Optimizing RF Reception
33
The signal LED indicates the strength of the signal by measuring the signal-to-noise ratio (SNR).
SNR indicates received signal strength relative to background noise. The ratio is usually measured
in decibels (dB). Thus, the higher the SNR ratio, the better the communication.
The table below describes the EasyST signal LEDs with regards to SNR values.

Average SNR (dBm)
All LEDs are off
SNR < 5
First left-most LED is on
5 <= Avg. SNR < 9
Two left-most LEDs are on
9 <= Avg. SNR < 12
Three left-most LEDs are on
12 <= Avg. SNR < 16
Four left-most LEDs are on
16 <= Avg. SNR < 22
signal Green
Five LEDs are on
22 <= Avg. SNR
