If the "Light Auto Off" item on the menu screen 3/5 is set to "5 min", the
backlight turns itself off automatically after 5 minutes. When the item is set to
"Cont.", backlighting is turned on and off with the Light key.
When the backlight is used continuously, battery life will be shortened to about
half.
