few questions on the hyperion charger

[blueb8llz]

for those of you guys that own a hyperion charger, does the charger automatically read how many cells your trying to charge or do i do it manually? im trying to chage my 7 cells gp 3300 nimh packs and i cant seem to make it charge 7 cells. how do i do it?
also, what amp should i discharge my 7 cell gps at? my charger did not come with any instructions and their website doesnt explain well either.

thanks
