REFER ALL SERVICING TO A QUALIFIED TECHNICIAN.

The lightning flash with an arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of “DANGEROUS” voltage within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. Users should exercise extra caution when this symbol appears in this instruction manual and follow all precautions as stated.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in this manual.

Clean only with a dry cloth.
Do not store or operate this product near any heat sources such as radiators, heat registers, stoves, or other apparatuses (including amplifiers) that produce heat.

Do not defeat the safety purpose of the polarized or grounding-type plug.
A polarized plug has two blades one wider than the other. A grounding plug has two blades and a round grounding prong. The wide blade or third prong is provided for your safety. If the provided plug does not fit your outlet, consult an electrician for the replacement of the obsolete outlet.
