fiberstars lights dont light up!!!!!

Hello everybody, im trying to figure out and clean up my parents pool and came across our fiber optic lighting and cant seem to get it to work properly. its a fiberstars HID luminaire model 6004 and the problem is that when its on it doesnt light up the whole pool. it just lights up a little bit, but doesnt seem to light up the whole pool if any at all. any suggestions???? or maybe the settings are wrong? please help.
