The first line shows the percent of successful transmissions. As long as you are
getting at least 90%, you will have excellent results in the location tested.
If you don’t get the minimum results shown above:
1. Try hanging the Base Station upside down or tilted toward the
area of usage – this alone can double the effective range.
2. If using a European terminal, try a different channel. You may
find less interference on another channel. There are several to
choose from, only try 1 or 2 others. This does not apply to the
US Terminal, because all channels use the same 25
frequencies, just in a different hopping order.
3. Try locating the Base Station closer to the area of difficulty.
Remember that moving the Base Station will require you to
recheck the other locations already tested.

If none of the above works, you will have to consider using a Relay.
Relay Stations
Keeping all of the above factors in mind, using Relay Stations can increase
your area of coverage by 5 times. Relays work like a remote antenna,
passing data to the Base Station via cable instead of radio frequency. Base
Stations are used as Relay Stations by changing the jumpers inside. See
Appendix A
for details.
Relay Stations are attached to the Base Station using a cable that connects
from the Base’s RELAY port to the Relays’ RELAY port. When you order
a Relay Station, you receive a 3-foot test cable with it. Although Relay
Stations will increase your range of operation, they will also add about 1⁄2
second to the response time.
How Relay Stations work…
It helps to know how Relay Stations work before you add them to your
system. Although Relays increase your operational range, they also slow the
response time of your system. In order to use Relays, the Terminal must be
configured to acknowledge that Relays are present. This is done using the
