and the Air LED of the base station also turns orange as both units send and receive data from each
other. Orange is the normal Air LED color.
The color of the Air LED during this step indicates the following conditions.
Note: If antennas are placed too close together (< 2 m), the strong transmit signal can saturate the receiving
unit. Fine-tune antennas by changing antenna orientations until the Air LED is orange.
Next, you will test the link’s basic ability to carry data.
