Possible Solution
Make sure the battery or AC adapter is properly
connected. See section 2.11.
Check signal lines and terminal connections. Connections
must be free of corrosion. Signal lines should be
undamaged and free of sharp bends and twists. Signal
paths should avoid potential sources of noise (high
voltage and electromagnetic interference). You can also
connect the Shield ground to Earth ground to minimize
sensor noise pickup.
Possible Solution
Verify that the firmware update file is a
later release than the currently installed
firmware.
