Receiver

The radio constantly measures the received signal strength (RSSI) of the receiver. The Signal Threshold setting determines the received signal level above which the search for the radio messages is active. If the threshold is set too low (the CD LED is ON constantly), the receiver catches surrounding noise and constantly tries to receive messages. In such a case, the actual data transmission might get missed and remain unnoticed. If the threshold is set too high, the weak data transmissions will be rejected although they could be otherwise receivable.

The radio shows the RSSI of the last received message in dBm units.
