The FM500 operates on 100, 120, 220, or 240 volts AC (50 or 60 Hz; single phase).
As shipped (factory default settings), the FM500 operates on 120 volts at 60 Hz.
If you are operating the transmitter at 120 volts you do not need to make any
changes. To operate the FM500 at 100, 220, or 240 volts, a few changes are
necessary.
To change the voltage setting, follow these steps:
1. Disconnect the power cord if it is attached.
2. To set the input voltage for 100 volts, skip to step 7.
3. Open the cover of the power connector assembly using a small, flat blade
screwdriver. See Illustration 2–2.
4. Insert the screwdriver into the top slot of the voltage selection assembly
(red) and pry out the assembly from the power connector.
5. If you are setting the input voltage for 220 or 240 volts, replace the installed
fuses with 12 amp fuses (included in your package). See Illustration 2–3.
6. Replace the red fuse assembly so that the "230V" setting appears right side up
in the window. Close the assembly window.
