LED is only on when there is an issue with either signal strength or pairing mode. There are two LED Colors:
• Blue - Signal Strength. A blue LED indicates the signal strength is low or out of range. When the blue LED light is off it indicates signal strength is good.
• Green - Pairing. A green LED light indicates the unit is in pairing mode.
Note: If there are more than two conditions active simultaneously, for example low battery and weak signal, the LED will alternate back and forth blue and red in one second intervals.
