IMPORTANT SAFEGUARDS
(CONTINUED)
OUTDOOR ANTENNA GROUNDING
If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is grounded
so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National
Electrical Code, ANSI/NFPA 70, provides information with respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of
antenna discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.
SERVICING
Do not attempt to service this unit yourself as opening or removing covers may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service personnel.
DAMAGE REQUIRING SERVICE
Unplug this unit from the wall outlet and refer servicing to qualified service personnel under the following
conditions:
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.
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.
WALL OR CEILING MOUNTING
The product should be mounted to a wall or ceiling only as recommended by the manufacturer.
HEAT
The product should be situated away from heat sources such as radiators, heat registers, stoves, or other
products (including amplifiers) that produce heat.
DISC TRAY
Keep your fingers well clear of the disc tray as it is closing. It may cause serious personal injury.
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.
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.
SOUND DISTORTION
Do not allow the product output distorted sound for a longtime. It may cause speaker overheating and fire.
HEADPHONES
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.
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.
DISC
Do not use a cracked, deformed, or repaired disc. These discs are easily broken and may cause serious
personal injury and product malfunction.
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV 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.
