Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Thank you for your manual It has the basic things to and i use the Oszi for Longer Time.

Description of the appliance
� The hood is supplied as an extractor unit and can also be used with a filtering function by fitting one charcoal filter. � You will need an original ELECTROLUX charcoal filter for this function (Available from your local ELECTROLUX Service Force Centre). Attention! Certain models are already equipped with charcoal filters. The charcoal filters are attached to one side of the polystyrene protection panels in the packaging and should be fitted into place prior to using the cooker hood in the recirculation version.
