It is probably the capacitor4s which are charged which keeps the meory alive when the battery is removed. As previously mentioned a jumper point can be shorted out to fully discharge the capacitors. Alternatively if you are confident enough the two contacts that connect to the battery can also be shorted out usind a small bit of wire or a terminal screwdriver.<br />But only attempt this if you are confident and are sure of what you are doing and never with the power supply on, and and remember to watch out for staic build up , use anti static strap or earth your self to something.
Good luck and let us know how you do
