Display Brightness And Battery Life - Casio fx-CG50 Hardware User's Manual

Display Brightness and Battery Life

k 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.
Display brightness will change to a level that is darker than 1 (least bright) 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.
k 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.
