3.4 Using the Backlight
The PM880 has a backlight that helps in viewing data. Since the backlight
uses more energy, the PM880 has a backlight timer that can be set to
automatically turn the backlight off after a specified time, in order to
conserve battery life. The PM880 also enables you to turn the backlight on
and off manually. Use the sections that follow to operate the backlight.

To manually turn the backlight:
•
On - press any key on the keypad and the backlight will stay on for
the programmed interval. You can also press the power key briefly
(about one-half second) and the backlight will stay on for 30 minutes.
•
Off - press the red power key briefly (about one-half second).
