Display Brightness and Battery Life
I Display Brightness
You can select a display brightness value in the range of 1 (least bright) to 5 (brightest). The
initial factory default brightness setting is 3.
The brightness level will change to 1 (least bright) automatically if you do not perform any
operation on the calculator for about 30 seconds. Performing an operation will return display
brightness to the level specified by the current setting value.
For details about how to configure the display brightness setting, see “Chapter 12 System
Manager” in the separate Software User’s Guide.
I Battery Life Battery Life
Battery life is affected by the display brightness and backlight duration settings. Battery life
is also affected by how the calculator is used. Using a program to execute a long series of
calculations, for example, will shorten battery life.
