Help Guide Wireless Stereo Headset WF-C500 Precautions On Bluetooth communications Bluetooth wireless technology operates within a range of about 10 m (30 feet). 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 the headset 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. This product emits radio waves when used in wireless mode. When used in wireless mode on an airplane, follow flight crew directions regarding permissible use of products in wireless mode. The audio playback on the headset 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 headset 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 headset 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 headset 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. The headset does not support multipoint connection. If the headset supports the multipoint function, the headset can connect to a music playback device (A2DP profile, Walkman®, etc.) and a communication device (HFP or HSP profile, smartphone, etc.) at the same time, and you can listen to music while waiting for an incoming call or making a call. Note on temperature rise While charging the headset or charging case, or when using the headset for a long time, the temperature of the headset or charging case may rise, but this is not a malfunction. Note on static electricity If you use the headset when the air is dry, you may experience discomfort due to static electricity accumulated on your body. This is not a malfunction of the headset. You can reduce the effect by wearing clothes made of natural materials that do not easily generate static electricity. Notes on wearing the headset After use, remove the headset from your ears slowly. Because the earbud tips achieve a tight seal in the ears, forcibly pressing them in or quickly pulling them out can result in eardrum damage. When putting on the headset, the speaker diaphragm may produce a click sound. This is not a malfunction. 89
