FOR YOUR SAFETY
110 V/ 220 V
Units shipped to the U.S.A. and Canada are
designed for operation on 120 V AC only.
Units shipped to countries other than the above
countries are equipped with an AC voltage selector
switch on the rear panel. Refer to the following
paragraph for the proper setting of this switch.
Safety precaution with use of a polarized AC plug.
However, some products may be supplied with a
nonpolarized plug.
AC VOLTAGE SELECTION
This unit operates on 110 - 220 V AC. The AC
voltage selector switch on the rear panel is set to
the voltage that prevails in the area to which the
unit is shipped.
Before connecting the power cord to your AC outlet,
make sure that the setting position of this switch
matches your line voltage. If not, it must be set to
your voltage in accordance with the following
direction.
CAUTION : To prevent electric shock, match wide
blade of plug to wide slot, fully insert.
ATTENTION : Pour eviter les choc electriques,
introduire la lame la plug large de la borne
correspondante de la prise et poussre jusqu’au
fond.
FOR EUROPE AND AUSTRALIA
FOR YOUR SAFETY
230 V/240 V
AC voltage selector switch
Units shipped to Australia are designed for
operation on 240 V AC only.
To ensure safe operation, the three-pin plug
supplied must be inserted only into a standard
three-pin power point which is effectively earthed
through the normal household wiring. Extension
cords used with the equipment must be three-core
and be correctly wired to provide connection to
earth. Improper extension cords are a major cause
of fatalities.
AC 110 V
AC 220 V
Move switch lever to match your line voltage
with a small screwdriver or other pointed tool.
The fact that the equipment operates satisfactorily
does not imply that the power point is earthed and
that the installation is completely safe. For your
safety, if in any doubt about the effective earthing
of the power point, consult a qualified electrician.
PAN-EUROPEAN UNIFIED VOLTAGE
All units are suitable for use on supplies 230 - 240 V
