external objects do not fall into and liquids are not spilled onto
any openings or vents located on the product.

supply only of the type described in the operating instructions
or as marked on the unit. If you are not sure please consult the
dealer or local power company.

such as radiators, heat registers, stoves or other appliances
(including amplifiers) that produce heat.

7. SERVICING - The user should not attempt to service the

unit beyond those methods described in the user’s manual.
Opening or removing covers will expose you to dangerous
voltage and other hazards. Service methods not covered in the
user’s manual should be referred to qualified service personnel.
