When replacement parts are required, be sure the service technician uses replacement parts specified by
the manufacturer or those that have the same characteristics as the original part.
Unauthorized substitutions
may result in fire, electric shock or other hazards.
Upon completion of any service or repairs to this unit, ask the service technician to perform safety checks to
determine that the unit is in proper operating condition.
When you connect the product to other equipment, turn off the power and unplug all of the equipment
from
the wall outlet. Failure to do so may cause an electric shock and serious personal injury. Read the owner's
manual of the other equipment carefully and follow the instructions when making any connections.
Reduce the volume to the minimum level before you turn on the product. Otherwise, sudden high volume
sound may cause hearing or speaker damage.
Do not allow the product to output distorted sound for an extended period of time. It may cause speaker
overheating and fire.
This reminder is provided to call the cable TV system installer's attention to Article 820-40 of the NEC
that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be
connected to the grounding system of the building, as close to the point of cable entry as practical.
