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

signal
The dryer sounds a signal to let you know when the cyde is finished. The signal is helpful when you are drying permanent press, synthetics, and other items that should be taken out as soon as the dryer stops. The signal is not adjustable and cannot be turned off.
