Troubleshooting
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 $PASHQ,RDP,PAR or FAST Survey (

field, ) 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.
• If this is not possible, move to higher ground or a
location where there is less obstruction.
• If, after moving, the rover radio begins to receive data
from the base, then the previous location is too
obstructed from the base. You will need to either raise
the base radio antenna higher, or move the base to a
location with less obstruction between the base and
rover radio antennas.
3. If the problem is not yet resolved, go to step 5.
