A.1 Problems/Solutions
Problem: No power LED.
Solution: Check the power connections.
Problem: No radio link.
Solution: The radio is looking for its matched partner. If both units are powered
on and the Power LEDs are active, they may be too far away to create the radio
connection. Try other locations to get the best range when they are oriented to
point directly at each other with antenna elements oriented in the same plane (i.e.,
vertically or horizontally).
Problem: Radio link on but quality indicator is low.
Solution: The units may be too far away from each other to create a good radio
connection. Try other locations that may have a less obstructed path, or try reori-
enting the antennas.
Problem: Ethernet LED is not lit.
Solution: Check your network connections.
