Precautions
On Bluetooth communications
Bluetooth wireless technology is a short-range wireless technology that enables communication between digital
devices, such as smartphones and computers. 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.
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
Because the headset achieves a tight seal over the ears, forcibly pressing it against your ears or quickly pulling it off
can result in eardrum damage. When putting on the headset, the speaker diaphragm may produce a click sound. This
is not a malfunction.
Other notes
Do not subject the headset to excessive shock as it is a precision device.
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 headset when folding.
When you use the headset as wired headphones, use the supplied headphone cable only. Make sure that the
headphone cable is firmly inserted.
