Equites thank you so much you saved my starblade

ok 3 small problem
1 the chair keep on rumbling like crazy out of control so i had to plug it out
2 the screen is a bit out of focus
3 and the gun is not centered i should turn it slightly to the right so i can center my shooting
and what up with these annoying flash lamp that keep on flashing is that normal??

is there a way to calibrate the gun
oh and i forgot to mention all the games i got have no keys so eventually i have to drill them and change the locks
so my question is where the dip-switch located in starblade ??
i cant find it on the back
thank you in advance
