RF5xx Transmitter Status Codes (COdE) Explained

Under certain conditions your RF5xx Transmitter might display a Status Code on the LCD screen which takes the form of the word ‘COdE’ followed by either a 3- or 4-digit alphanumeric sequence. These Status Codes can help in diagnosing the reason why a Transmitter might be failing to transmit data to the Gateway.
