Wireless LEDs
There are two Link and Signal indicator LEDs on the front panel.
Figure 5: Front Panel - Wireless LEDs
Link LED
The Wireless Link LED lights solid green when the wireless link is established.
When the Link LED is off, it is an indication there is a problem with either the
terminal link, radio, or with the actual propagation path itself. Check the RF Status
parameters in the System Status screen. The following table lists some of the potential
causes.

Symptom
Possible Problem
Solution
Subscriber terminal is not on or
is malfunctioning.
Verify operation of subscriber
terminal.
The propagation path is
blocked.
Clear path or re-locate
antennas.
The transceiver is mal-
functioning.
Repair or replace transceiver
Antenna has moved and is no
longer aligned with subscriber
terminal.
Re-align the antenna.
Cable between transceiver and
antenna or between transceiver
and terminal not properly
connected.
Properly secure cables.
Power not getting to the
transceiver from the terminal.
Repair or replace terminal.
No wireless link
(Link LED does
not illuminate)
Receiver and transmitter have
been set to different RF
channels.
Make sure both terminals are
operating on the same RF
channel.
Signal LED
When Adaptive Modulation is disabled, the Wireless Signal LED lights solid green if
the system is operating at a BER of less than 1 x 10e-9. The LED flashes if the
number of errors exceeds this limit. If the wireless link becomes very poor, the LED
turns off.
When Adaptive Modulation is enabled, the Wireless Signal LED lights solid green if
the system is operating at a rate equal to or higher than the configured Uncoded Burst
Rate. The LED flashes when the system is operating at a modulation scheme with a
