THE PICTOGRAPH
The PICTOGRAPH gives a pictorial representation of the current setup of the system. It
does this by means of light emitting diodes (LEDs). Each shaded area contains a group of
one or more LEDs and a push button that is pressed to change the setup selection. In the
groups with more than one choice or option, LED’s illuminate one at a time to indicate the
selection. The groups are shown below.
