Troubleshooting
Step 1. Is the
Receiver Fitted
with the
Appropriate Radio
Module?
The radio module used should be compatible with the radio
transmitter used at the base. Several sub-bands and channel
bandwidths are available for the radio (see Communication
Modules and Associated Antennas on page 3).
1. If you are using the right module, go to step 2.
2. If you are not using the right module, turn off the receiver
and replace the module with the right one. You then need
to restore the default settings in the receiver (by pressing
the Log+ Scroll+ Power buttons simultaneously on the
front panel) so the receiver can recognize and use the new
module. If using the right module does resolve the
problem, go to step 2.
NOTE: There is no particular action required to power up
the radio module other than to power up the receiver. This
automatically applies power to the radio module.
Step 2. Is the
Radio Antenna
Connected to the
Radio Module?
The radio module cannot operate properly without an
antenna. Make sure the antenna is connected to the radio
module.
1. If the antenna is not connected, connect the radio
antenna (provided in the radio receiver kit) to the radio
module. Ensure that the connection is secure. If the
problem is not yet resolved, go to step 3
2. If the antenna is connected, ensure the connection to the
radio module is secure. If the problem is not yet resolved,
go to step 3.
Step 3. Are the
Rover Radio
Settings
Compatible with
those of the Base
Radio?
The rover radio must use settings that are compatible with
those of the base radio, in order for the rover to receive
corrections from the base. (This means you are supposed to
know the currently used base radio settings.)
1. Check the radio settings in the rover:
Use the field software running your field terminal to check
the frequency, protocol and “Over the Air” baud rate used.
2. If the rover radio is set properly, go to step 4.
Step 4. Is the Line
of Sight Between
the Base and the
Rover Antennas
Obstructed?
Although radios are fairly robust, an excessive amount of
obstructions can block out the signal.
1. If the line of sight is not obstructed, go to step 5 below.
2. If the line of sight is obstructed:
• Move to a less obstructed location. In order to test if
the system is functioning properly, move to a location
that does not have an obstructed view between the
base and rover radio antennas.
