Hello. This is GunPower. 

When the point of impact is made incorrectly in symmetry for all four ways,

in the case of 24 inches and 50 inches, please go to the Settings of SMT using an arcade box or mouse, 

uncheck the ‘SENSOR REVERSE’ function and save, 

while in the case of 32 inches, please do the opposite by checking the ‘SENSORE REVERSE’ and then save. 

Thank you.
