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.
ThankΒ΄s for your help, I already recived these manual from you

Step 1: Charging your Sony CLIÃ Handheld
Charging with the cradle
Note Before you use your CLIÃ handheld for the first time, make sure to charge it.
Connect the supplied cradle to an AC power source in advance. Charging will start as soon as you place your CLIÃ handheld on the cradle. The battery icon in the screen changes to the battery charging icon ( ). It takes about 4 hours for your CLIÃ handheld to be fully charged for the first time. Subsequent charges, if it is charged frequently, will require less time.
Insert your CLIÃ handheld at an angle to the cradle and lay it back to fit into place.
To the wall outlet
When you place your CLIÃ handheld on the cradle, the cradle indicator turns on and charging starts.
When charging is completed
When you remove your CLIÃ handheld from the cradle, the battery charging icon changes to the battery icon ( ). The cradle indicator remains on even after charging is complete.
Notes â¢ If the battery in your CLIÃ handheld is fully discharged, all data stored on the DRAM (memory) is lost. Performing another HotSync operation once the battery is recharged can restore information saved from the last HotSync operation. â¢ Do not connect the headphones jack on your CLIÃ handheld with the LINE input connector while your CLIÃ handheld is being charged.
