About the EL backlight
About the EL backlight
• This unit is equipped with an EL backlight that allows easy viewing of display
contents in a theater, or anywhere else where lighting is dim.
• Note, however, that frequent or extended use of the EL backlight shortens
battery life.
The following shows how backlight use affects battery life under controlled test
conditions.*
* Test Conditions
• “Battery Life” is the number of hours before battery failure when the unit is left
on with 5 minutes of a processing operation and 55 minutes of continuous
display only (no processing operation) per hour, plus the backlight operation
described below.
• “Backlight Operation” is the number of minutes the backlight is turned on per
hour during the display only (no processing operation) period.
Important!
The EL backlight may fail to operate when battery power is low, in order to
conserve remaining battery power and protect data stored in memory.
