Figure correction in service manuals

November 1, 1994

The block diagram in these manuals is incorrect. This affects the following figures:

502 manual (P/N 170310) Figure 12

402, 802 II manual (P/N 174785) Figure 22

For example, in the original block diagram, for the Channel 1 High Frequency Output, P7-6 (+) is shown connected to pin 3. In reality, it's connected to pin 2. All output connections have been corrected in the new diagram. This agrees with the controller schematics in both manuals.

Additionally, the Channel 2 High and Low Freq. outputs had their connections listed backwards. P11 (Low Freq.) is now P12, and P12 (High Freq.) is now P11.

A corrected block diagram is attached. This replaces both figures mentioned above.
