3.3 RAM-initialisation

In rare cases, it is possible that major interference signals such as line spikes and light-

ning can have an adverse influence on the contents of the data memory. If the contents

of the data memory are undefined, this is indicated after “power on“ with ‘error 5'. The

keyboard is then blocked, no entering is possible until the RAM is initialised again.

Disconnect all cables at rear, except mains cable.

Power off and wait 5 s.

Power on and simultaneously press key <FILL> and keep pressed until

RAM init.
