Setting Abo Time - Casio IT-2000W Technical Reference Manual

Setting ABO Time

The ABO (Auto Backlight OFF) function is used to automatically turn off the backlight if neither
key entry nor touch-panel entry is permitted for a certain period of time. This function is used to
set the ABO time. Enable ABO by selecting a number between 1 and 15, which corresponds to
a period of between 20 seconds and 5 minutes.
