FT-767GX POWER TRANSFORMER VOLTAGE SELECTION
1f your local AC mains voltage does not match the label on the rear of the FT-767GX, the taps on the
primary winding of the power transformer in the FT-787GX should be changed according to the following
procedure. Make sure to change the label on the rear of the transceiver to match the new voltage after
changing the taps.
1) Disconnect all cables from the transceiver. 8) Locate the white molex connectors (for power
and loudspeaker) inside the rear of the chas-
