About the EL backlight
•The PV Unit is equipped with an EL backlight that allows easy viewing
of display contents in a theater, or anywhere else where lighting is dim.
• Tap the icon to turn on the EL backlight and illuminate the display screen.
•You can use the procedure on page 23 to specify how long the EL backlight stays on (approximately 15 or 30 seconds).
•Note that EL backlight operation consumes large amounts of electrical power and can greatly shorten battery life.
•Note 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*. For comparison with the values below, battery life is normally approximately 180 hours of continuous display in the Contacts Mode when no backlight operation is performed.
Backlight Operation | Battery Life |
|
|
3 minutes per hour | Approximately 80 hours |
|
|
15 minutes per hour | Approximately 35 hours |

* Test Conditions
•“Battery Life” is the number of hours before battery failure when the unit is left on (5 minutes of a processing operation and 55 minutes of continuous display only (no processing operation) per hour in the
Contacts Mode, plus the backlight operation described below). The above values assume ambient temperature of 20°C, starting with a fresh set of new batteries.
•“Backlight Operation” is the number of minutes the backlight is turned on per hour during the display only (no processing operation) period.
•Be sure to use alkaline batteries. Manganese batteries provide very short battery life.
