Hello and welcome to our EMPSALE store! Ferrari crocodile : When the game machine is working can emit high frequency electromagnetic waves,the game machine on the motherboard on the chip, using the game machine disturbance game board, a coin collector, on key points, and high field RF,signal can penetrate inside the machine, wire, resistor, capacitor, chip, IC SCM,transistors, etc., signal interference on integrated circuit after receive points or coin, the game machine will automatically divide or coin, electric appliance is composed of electronic components, so that electrical engineers headache is the most special high frequency ultra high frequency electromagnetic interference, electromagnetic interference, this problem is now and in the future to overcome the problem, the problem is the biggest flaw of the game machine.
