PRECAUTIONS PLEASE READ CAREFULLY BEFORE PROCEEDING Please keep this manual in a safe and handy place for future reference. WARNING Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:

Power supply Do not place the USB cable near heat sources such as heaters or radiators. Also, do not excessively bend or otherwise damage the cord, or place heavy objects on it. Do not touch the product or the power plug during an electrical storm. Use only the correct voltage specified for the product. The required voltage is printed on the name plate of the product. Use the specified USB AC adaptor (page 20). Use only the supplied USB cable/plug. Do not use the USB cable/plug for other products. Check the power plug periodically and remove any dirt or dust which may have accumulated on it. Insert the power plug firmly all the way into the AC outlet. Using the product when it is not plugged in sufficiently can cause dust to accumulate on the plug, possibly resulting in fire or skin burns. When setting up the product, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet. Even when the power switch is turned off, as long as the USB cable is not unplugged from the wall AC outlet, the product will not be disconnected from the power source. Do not connect the product to an electrical outlet using a multi-plug outlet extender. Doing so can result in lower sound quality, or possibly cause overheating in the outlet. When disconnecting the power plug, always hold the plug itself and not the cord. Pulling by the cord can damage it and cause electric shocks or a fire. If not using the product for long periods of time, be sure to pull the power plug from the AC outlet. Do not disassemble This product contains no user-serviceable parts. Do not attempt to disassemble the internal parts or modify them in any way. Water warning Do not expose the product to rain, use it near water or in damp or wet conditions, or place on it any containers

(such as vases, bottles or glasses) containing liquids which might spill into any openings or places where water may drop. A liquid such as water getting into the product may cause a fire, electric shocks, or malfunctions. Use the USB AC adaptor indoors only. Do not use in any wet environments. Never insert or remove a power plug with wet hands. Fire warning Do not place any burning items or open flames near the product, since they may cause a fire. Wireless unit Radio waves from this product may affect electro-medical devices, such as a heart pacemaker implant or defibrillator implant.

- Do not use the product near medical devices or inside medical facilities. Radio waves from this product may affect electro-medical devices.

- Do not use the product within 15 cm (6 in.) of persons with a heart pacemaker implant or a defibrillator implant. 4 YH-WL500 Owners Manual DMI-10 1/3

(Lithium ion) battery If you notice any abnormality If any of the following problems occur, immediately turn off the power switch and disconnect the power plug from the outlet. If you are using batteries, remove all batteries from the product. Finally have the device inspected by Yamaha service personnel.

- The USB cable or plug becomes frayed or damaged.

- Unusual smells or smoke are emitted.

- Some object, or water has been dropped into the product.

Doing so may result in the battery bursting, causing a fire or injury. Do not expose this product to high temperatures, such as direct sunlight or a fire. Doing so may result in the battery bursting, causing a fire or injury. Do not subject this product to mechanical shock. It may result in damage caused by batteries, electric shock, or malfunction. If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid should come in contact with your eyes, mouth, or skin, wash immediately with water and consult a doctor. Battery fluid is corrosive and may possibly cause loss of sight or chemical burns. Do not place this product in a place where the air pressure is extremely low. For details on charging the battery, be sure to read the battery manual and follow the instructions. Failure to do so may result in fire, overheating, explosion or malfunction.

CAUTION Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the product or other property. These precautions include, but are not limited to, the following:

Location

(Lithium ion) battery Charge only with a specified charger. Charging with an unspecified charger may cause leakage, overheating, explosion, or malfunction. Charge only within the specified charging temperature range. Charging at a temperature outside the range may cause leakage, overheating, explosion, or malfunction. Do not place the product in an unstable position or a location with excessive vibration, where it might accidentally fall over and cause injury. Connections Before connecting the product to other electronic components, turn off the power for all components. Also, before turning the power on or off for all components, set all volume levels to minimum. Be sure to set the volumes of all components at their minimum levels and gradually raise the volume controls while playing the product to set the desired listening level. Handling Do not rest your weight on, or place heavy objects on the product, and do not use excessive force on the buttons, switches or connectors. Keep small parts out of the reach of infants or small children who may accidentally swallow them. Do not use the product or headphones for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician. If the headphones irritate your skin, stop use immediately. Remove the power plug from the AC outlet before cleaning the unit. Failure to observe this may cause electric shocks. Before moving the product, remove all connected cables, to prevent damage to the cables or injury to anyone who might trip over them. 6 YH-WL500 Owners Manual DMI-10 3/3
