Hi Debrah, This is exactly the symptom you get when the battery fails. The CS-700 has an internal rechargeable battery that may have failed. It should be tested and replaced before programming. The machine will use the battery to support the memory when the power is turned off. Sometimes the charge circuit can be the cause and the battery will just discharge, but never re-charge again, but this is rare. I would still guess that the battery has not been replaced, or not correctly. It is usually soldered to the main circuit board and should be replaced by a professional and then the RAM clear procedure should be carried out to prepare memory for programming.
