A
Verify the radio link. Check the received
signal level. The center LED on the
EUM is flashing rapidly,
or ON solidly. Received signal is
greater than -80 dBm,
which should provide
enough margin for stable
performance. Go to B.
• If there is no LED activity, confirm the
radio frequency.
• Use the RSSI or Configuration Utility to
measure signal strength.
• Check antenna connections.
• Improve antenna pointing and/or
location.
