Abstract
A system and method are provided for presenting an apparatus history using a light emitting device (LED) log. The method provides an apparatus user interface (UI) including a plurality of LEDs and presents an LED log. The LED log emits light as a chronological sequence of a first LED pattern followed by a second LED pattern. Each pattern includes the illumination of at least one LED, and the first pattern is different from the second pattern. In response to the LED log, an apparatus condition is communicated. In one aspect the first pattern includes a first number of illuminated LEDs and a second pattern including a second number of illuminated LEDs, different from the first number. The patterns can also be distinguished by color, on-times, and off-times.
