If caller IDs cannot be displayed because reverse polarities cannot be detected due to a
large difference between line voltages in a reverse polarity condition and in a steady
condition, increase the judgment voltage.
However, do make sure that the voltage value set by selectors 1 through 3 of this switch is
equal to, or greater than, the value set by selectors 4 through 6 of the same switch.
