- If there are other metal detectors installed nearby ensure that they are on different
operating frequencies.

- Following the user manual increase zone sensitivity as well as total sensitivity until it detects
metal that is similar to what you are trying to screen for.
- Metal detectors can detect coins up to 25mm in diameter. If the object being screened is
smaller than that and you try to adjust the machine you may receive multiple false alarms per
screen.
5. A single zone is not alarming
- This is likely caused by the corresponding zone not being sensitive enough. Can be caused by
a zone card not operating as it should. If problem persists at highest sensitivity reach out to a
technician.

- Make sure all cables are seated properly, especially the ones connecting to the back of the
display.
