The RSSI screen displays the signal quality parameters of the received RF signal. The
current display is in dBm re 50 Ω and 1 mW, and the reading is typically accurate to
within ±2 dBm between –120 dBm and –50 dBm, if the radio has been correctly
calibrated. For example, –90 dBm is a strong signal and –130 dBm is no signal.
The RSSI screen will also display the Bit Error Rate (BER) for slots one and two. RSSI and
BER are typically used to indicate signal quality.
