[BACKLIGHT], the Backlight will remain on
for as long as you continue to use the Organizer, until you
have not typed any key for 1 minute. This is useful if you want
to enter or access some information that will take longer than
1 minute.
The Backlight may remain on for less than 1 minute if the battery

Since the Backlight drains power from the operating
batteries, excessive use of the Backlight will significantly
reduce your battery life.
*
Continuous use of the Backlight will, over time, lead to
gradual loss of brightness.
