For every action involving the EEROM on my 8563E I get the ERR 700 message. So it is impossible for example to save a POWER ON STATE (ERR 101). Actions involving RAM stored data work perfectly. Is it possible to get this EEROM (U500 or 501 on A2 board) for a repair ? Or am I doing something wrong on this instrumet which is otherwise perfectly working ?
