Justen from CLS called and said the remote was showing Comm Error. Talking with Tomas, it is the data being sent from receiver to the remote (transmitter) for the display. Check the connection at the receiver with the red antenna for loose or corrosion at the connection. Also, check inside the remote there is an antenna that can come loose or fall off. If all looks good, need to replace both receiver and transmitter.
