PRE-WIRING OF FUNCTION SELECTOR SWITCH
REFER TO FIGURE 1.
NOTE: Before wiring, be sure the switc.h rotor segmeqts are positioned with respect to the
switch contacts as shown in Figure 1. Also note red mark adjacent to terminal 43. This
will assist you in locating the switch terminals.

6. Connect R5 (27.10, 1% wire-wound precision reSistor) from SF 35 (Don't Solder)
throughSF 30 (Don't Solder) to SF 18 (Don't Solder). Now solder SF 30. (Use extra
care
to
make a good solder joint at SF 30.) Carefully position this resistor away
from contacts, metallic deck spacer, and moving parts of switch.
