S.T.A.L.K.E.R. Trainer +6 v-1

[kenshinco]

hi Caliber,
i'm confuse about using your +11 trainer.
in the instruction there are 2 section. one is "press numpad 1..." second is "+ 1..."
so how do i use this +11 trainer?
does this mean on the numpad press both the plus(+) sign and number?
if so what about the +10 and +11? (just press the + and double 1?)
whenever i press the numpad i hear a bip. how do u know if it on or off?
i'm very confuse.
