There are three types of an AC power noise filter: 60Hz, 50Hz and OFF. When set to OFF,
the filter will not be applied. If the filter is set to 50Hz or 60Hz, then the AC filter will
remove 50Hz or 60Hz power noise correspondingly. In the U.S., the AC filter should be
set to 60Hz. Check the properties of your power source before setting AC filter
properties.
Under battery power, there would be no AC noise being generated. In this case,
please set the AC filter setting to OFF so that output signal would not be distorted.
The status of the AC filter can be checked on the bottom part of the printout -
indicating AC 60Hz, AC 50Hz or AC OFF
