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 you for your manual It has the basic things to and i use the Oszi for Longer Time.

Operation
Reprogramming the timers
The grease filter timer is preset to 30 hours. This time can be lengthened or shortened to 20, 30, 40, or 50 hours. � A time of 20 hours should be programmed in kitchens with frequent pan or deep frying. � A time of 20 hours should also be programmed if the kitchen is only used occasionally to prevent grease which has accumulated over a long period of time from hardening on the filters making cleaning more difficult. Reprogramming the grease filter timer ^ Store the selection by pressing the grease filter button. If the procedure is not stored within 4 minutes of programming, the hood will automatically default to the "old" data.
The lit indicator shows the programmed time: 1st indicator from the left 2nd indicator from the left 3rd indicator from the left 4th indicator from the left = = = = 20 hours 30 hours 40 hours 50 hours
^ Use the "�/+" button to select the desired time.
^ Press the On/Off button to turn off the fan.
^ Press the Delayed Shut Down and grease filter buttons at the same time. The indicator for the grease filter and one of the "�/+" indicators will flash.
