Shown here are various versions of the printed paperwork that came with each SL-HF2100. On the left are the correction sheets that were included with each printing. These were necessary so the new owner could make certain corrections to the "Operating Instructions" and the remote "Quick Reference Guide" shown in the center. There were four versions of the instructions and two versions of the guide (that I am aware of). The bulletin sheets on the right were for updating the service manual each time. Click on the picture to see the part numbers on the booklets up close and then click again to see the error that never got corrected. It is setting there in plain sight. ©Misterßetamax go to homepage
