POWER SOURCE

This product is designed to operate on normal 120V 60Hz AC only. Attempting to operate this system from any other power source may cause damage to the system, and such damage is not covered by your warranty.

NOTE: You will note that this system is equipped with a polarized AC power plug having one blade wider than the other. This is a safety feature. If this plug does not fit into your existing AC outlet, do not

try to defeat this safety feature by filing the wide blade to make it fit into your outlet. If this plug will not fit into your outlet, you probably have an out-

dated non-polarized AC outlet. You should have your outlet changed by

a qualified licensed electrician.

PROTECT YOUR FURNITURE

This model is equipped with non-skid rubber 'feet' to prevent the product from moving when you operate the controls. These 'feet' are made from non-migrating rubber material specially formulated to avoid leaving any marks or stains on your furniture. However certain types of oil based furniture polishes, wood preservatives, or cleaning sprays may cause the rubber 'feet' to soften, and leave marks or a rubber residue on the furniture. To prevent any damage to your furniture we strongly recommend that you purchase small self-adhesive felt pads, available at hardware stores and home improvement centers everywhere, and apply these pads to the bottom of the rubber 'feet' before you place the product on fine wooden furniture.

IMPORTANT: Raising And Lowering The Lid

To open the lid, raise it as far as it will go until the lid support bracket ‘locks’in the open position.

To close the lid, lift it upward slightly until the lid support bracket ‘unlocks’, and then gently lower the lid.

TO AVOID DAMAGING THE CABINET OR THE LID, NEVER FORCE THE LID CLOSED. ALWAYS RAISE THE LID TO RELEASE THE LID SUPPORT BRACKET.
