To check if your base station is working, open the electronics box & check to see if the status light (shown in red below) is flashing green. If it is flashing green, your base station is working.
If you have just turned your base station on, you will seered and green LED indicators on the left side of the circuit board as it connects to the network (outlined in yellow in the picture above). The red light will flash progressively faster as it searches for & finds a network to use. Both the green light & red light will turn off once the base station connects to the network. Then, if the status light (shown in red above) is flashing green, your base station is working.
