Always select the Communicator with a flashing purple LED. This LED behavior indicates the highest level of charge.
All other Communicators in the charging rack should display a solid orange LED, indicating that they are charging normally. After the flashing purple Communicator is lifted from the charging rack, the Communicator with the next highest level of charge will switch from solid orange to flashing purple and should be chosen next.
If no Communicators in the charging rack display a flashing purple LED, please contact Customer Support for assistance.
