• searching for a Base Station - A complete sweep of all frequencies takes about 30
seconds. The display shows which frequencies may be Base Stations. A search is
started when any of the following occurs:
• the modem boots up, either due to a hard (power) reset or software reset,
• no Base Stations are found during the last frequency sweep, so that the
modem cannot register with any Base Station found during the last sweep,
• the modem has received no signal from the Base Station in the last two
minutes. This indicates that the Base Station or radio link is down.
• attempting to register with a Base Station - When a frequency sweep has been
completed, the modem attempts to register with the Base Stations in the order of best
signal down to poorest. The modem may not register with a Base Station for a number
of reasons, in which case the modem attempts the next Base Station in the frequency
list. If the modem cannot register with any Base Station, contact the network operator.
The reasons a modem may not be able to register with a Base Station include:
• The modem is not authorized to register at that Base Station,
• The signal detected is not a valid Base Station.
• registered with a Base Station - This state occurs when the modem has a frequency
and has successfully registered with a Base Station. At this point, the modem can
provide a link to the Internet through the Base Station.
An example of the Radio Link Status display is shown below.

The Signal Strength and Signal Quality graphs and values are Figures of Merit (FOM) and are
interpreted using the tables below. The goal for aligning the antenna is a Signal Strength of 5
or better and a Signal Quality of 4 or 5, if possible.
