10.
or otherwise; this may result in objects touching dangerous voltage points or shor t-out parts that could result in a personal or property damage or injur y, including re or electric shock. Never spill liquid of any kind on the product.
Ventilation: Any electrically powered consumer electronic product generates heat while in
11.
use, thereby requiring proper ventilation. To ensure reliable operation of the product and to protect it from overheating, do not operate the product on a bed, sofa, rug, or other similar soft sur face, and never block any ventilation slots or openings provided for the unit.

IMPORTANT SAFETY INSTRUCTIONS
Grounding or Polarization: This product may be equipped with a polarized alternating-
14.
current line plug that has one blade wider than the other. This plug will only t into the power outlet in one direction. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the direction of the plug. If the plug should still fail to t, your outlet may be obsolete; contact a licensed electrician to replace it. Never attempt to defeat the safety purpose of the polarized plug.
Power-Cord Protection: Care must be taken to ensure that power supply cords are routed
15.
so as to avoid being damaged, such as by being walked on or pinched by items placed upon or against them. You should pay particular attention to cords at plugs, convenience recep­tacles, and at the point where they exit from the product.
Protective Attachment Plug: The product may be equipped with an attachment plug with
16.
overload protection. This is a safety feature. See the operating instructions for replacement or directions to reset the protective device. If replacement of the plug is required, please consult an authorized service technician, and make sure s/he has used a replacement plug that has the same overload protection as the original plug as specied by the manufacturer.
Outdoor Antenna Grounding: If an outside antenna is connected to the product, be sure
17.
the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Ar ticle 810 of the National Electrical Code, ANS/NFPA 70 provides information with regard 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 (see gure).
Lightning: Lightning can cause power surges, which may damage or destroy your product.
18.
For added protection, unplug it from the wall outlet and disconnect the antenna or cable sys­tem during a lightning storm or when it is left unattended and unused for long periods of time.
Power Lines: An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits, as contact with them might be fatal.

IMPORTANT SAFETY INSTRUCTIONS
Overloading: Always operate any electrical device in accordance with applicable electrical
19.
codes. Never overload wall outlets, extension cords, or integral convenience receptacles as this can result in a risk of personal or property damage or injury, including re or electric shock.
Servicing: Do not attempt to service this product yourself as opening or removing covers
20.
may expose you to dangerous voltage or other hazards, including the risk of injury or dam­age to persons or property. Your warranty will also be voided. Refer all servicing to qualied
service personnel.
Damage Requiring Service: Unplug this product from the wall outlet and refer servicing to
21.
qualied service personnel if: a) the power-supply or plug is damaged in any way; b) liquid has been spilled or if objects have fallen or been introduced into the product; c) the product has been exposed to rain, water or other sources of moisture; d) the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions as improper adjustment of other controls may result in damage and/or require extensive work by a qualied service technician to restore the product to its normal operation; e) the product has been dropped or damaged in any way; f) the product
exhibits a distinct change in performance indicative of a need for ser vice.
Replacement Parts: When replacement parts are required, be sure that your service techni-
22.
cian has used replacement par ts specied by the manufacturer or have the same charac­teristics as the original par t. Unauthorized substitutions may result in injury to property or persons including the risk of re, electric shock, or other hazards, and your warranty will be
voided.
Safety Check: Upon completion of any service or repairs to this product, ask the service
23.
technician to perform appropriate safety checks to ensure that the product is in proper op­erating condition.
Wall or Ceiling Mounting: the product should only be mounted to a wall or ceiling only as
24.

CONTROLS AT A GLANCE
The remote control transmits a directional infrared beam. Be sure to aim the
remote control directly at the infrared remote sensor during operation. The sen­sor may not be able to receive signals properly if the sensor is covered, if there is a large object between the remote control and the sensor, or if it is exposed to direct sunlight or a strong articial light (e.g., uorescent or strobe lights). In this case, change the direction of the light or reposition the unit to avoid direct
lighting.
To use the remote, point it at the remote sensor of the player. Operate the
remote within 15 feet of the sensor and at an angle of ± 60 degrees.
To install batteries in the remote
control, refer to the diagram. Re­move the battery compartment
cover located on the rear of the
remote control. Insert batteries, making sure to match their polari­ties (+/-) to the markings on the in-
side of the compartment. Replace the cover.
Batteries in the remote will last for
approximately 1 year. Replace the
batteries if the remote control does
not work. Do not mix old with new batteries, or different types of bat-
teries.
Remove the batteries from the re-
• mote if it will not be used for a long period of time.
Thebatteriesusedintheremotecontrolmaypresentareorchemical
burn if mistreated. Do not recharge, disassemble, incinerate, or heat the battery (~212ºF).
Keep batteries away from children.
