Bluetooth xx Bluetooth is a technology for wireless communication between devices within an area of about 10 meters (33 ft.) employing the 2.4 GHz frequency band, a band which can be used without a license. xx Bluetooth is a registered trademark of the Bluetooth SIG and is used by Yamaha in accordance with a license agreement. Handling Bluetooth communications xx The 2.4 GHz band used by Bluetooth compatible devices is a radio band shared by many types of equipment. While Bluetooth compatible devices use a technology minimizing the influence of other components using the same radio band, such influence may reduce the speed or distance of communications and in some cases interrupt communications. xx The speed of signal transfer and the distance at which communication is possible differs according to the distance between the communicating devices, the presence of obstacles, radio wave conditions and the type of equipment. xx Yamaha does not guarantee all wireless connections between this unit and devices compatible with Bluetooth function. Do not use this unit within 22 cm (9 inches) of persons with a heart pacemaker implant or defibrillator implant. Radio waves may affect electro-medical devices. Do not use this unit near medical devices or inside medical facilities. Caution Regarding the Waterproofing The earphones of this product feature a water-resistant design that allows them be used even if they are exposed to a certain amount of rain or sweat, but please be aware of the following precautions. xx Do not allow large amounts of water to contact the earphones. If the earphones are exposed to a large amount of water, let them dry out in a dry location for at least one day before using them. When letting them dry, do not use a hair drier or similar device, since this may cause the earphones to malfunction or to become deformed. xx Do not place the earphones in water. They may malfunction if they fall into water. xx If a large amount of sweat or water droplets should adhere to this product, wipe it off with a dry cloth as soon as possible. xx Do not allow the L-shaped plug or the Bluetooth receiver to get wet. Since the L-shaped plug and the Bluetooth receiver are not waterresistant, doing so could cause malfunctions. Malfunctions caused by water entering the earphones due to incorrect handling will not be covered by the warranty even if the warranty period is still in effect. 9 En
