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). The higher the SNR ratio--the better the communication.
The table below describes the EasyST signal LED with regards to SNR values:
LED Color Status Average SNR (dB)
All LEDs are off Avg. 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
