FREQUENCY CONTROL SWITCH.--This
switch is located next to the governor mode
switch/indicator and is labeled FREQ. It is a
three-position switch, spring loaded to center
position. The center position is labeled OFF,
which is the normal position of the switch. When
the switch is turned to the right or the RAISE
position, it will cause the frequency of the
generator to increase. When the switch is turned
to the left or the LOWER position, it will cause
the frequency of the generator to decrease.
