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

Dryers require regular maintenance. Follow the suggestions below to maintain your dryer properly.
Maintenance-every
Cleaning the lint screen
load I
Product and Fabric Damage Hazard Do not run the dryer with the lint screen loose, damaged, blocked or missing. Doing so can cause overheating and damage to both the dryer and fabrics.
The lint screen is located under a lid on top of the dryer. Clean lt before each load. A screen blocked by lint can increase drying time.
1. Open the lid and pull the lint screen straight out.
2. Roll lint off the screen with your fingers. Do not rinse or wash the screen to remove lint. Wet lint is hard to remove. 3. Push the lint screen firmly back into place and close the lid.
Lint
signal
(on some models)
Restricted airflow reduces drying efficiency. The signal (a whistle tone) lets you know if the airflow is restricted. l Turn off the dryer and clean the lint screen. NOTE: Clean your lint screen before each load. Do not wait for the lint signal. The lint signal indicates excessive lint present on your lint screen. If you wait for the lint signal before you clean the lint screen, drying efficiency will be reduced.
