CHANGING UPPER BOARD SWITCH SETTINGS
Two banks of switches are used each with 8 positions. Both are mounted on
the upper (smaller) circuit board and are easily identified as rectangular red
blocks with 8 white switches. The switch block nearest to the cable entry and
fuses is switch block 2, the other of course being switch block 1. On each
switch block the individual switches are number 1 to 8.
One side of the switch block is marked OPEN, when this side of the white
rocker is down the switch is open, when it is up the switch is closed. It may
be necessary to use open or similar pointed instrument to operate the rocker.
