for 208Vac Operation (Model 6259B, 6260B, 6261B,
6268B, and 6269B) and 115Vac Operation
(Except Model 6269B)
b. Unsolder wire from circuit breaker A5CB1
connected to "230V" terminal of bias transformer
A3T2 and solder it instead to "208V" terminal of
transformer (see Figure 2-2 B). Leave wire from fan
B2 (not used in 62599) soldered to "230V" terminal.
c. Re-install RFI assembly by reversing pro-
cedure of Step (a).
