On BLUETOOTH® communications
• 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.
• 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.

eardrum damage. When wearing the headphones, the speaker
diaphragm may produce a click sound. This is not a malfunction.

• When you use the unit as wired headphones, use the supplied
headphone cable only. Make sure that the headphone cable is firmly
inserted.
• Do not apply weight or pressure to the unit for long periods, including
when it is stored, as it may cause deformation.
