If the usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult your nearest
Sony dealer.
Avoid exposure to extreme temperature changes, direct sunlight, moisture, sand, dust, and electrical shock. Never leave the
headset in a parked vehicle.
When connecting the charging case to a computer, use only the supplied USB Type-C cable, and be sure to directly connect
them. Charging will not be properly completed when the charging case is connected through a USB hub.
The headset and the charging case may become warm during charging or for a while after charging. However, this is not a
malfunction.
