Troubleshooting in theField 7
File Access Error. The design you selected could not be loaded.
The "current.csd" file in use does not reference the coordinate system required by
the *.cal file in the design folder.
Contact your site supervisor to get the correct "current.csd" file and/or *.cal file.
No band configurable radio found. You must attach a band configurable radio before
using this tool.
You have tried to configure the radio band on a system that does not have a band
configurable radio.

No coordinate system could be found for this design
All GNSS-based systems need to have a valid coordinate system loaded onto the
GNSSreceivers. If you attempt to load a design that does not contain a coordinate
system, you will experience one of two outcomes:
l If the previously loaded coordinate system was created manually (a *.cfg file),
then press \ or = to load the coordinate system.
l If the previously loaded coordinate system was created automatically (a *.acs
file), then you cannot use the design, and it will not be loaded.
In either case, tell your site supervisor that you have been given a design with no
coordinate system.
No data
The system is not receiving any information from a sensor.
Try one of the following actions:
l Check the cable connections.
l Inspect the sensor for physical damage.
l To check that all the required components are responding, use the procedure in
7.3 Running system diagnostics.
l Switch off the power and then switch it on again.
No devices were detected on the CAN bus
The system uses a CAN bus to pass data and commands between its components
(for example, the control box and a sensor). If this message is displayed, the
