used for the following purposes:
The Intermec Ready-to-Work Indicator

as part of a solution. The Intermec Ready-to-Work Indicator has
three different states: On, Blinking, and Off. When the Indicator
is off, the device is not ready to operate individually or as part of
a solution. When the Indicator is blinking, the device may be
initializing, waiting for external resources, or in need of user
attention. And when the Indicator is On, the device is ready for
use as part of a solution. Also see Chapter 9.
