FOR VOUR SAFETV

To ensure safe operation the three-pin plug supplied must be inserted only into a standard three-pin
power point which is elfectivly aarthad through the normal husahold wiring.
Extension cords used with the equipment must be three-con and be correctly wired to provide
connection to earth. Wrongly wirad extension cards are a maior cause of Iatalities,
The iact that the equipment operates satisfactorily does not imply that the power point is earthed and
that the installation is completely safe. For your safety, ii in any doubt about the ellective earthing of the
power point, consult a qualified electrician.

For U.S.A. and Canada models.

CAUTION

TO PREVENT ELECTRIC SHOCK DO NOT USE THIS (POLARIZED) PLUG WITH AN EXTENSION '
CORD, RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSEFITED TO
PREVENT BLADE EXPOSURE.
