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´s for your help, I already recived these manual from you

If the plug that is fitted to your appliance is not suitable for your socket outlet, it must be cut off and the appropriate plug fitted. Remove the fuse from the cut off plug. The cut off plug should then be disposed of to prevent the hazard of shocks in case it should be plugged into a 13amp socket in another part of your home. Important The wires in the mains lead are coloured in accordance with the following code: Green and Yellow Blue Brown - Earth - Neutral - Live This appliance complies with the E.E.C. Directive No. 87/308 of 2.6.87 relative to radio interference suppression. This appliance complies with the following E.E.C. Directive: - 73/23 EEC of 19.2.73 (Low Voltage Directive) and subsequent amendments. - 89/336 EEC of 3.5.89 (Electromagnetic - Compatibility Directive) and subsequent amendments. Please ensure that when the appliance is installed it is easily accessible for the engineer in the event of breakdown.
If you fit your own plug, the colours of the wires in the mains lead of your appliance, may not correspond with the markings identifying the terminals in your plug, proceed as follows: Connect the Green and the Yellow (earth) wire to the terminal in the plug which is marked with the letter «E» or the earth symbol , or coloured green and yellow. Connect the blue (neutral) wire to the terminal in the plug which is marked with the letter «N» or coloured black.

For replacement, use a 13amp BS1362 fuse. Only ASTA or BSI approved fuses should be used. The plug must not be used if the fuse cover/carrier is lost. The cover/carrier is indicated by the coloured insert at the base of the plug. A replacement cover/carrier must be obtained from your local Service Force Centre.
