12.2.12 Error Messages
If an error occurs during data acquisition, an error message will appear in the bottom left section
of the data acquisition screen. Note the message number, exit the program and turn off the
Digital Video Logger. 
Make sure the cables are not damaged and that all cable connections are tightly secured.
Sometimes vibrations cause the cable connections to loosen just a bit and break contact and this
can cause errors.  Disconnecting cables and reconnecting them may provide a better contact
and solve the problem.  Also check and make sure the battery is adequately charged. Turn the
Digital Video Logger back on and try running the system again.
For more information on Troubleshooting the system, see Section 13: P.112.
