The maximum communication distance may vary depending on the presence of obstacles (people, metal objects, walls, etc.) or the electromagnetic environment. Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off this unit and other Bluetooth devices in the following locations, as it may cause an accident: in hospitals, near priority seating in trains, locations where inflammable gas is present, near automatic doors, or near fire alarms. When you use the headset on an airplane, follow the instructions of cabin attendants or ask the airline you fly with about conditions for using the headset. If you do not use the supplied headphone cable, radio waves may affect instruments, causing risk of accident due to malfunction. Be sure that you use the supplied headphone cable on an airplane. The audio playback on this unit may be delayed from that on the transmitting device, due to the characteristics of Bluetooth wireless technology. As a result, the sound may not be in sync with the image when viewing movies or playing games. The unit supports security functions that comply with the Bluetooth standard as a means of ensuring security during communication using Bluetooth wireless technology. However, depending on the configured settings and other factors, this security may not be sufficient. Be careful when communicating using Bluetooth wireless technology. Sony shall assume no responsibility for any damages or loss resulting from information leaks that occur when using Bluetooth communications. Bluetooth connections with all Bluetooth devices cannot be guaranteed. Bluetooth devices connected with the unit must comply with the Bluetooth standard prescribed by Bluetooth SIG, Inc., and must be certified as compliant. Even when a connected device complies with the Bluetooth standard, there may be cases where the characteristics or specifications of the Bluetooth device make it unable to connect, or result in different control methods, display, or operation. When using the unit to perform hands-free talking on the phone, noise may occur depending on the connected device or the communication environment. Depending on the device to be connected, it may require some time to start communications. Note on static electricity Static electricity accumulated in the body may cause mild tingling in your ears. To reduce the effect, wear clothes made from natural materials, which suppress the generation of static electricity. Notes on wearing the unit Because the headphones achieve a tight seal over the ears, forcibly pressing them against your ears or quickly pulling them off can result in eardrum damage. When wearing the headset, the speaker diaphragm may produce a click sound. This is not a malfunction. Other notes Do not subject the unit to excessive shock. The touch sensor may not operate properly if you apply stickers or other adhesive items to the touch sensor control panel. Be careful not to catch your finger in the unit when folding. When you use the unit as wired headphones, use the supplied headphone cable only. Make sure that the headphone cable is firmly inserted. 118
