The Ringnode's hardware switches

Some text is printed on the reverse of the board to indicate the function of each of the eight switches in switch block 2. Each individual switch is identified by a pair of numbers. The first number indicates the switch block, and the second number identifies the particular switch within the switch block. For example, switch 2/1 means block 2, switch 1.
