Abstract
Disclosed are embodiments of methods, systems, and apparatus for varying the illumination in a data reader or data reading system. In one embodiment, an illumination source for illuminating an optical code on an item is provided. A control may also be provided for activating the illumination source. The illumination source may be configured to undergo an illumination sequence in response to an activation of the control. The illumination sequence gradually increases the intensity of the illumination source perceptible to a user over time so as to reduce the user's fatigue and/or irritation associated with the illumination source.
