2.2 System States and LED Indications
The following information relates to the figure below showing LED Flash Patterns and Coherence.
The system state is indicated by either a green or a red LED. The red LED is used for indicating the battery
state exclusively, whereas the green LED indicates all other system state information.
On theleft side in Figure 2-1, all possible state transitions are shown with the associated LED flash
patterns. Each rectangle represents a time slot of two seconds, which is infinitely repeated. Green/red
indicates LED on, while white indicates LED off. The green LED is shown above the red LED pattern. The
exact ON times are listed in Table 2-2.
To the right, LED flash patterns associated with events are shown. These are only generated once.
2.3 System Events and Audio Indications
Several significant system events, and a few system states, are indicated by audible indications. In the case
of events, the audio indication is only played once (as for the LED indications), whereas system states are
identified by repeated audio indications.
In Table 2-3, all audio indications are listed and defined. In addition to the actual frequencies and duration,
an intuitive description of their appearance is included. This should give a good idea of how each
indication sounds since just listing the frequencies may be a little too abstract for practical purposes.
