Replacing the memory unit

When you replace the BCU-12 control unit, you can move the memory unit to the new 

control unit to keep the firmware and parameter settings.

WARNING!

 Do not remove or insert the memory unit when the control unit is 

powered.

To remove the memory unit, open the fastening screws [1] and pull the memory unit [2] 

out.
