Hey. Ive got a unit which after being shut off by a simulated power outage, returns an error code ER11 or as its is displayed "00:11 Er" flashing.

I have two other units which restart, flash the same error code for a couple of seconds then return to normal operation.

Fujitsu tech support wont be open till monday and I want to try and fix it on sunday. Its in a bank refurb so can only be done at night or weekends.

If anyone can help that would be awesome..

Cheers
