Can the blinking alarms damage backlight?
According to answer #125 at PalmSource Developer Knowledge Base it is not a problem. We have tested prolonged backlight blinking on several devices and have not found any problems. None of our users reported a problem either, so we think it is safe. However, please note that we are not responsible for any damage or consequences. Use this feature at your own risk. If you don’t want the blinking alarms, you can always turn them off by unselecting the top left hand bulb icon.
