Palm m505 and m500 Handhelds Backlight Utility

Posted June 14, 2001
Palm has made available a new add-on software application for the Palm m505 and m500 handheld computers that allows users to quickly and easily set the backlight to "always on" status. This application is specifically for customers interested in having more control over screen brightness.
The application is designed for Palm m505 and m500 handheld users who prefer to use their handheld with the backlight on under all or most conditions. When installed on a Palm m500 or m505 handheld, the new backlight application simply "remembers" the last backlight setting. To set "always on" backlight status, a user turns on the device and then turns on the backlight as usual by holding the power button for 2 seconds. The user then turns the device off while the backlight is still on. The next time the handheld is powered on, the backlight automatically will come on. To turn off the backlight, the user holds down the power button for 2 seconds and the "backlight off" status will be remembered for the next use.
With this application, handheld users can gain more control over the brightness of their m500 and m505 handheld screens. They have the flexibility to customize their backlight settings for use in low-light conditions.
Using the backlight on a regular basis draws additional battery power. To conserve battery life, Palm recommends turning off the backlight when it is not needed.
