Um..Im trying to find a manual for my old weather station WR108Z it says on the radio. It quit telling me about storms and wednesday testing all went away when the battery died. I put 3 double a's in it but it never worked unless I push the botton to hear the weather and now its just static. Did I use the wrong kind of battery? I remember the first set was all bunched together battery unit. Im lost..can ya tell? S.O.S
