Check your wiring against the wiring diagram in Figure 1. ( ) The unit should now be wired. Install the 4 threaded spacer on the P.C. Board. Use screws and lock washers. do not tighten all the way. (Do not ground spacers to the board) ( ) Install the board to the base of the case. Align the board so that the 2 potentiometers mounted on the bottom of the board may be adjusted thru the holes in the bottom. Attach the board to the case with 4 screws and washers. ( ) Install the shorting block, through the mic power jumper hole, onto one of the two pins. -8-

10 ( ) Plug the ribbon cable into J1. Make sure the Dip cable is plugged such that Pin 1 of the cable plug goes into pin one of the DIP socket on the board. Do not plug any Integrated circuit chips in at this time. ( ) Plug the power transformer into the wall and the Male Din connector from the transformer into the Pwr input of the unit. Turn power on. The Yellow LED above the power on switch should go on. Turn the power off before installing the integrated circuits chips ( ) Plug Integrated circuit chip 74LS123 into U3. ( ) Plug Integrated circuit chip 74HC00 into U2. ( ) Plug integrated circuit chip TL074CN or JRC2060D into U1. ( ) Plug integrated circuit chip 74HC4053 into socket U4. ( ) YOUR UNIT SHOULD BE READY TO TEST. CHECK FIGURE 1 AGAIN TO ASSURE IT IS WIRED CORRECTLY. ( ) Attach the bottom to the top of the case using the 4 screws supplied with the unit ( ) Attach the feet and Serial Number label to the bottom of the case. ( ) Read your OPERATING MANUAL (getting started tutorial) page 14 and 15 to setup the unit. -9-
