device is incorrect
Short circuit with
board or antenna
Remedy
1. Align antenna to the target's travel direction.
2. Direct antenna away from moving objects that are
not intended to be targets (including cooling fans
and other rotating objects).
3. Direct the antenna away from electrically noisy
circuitry (such as strong lighting, neon lights, and
exposed clock oscillators) and multiplexed displays.
4. Mount the antenna on a stable surface. If the
mounting moves, the motion is added into the
displayed speed.
See above remedy if you believe the problem is
with the antenna. If you believe there is something
wrong with the power connection, go to the
section on power/communications to see if the
board and connectors are placed correctly. Also,
make sure the processor board is:
1. Mounted in an area that is free from exposure to
liquids.
2. Mounted where interference from other circuits is
minimized.
3. Mounted where the board is not in the beam of the
antenna.
See sections Processor, Power/Communications, and
RS-232C commands to make sure RS-232C
communications are set up correctly.
Disconnect the board and antenna from the power.
Send in the system for repair.
