Hi, was it working before you needed to change the batteries, have you put them in the right way round and did you check their was no seal on one side of the batteries.
let me know what you have done and if it was working before.
i cant remember if the batteries go in facing the same way or if one goes in the other way round, let me know what you have done then ill have a look around to check which way the batteries go in.
if you have bought cheap batteries then this could be your problem as ll the cheap ones are good for is cheap watches so bare this in mind.
