Product / Models Affected:

CCU2EN, EZ Communicator Navigator (EN2)

Situation:

Some customers have reported a stuck ped call where the CCU2EN ped call light is on, indicating a self-test failure, but there are no flashing green ID LEDs

Solutions:

Investigation shows that this can only happen if an internal variable value gets altered unexpectedly to an invalid value. CIP firmware version 4.07 addresses this without regard to the actual cause. The variable is now screened continuously and corrected as needed.
