Figure 20 on page 25 shows the cartridge storage cell labeling.

Wall number

The wall numbers „3… that are even-numbered represent the walls on the front doors of the library. The wall numbers that are odd-numbered represent the walls on the rear of the library.

Column letters

The column letters „1… range from A to E and are labeled from left to right.

Note: The control unit frame has only four columns; therefore, the letter range is from A to D.

Row numbers

The row numbers „2… range from 1 to 20 or from 1 to 40, depending on the frame and the wall. The numbers start with 1 at the top of the frame and end at 40 for the lowest row.
