 2min, 5min, 10min, 30min, 1h” (factory default setting is 1h). If the
specified time elapses without any key operation, the LCD backlight is automatically dimmed.
• Restore

The degradation of the brightness and the discoloration of the screen (become yellowish)
