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.

7. Mounting of Tonearm
a) To cut blank mounting board i) Use template provided by manufacturer and mark position of cuts. Bear in mind that there must be adequate space to close lid and for counterweight. Also check position of tonearm output cable. ii) Unscrew four screws securing mounting board using Alan key provided (No. 5) iii) Make cuts on board. Note that board is of medite which is easy to cut. iv) Fix tonearm base to board as instructed and replace mounting board, tightening screws with Alan key. With pre-cut board If board is pre-cut it may still be convenient to remove board to attach tonearm base (see ii and iv above) though this is not always necessary. b) Fix tonearm into arm base. c) The weight of the tonearm will have altered the height of the platter from the turntable top.This should be readjusted using the four black knobs to regain the required height between platter and top plate of 2 - 3 mm. Ensure that the height is even around the circumference of the platter (Figs. 6 and 7) NOTE: Anticlockwise lowers platter, clockwise raises. d) Securing tonearm cable You will need a large screwdriver. i) Close lid and detatch power supply. ii) Position turntable so that right rear corner extends well over table edge (back leg should extend over edge). (Fig. 11) iii) There are two fixing points for the cable, one on the subchassis A. and the other on frame near rear leg B. Secure cable in curve between these two points. Ensure that there is adequate cable from tonearm to allow for height adjustment of tonearm. (Fig. 12)
