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.

BATTERY BALANCE
12: Volume control - Used to set the level of the signal in connected earbuds. 13: Battery LED - This LED lights red when battery level is low and the battery needs to be replaced. 14: Balance control - Adjusts the relative levels of the two signals arriving at the EarAmp stereo input (see #2 on page 4). When set at the center 12 o�clock position, both signals are presented to connected earbuds at equal strength. When the EarAmp� is operating in �Stereo� mode (that is, when the 2 CH/Stereo switch [see #6 on page 5] is set to �Stereo,�) turning the balance control clockwise increases the relative amount of right channel signal (that is, the signal in your right ear) and turning it counterclockwise increases the relative amount of left channel signal (that is, the signal in your left ear). When the EarAmp� is operating in �2 CH� mode (that is, when the 2 CH/Stereo switch [see #6 on page 5] is set to �2 CH,�) both channels are internally mixed to mono and routed to both earbuds. In 2 CH mode, turning the balance control clockwise increases the relative amount of right channel signal (though it will be heard in both ears) and turning it counterclockwise increases the relative amount of left channel signal (again, heard in both ears). 15: Belt clip - Use this to clip the EarAmp� to your belt for convenient operation.
