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, or using it
under cold conditions shortens battery life.
The following shows how backlight use affects battery life under controlled test
conditions.*
* Test Conditions
• Temperature: 25°C
• “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.
• The above battery life values are based on Panasonic CR2032 batteries.
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.
• The low battery message may appear even when battery power is not low if
you turn on the EL backlight under cold conditions. We recommend that you
do not use the EL backlight under cold conditions.
