IMPORTANT SAFETY INSTRUCTIONS
Your Unit is designed and manufactured to operate within defined design limits, and misuse may result in electric shock or fire. To prevent your Unit from being damaged, the following rules should be observed for its installation, use, and maintenance. Please read the following safety instructions before operating your Unit. Keep these instructions in a safe place for future reference.
- Read these instructions.
- Keep these instructions.
- Heed all warnings.
- Follow all instructions.
- Do not use this apparatus near water.
- Clean only with a dry cloth.
- Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
- Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
- Only use attachments/accessories specified by the manufacturer.
- Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
- Unplug this apparatus during lightning storms or when unused for long periods of time.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as when the power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
- To reduce the risk of electric shock or component damage, switch off the power before connecting other components to your Unit.
- Unplug the power cord before cleaning your Unit. A damp cloth is sufficient for cleaning. Do not use a liquid or a spray cleaner on your Unit. Do not use abrasive cleaners.
- Always use the accessories recommended by the manufacturer to insure compatibility.
- When moving your Unit from an area of low temperature to an area of high temperature, condensation may form in the housing. Wait before turning on your Unit to avoid causing fire, electric shock, or component damage.
- Slots and openings in the back and bottom of the cabinet are provided for ventilation. To ensure reliable operation of your Unit and to protect it from overheating, be sure these openings are not blocked or covered. Do not place your Unit in a bookcase or cabinet unless proper ventilation is provided.
- Never push any object into the slots and openings on your Unit enclosure. Do not place any objects on the top of your Unit. Doing so could short circuit parts causing a fire or electric shock.
Never spill liquids on your Unit.
- The power cord must be replaced when using different voltage than the voltage specified. For more information, contact your dealer.
- When connected to a power outlet, power is always flowing into your Unit. To totally disconnect power, unplug the power cord.
- The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of un-isolated, dangerous voltage within your Unit that may be of sufficient magnitude to constitute a risk of electric shock to persons.
- The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and servicing instructions in the literature accompanying your Unit.
- Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
- The wall socket should be located near your Unit and be easily accessible
- Keep your Unit away from moisture. Do not expose your Unit to rain or moisture. If water penetrates into your Unit, unplug the power cord and contact your dealer. Continuous use in this case may result in fire or electric shock.
- Do not use your Unit if any abnormality occurs. If any smoke or odor becomes apparent, unplug the power cord and contact your dealer immediately. Do not try to repair your Unit yourself.
- Avoid using dropped or damaged appliances. If your Unit is dropped and the housing is damaged, the internal components may function abnormally. Unplug the power cord immediately and contact your dealer for repair. Continued use of your Unit may cause fire or electric shock.
- Do not install your Unit in an area with heavy dust or high humidity. Operating your Unit in environments with heavy dust or high humidity may cause fire or electric shock.
- Ensure that the power cord and any other cables are unplugged before moving your Unit.
- When unplugging your Unit, hold the power plug, not the cord. Pulling on the power cord may damage the wires inside the cord and cause fire or electric shock. When your Unit will not be used for an extended period of time, unplug the power cord.
e • To reduce risk of electric shock, do not touch the connector with wet hands.
- Insert the remote control battery in accordance with instructions. Incorrect polarity may cause the battery to leak which can damage the remote control or injure the operator.
• See the important note and rating located on the bottom of the unit.
- WARNING - This equipment is not waterproof. To prevent a fire or shock hazard, do not place any container filled with liquid near the equipment (such as a vase or flower pot) or expose it to dripping, splashing, rain, or moisture.

INFORMATION ON HEARING DAMAGE
Understanding Noise Induced Hearing Loss
Exposure to loud sounds can damage your hearing, causing hearing loss and tinnitus (ringing or buzzing in the ears). While a variety of things can lead to hearing loss, including aging and side effects of certain medications, the most common cause of non-age-related hearing damage is loud noise. Extremely loud sounds, such as gun shots or firecrackers at close range, can cause immediate hearing damage. Hearing damage can also occur over time due to repeated exposure to loud sounds such as industrial noise or loud music. With continued exposure to loud noises, ears may become accustomed to the sound level, which may result in permanent damage to hearing without any noticeable discomfort.
Temporary and Permanent Hearing Loss
Noise induced hearing loss and tinnitus may be temporary or permanent. Ears typically recover from temporary hearing damage in a short time. However, ears may not recover completely, and some damage may be permanent. Repeated exposure to loud sound can cause more and more damage, and eventually lead to serious hearing problems. Scientists generally agree that, over time, exposure to harmful levels of noise can lead to permanent noise induced hearing loss by damaging and/or destroying the inner ear's sensory hair cells.
Loud Sounds + Time = Hearing Loss
The more time you spend exposed to loud sounds, the more likely you are to damage your hearing. All of the loud sounds that you are exposed to during a day add up - continued exposure to loud sounds can prevent your ears from recovering and also cause additional damage.
Symptoms of Hearing Loss
While not all noise induced hearing loss is noticeable, symptoms may include a sensation of pressure or fullness in your ears, ringing in your ears, or muffled speech. If you experience these symptoms or believe you may have experienced noise induced hearing loss, you should have your hearing checked by an ear doctor or audiologist.
CARE & MAINTENANCE
Do not use volatile solvents (such as toluene, rosin, or alcohol) to clean this product. Such chemicals may damage it. Do not spray cleaners directly on the product. To clean this product, gently wipe it with a clean, dry, soft cloth.
