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.

The hood may be used as follows: - Exhausting version - Recycling version Fig. 1
The air is vented outdoors by a 150 mm duct which must be connected to connecting ring with no return valve on top of the motor package. The hood cannot be connected to flues of other appliances that run on energy sources other than electricity. Please, keep to the provisions of official directives regarding the question of fumes discharge.
The air is filtered through a carbon filter and recirculated into the room through the top sides of the chimney (Fig. 2). This version is used when there is no exhaust duct for venting outdoors or when it is impossible to install one.
