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

The oven vent
Hot air and moisture escape from the oven through a vent under the right rear surface unit. You can cook on the unit or keep food warm on it while the oven is on. The vent is needed for air circulation. Do not block the vent. Poor baking/ roasting can result. NOTE: Plastic utensils left over the vent can melt.
Burn and Fire Hazard If you leave a utensil on the right rear surface unit, use potholders when moving it. Pan handles can become hot enough to burn. Keep flammable materials away from oven vent. Failure to do so can resuk in burns or a fire.
