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

Operating Your Air Conditioner
To obtain the best possible results from your air conditioner, it is important that you operate it properly. This section tells you how to set the controls and how to direct the cooled air.
Starting
your
air conditioner
Fire Hazard Do not use an extension cord. Doing so can result in death, fire, or electrical shock.
Electrical Shock Hazard Plug into a grounded 3-prong outlet. Do not remove ground prong. Failure to follow these instructions can result in death or electrical shock.
1. Set the System Control to the
desired setting. LO COOL - for sleeping comfort Hi COOL - for maximum cooling FAN ONLY -to circulate room air without cooling it 2. Turn the Thermostat Control to number 6 (mid setting). You can adjust the air conditioner�s cooling performance by setting the Thermostat Control to a higher number for more cooling or to a lower number for less cooling. Experiment to find the setting(s) that suits you best.
IMPORTANT: If you turn the air conditioner off, or if the compressor turns off when you lower the Thermostat Control, wait at least three minutes before turning the air conditioner back on. If you don�t wait, you may blow a fuse or trip a circuit breaker.
