b. If all parameters in the RF gate performance section remain orange or red, there is an active
interferer (another device that transmit radio waves around the 8.2 MHz RF spectrum, like
another EAS system, an engine or a power supply). Please continue at the 'active interferer'
section.
Coupling problem
Coupling problems are caused by objects that act as a label to the RF system. For example metallic
doorframes, metal checkouts, cabling: everything that runs in a loop and is metallic.
To solve these problems, there are a few things you can try:
Tighten screws in the metallic construction. This might work for checkouts or customer guidance rails.
Try to interrupt the metallic loop. This can be done by using non-metallic parts inside those loops, or to
make a cut in them.
Create a shortcut in the metallic loop, to make it smaller. In this way it will resonate at a different
frequency.
If the above solutions don't solve the problem, you can decrease the sensitivity of the system. This can be
done by ticking the 'reduced sensitivity' button in the RF Advanced Config.
If a decreased sensitivity doesn't work, and there is only one type of label or tag in the store, you
also have the option to increase the 'receiver delay', in steps of 3 dB.
If these things don't solve the problem, please contact support.
Active interferer
The first step is to try to locate the source of the active interferer. You can do this by unplugging electronic
devices around the gate (or move them away), and see if the parameters in the 'RF gate performance' section
improve, or when the average height of the spectrum is reduced. If this is the case, you have identified the
active interferer.
When the active interferer is known, the following solutions are possible:
Try to move the active interferer away from the gate as far as possible.
Try to apply filters around the cabling of the active interferer.
Shield the active interferer with aluminum foil of at least 0.05 mm (2 mil.).
If the above solutions don't solve the problem, you can decrease the sensitivity of the system. This can be
done by ticking the 'reduced sensitivity' button in the RF Advanced Config.
