Power
• Set the voltage selector switch
before you connect and operate
the unit.
The HD-1 accepts AC voltages
from 90 to 260 VAC, at 50 or 60 Hz,
in four ranges. Select the range that
is closest to the local mains AC
voltage.
Do not switch among AC voltage
ranges with the power cable
connected to an outlet.
Fuse
The HD-1 is protected by a fast-
acting fuse in the voltage selector
switch.
• If the fuse blows, check the line
voltage and the voltage selector
setting.
• Always replace the fuse
with a component of
the same type and
rating.
Power Cable
• Connect the HD-1 to a
three-prong outlet.
If the power cable appears frayed
or broken, replace it immediately
before operating the unit.
