Mains Input Selection Selection of mains input range is done at the appliance inlet
(A1FL1) on the back panel. For 115 V ac
±
10%, set the
selector to the 115 V position. For 230 V ac
±
10%, set the
selector to the 230 V position. Either selection will accept 50
or 60 Hz.
To change the voltage selection:
1. Disconnect the appliance coupler.
2. With a flat blade screwdriver, or similar tool, open the
cover.
3. With a flat blade screwdriver, or similar tool, remove the
