Work or instability, so in order to make the anti-theft device for shops stable and sensitive to normal work, the installation of the anti-theft device for shops before the site in advance to eliminate the interference can interfere with the source specific requirements and precautions.

The 220V AC used by all antennas must be all-electric, and the neutral and live wires must be in the same position (left zero line and right fire line).

2. Testing and debugging of anti-theft device for shops
Before debugging the anti-theft device for shops, set the receiving sensitivity potentiometer in the chassis. Usually, the small hole is used to align the center of the cavity of the antenna.

Any untested antenna can short-circuit the receiving coil to ensure that the unoperated antenna does not cause interference.
