The AM700 is shipped from the factory set for the operating voltage of the
destination country (115 VAC or 230 VAC). If the setting is not correct, it must be
changed before connecting the power cord to the power source.
1. Turn off the rear-panel power switch and disconnect the power cord from the
mains supply (see Figure 1-1).
2. Set the voltage range selection switch (located on the rear panel of the AM700)
to the correct position for operation.
Instruments are shipped with the power cord most appropriate for the country of
destination. Available power-cord option information is given in Table 1-1. Contact
your Tektronix representative or local Tektronix field office for additional
power-cord information.
CAUTION. When changing the line voltage selector switch you must also change
the fuse to provide proper protection for the operating voltage in use.
