I bought this clock at an estate sale and it runs. But, when the clock says 5:30 it will strike 5 times and 1 time on the hour... (This is just an example).

Is there something I can do to make it strike, 5 times at 5:00 and 1 time at 5:30? I uploaded a picture, but I'm not sure if you can see it.( I can't). So let me know..
