"Cleaning Electric Movements" dated April 20, 2009. Scroll back down to that post and you'll see a lot of general information about cleaning a Timex Electric movement. Of course, the movement that the post pertains to is a Timex #40 movement but I doubt that the issues concerning the Dynabeat are much different from those of the standard electric/mechanical.
I'm certain someone here on the Forum has much more detailed information on the Dynabeat than I have. Sorry I can't be of more help. By the way, don't forget to put your name on your next post so we can call you by name.
