Ground Terminal
Connecting the supplemental ground terminal and the line cord safety ground to different
ground potentials creates a ground loop that can damage the Recorder. To avoid this, use the
supplemental ground terminal only when no protective earth ground connection exists through
the line power cord. If there is any chance that a safety ground connection does exist through
the line power cord connection, make sure to connect the supplemental ground terminal only to
the ground system used by the ac receptacle that powers the Recorder. See Figure 3.
