Troubleshooting
Link icon the rover’s General Status screen. The base and
rover radio will receive any traffic on the frequency they are
set to causing this icon to appear. This is best done before
setting up the base to transmit data. Any appearance of the
Data Link icon indicates some traffic on your frequency.
1. If there is no jamming, your radio module or radio antenna
may be malfunctioning. There is no way to further isolate
this problem unless you have spares for these
components. Call your local dealer or email technical
support for assistance.
2. If there is jamming:
• Lower the sensitivity of the rover radio using the field
software running your field terminal. The software lets
you change the sensitivity of the rover radio, and you
can also lower the sensitivity of the PDL radio via the
front panel display.
Lower the sensitivity of the rover to medium or low. If
the traffic on your frequency is not strong in power,
lowering the sensitivity of the rover radio may cause
the radio to ignore the traffic. This will not help if the
traffic is caused by a nearby or very high powered
radio.
The disadvantage of lowering the sensitivity is a
reduction in the range of your radio system. A lower
sensitivity at the rover may cause the rover to not hear
the base transmissions as the rover moves farther away
from the base.
• Try another frequency. If you are licensed to operate on
more than one frequency, move to a different
frequency in hopes that the new frequency has less
traffic.
If you have a license for only one frequency, you may
need to find another frequency in your area that is
clear of traffic in order for the system to function
reliably and acquire a license for this frequency if
possible.
