After not being used for some time, my Multiplex mc 4000 profi gives the message:multiplex p 4000 and version 2.0. display keeps flashing.What could be the problem and can I solve it myself?Battery and backup battery are ok
Dear Bootje,
its time to send it to Multiplex, maybe it is a fault with the RAM or the Backup battery is empty, or the Mainswitchboard has a problem, however there is no easy solution to fix it.
