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.

MAINTENANCE AND CLEANING
Before any maintenance or cleaning is carried out you must DISCONNECT the appliance from the electricity supply.
The dangers of freezing
If the machine is exposed to temperatures below 0°C, certain precautions should be taken.
n
Descaling
The water we normally use contains lime. It is a good idea to periodically use a water softening powder in the machine. Do this separately from any laundry washing, and according to the softening powder manufacturer's instructions. This will help to prevent the formation of lime deposits.

Turn off the water taps. Select a wash programme and run for a few seconds. Unscrew the inlet hoses. Unhook the drain hose from the rear support and position the end in a bowl. Run the draining programme for a few seconds. When you intend to start the machine up again, make sure that the room temperature is above 0°C.
n
After each wash
Leave the door open for a while. This helps to prevent mould and stagnant smells forming inside the appliance. Keeping the door open after a wash will also help to preserve the door seal.
External cleaning
Clean the exterior cabinet of the appliance with soap and water only, and then dry thoroughly.
Cleaning the dispenser drawer
From time to time the washing powder and additive dispenser drawer should be cleaned. Remove the drawer by pressing the catch downwards and by pulling it out. Flush it out under a tap, to remove any traces of accumulated powder.

Cleaning the drawer recess
Having removed the drawer, use a small brush to clean the recess, ensuring that all washing powder residue is removed from the upper and lower part of the recess. Replace the drawer and run the rinse programme for a few minutes without any clothes in the drum.
