IMPORTANT SAFEGUARDS
19. DAMAGE REQUIRING SERVICE
Unplug this unit from the wall outlet and refer servicing to qualified service personnel under the following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the unit.
c. If the unit has been exposed to rain or water.
d. If the unit does not operate normally by following the operating instructions. Adjust only those controls that are covered by
the operating instructions, as an improper adjustment of other controls may result in damage and will often require extensive
work by a qualified technician to restore the unit to its normal operation.
e. If the unit has been dropped or the cabinet has been damaged.
f. When the unit exhibits a distinct change in performance, this indicates a need for service.
20. REPLACEMENT PARTS
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 parts.
Unauthorized substitutions may result in fire, electric shock or other hazards.
21. SAFETY CHECK
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.
22. WALL OR CEILING MOUNTING
The product should be mounted to a wall or ceiling only as recommended by the manufacturer.
23. HEAT
The product should be situated away from heat sources such as radiators, heat registers, stoves, or other products (including
amplifiers) that produce heat.
24. DISC TRAY
Keep your fingers well clear of the disc tray as it is closing. It may cause serious personal injury.
25. CONNECTING
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.
26. SOUND VOLUME
Reduce the volume to the minimum level before you turn on the product. Otherwise, sudden high volume sound may cause
hearing or speaker damage.
27. SOUND DISTORTION
Do not allow the product output distorted sound for a longtime. It may cause speaker overheating and fire.

When you use the headphones, keep the volume at a moderate level. If you use the headphones continuously with high volume
sound, it may cause hearing damage.
29. LASER BEAM
Do not look into the opening of the disc tray or ventilation opening of the product to see the source of the laser beam. It may cause sight damage.
30. DISC
