7.1 LED Indicators
The LED status indicators are an important troubleshooting tool and
should be checked whenever a problem is suspected. Table 2 on page 7
describes the function of each status LED.

Table 6 provides suggestions for resolving system difficulties that may
be experienced in the radio system. If problems persist, contact the fac-

Difficulty Recommended System Checks
Unit is
inoperative.
a. Check for the proper supply voltage at the power
connector.
b. The transceiver’s internal resettable fuse may have tripped.
To reset it, momentarily remove and re-apply power to the
radio.
Interference is
suspected.
a. Verify that the system has a unique network name. Nearby
systems with the same network name will cause
interference.
b. If omnidirectional antennas are used on Station Adaptors,
consider changing to directional antennas. This will often
limit interference to and from other stations.
No synchronization
with Access Point,
or poor overall
performance.
a. Check for secure interface connections at the radio and the
connected device.
b. Check the antenna, feedline and connectors. Reflected
power should be less than 10% of the forward power
reading (SWR
≈2:1 or lower).
