Errors, Malfunctions, and Safety Features
Within each Base Station is a microcontroller which continuously checks for the state of the
Walk and Don’t Walk status from the Pedestrian Signal Head. In an event the Advisor Guide
sees a conflict, it will turn off all pedestrian crossing indications (vibro-tactile motor, turn off
speaker, and stop any audio output) and remain silent.
