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.

â¢ Recirculation fitting â¢ The filtered air is returned to the room through the two plastic venting grilles G located on the lower chimney stack I. â¢ Connect additional recirculation spigot P to the round diffuser outlet, pushing it downwards, and fit spigot R to additional spigot P in a similar manner (ensure that the two additional recirculation spigots P1 are fitted to spigot R). Cut additional recirculation spigot P at a point corresponding to outlets 1 and 2, indicated directly on the additional spigot. Make sure that the height of the assembly R + P corresponds to the height of the chimney outlet. â¢ Fit the activated charcoal filters inside the hood canopy (see paragraph on Maintenance).Do not fit the venting grilles; this must only be done after installation of the chimney stack.
Connection to the mains power supply
â¢ Check that the mains voltage corresponds to the one indicated on the rating plate inside the hood. â¢ Connect the hood to the mains, inserting a two-pole switch with contact aperture of at least 3 mm. â¢ Ensure that the domestic electric system is properly earthed. â¢ The mains lead should be routed through the central keyhole in the frame before being connected. â¢ Connect the mains lead to the power supply.
Fitting the telescopic chimney
â¢ Fit the upper chimney stack S to the frame fastened to the ceiling or to the wooden buttress. â¢ Fasten the upper chimney stack using two of the screws size 2.9x9.5 provided in bag (2), making sure that you insert one screw on each side of the chimney. â¢ Fit the lower chimney stack I in a similar way, using two of the screws size 2.9x9.5 provided in bag (2), inserting the chimney stack into the same slot used for upper chimney stack S. â¢ Fit the two venting grilles, which snap onto the metal, into the housings provided, so that the symbol points upwards and the symbol points forwards. For recirculation versions, also check that the venting grilles are properly inserted into clamp R (fig. 4).
