Hi, these run on 4 AA batteries. There is a battery compartment in the back. Any chance you could test? Also could you tell me if there are any cartridges loaded in the bottom? (there are three slots) Thanks acsi (849 ) 10:34 pm, Tue 19 Mar
Sorry don't know much about this but will try to answer.There are no cartridges in the slot.Have put batteries in and something is running.Unfortunately the battery cover is missing -hope that isn't too much of a pain.Thanks
Hmm I sort of hate to think whats running as these normally don't make any noise. Since I placed the question I see that the two heavy weights are in anyway so I guess I'm out.
