This product is equipped with an AC power
inlet and must be connected to a three-wire
grounded plug.
The AC power cable must be plugged into an
appropriate outlet that is correctly installed
and grounded in accordance with all local elec-
trical safety codes and ordinances.
If hum or ground-buzz is induced into the
system, remove the rear-mounted
GROUND-LINK. This is ground-link isolates
the AC chassis ground from the audio ground.
When the LINK is removed, the AC ground
remains connected to the chassis via the AC
inlet connector and provides a direct path for
any electrical fault or dangerous condition.
Warning! No ground adaptor should ever be
used with this unit.
3.3 AC Voltage Selection
Before connecting the Vt-737sp to the AC
supply, check the OPERATING VOLTAGE

nected to the AC inlet.
2. Insert a small flat-head screwdriver tip into

the hinged cover from left to right.
3. Rotate the selector wheel to show the
correct voltage for your location, then push the
