Hint To check the battery states of the receiver and the microphone, open the lid of the charging case and see the indication of each power lamp. For details, see Lamp indications. To charge the built-in battery of the receiver with the USB Type-C cable You can alternatively charge the built-in battery of the receiver without using the charging case as described below. 1. Open the lid of the USB Type-C port and connect a USB Type-C cable to the port. 2. Connect the cable to a power source, such as a computer that is up and running, for battery charging. The power lamp on the receiver lights in orange. 3. When battery charging is finished, disconnect the USB Type-C cable from the receiver. Wait until the power lamp goes out to indicate that charging is finished (the battery is fully charged). Note Do not apply excessive force to the receiver when you connect the receiver to a computer. This may cause damage to the receiver or the computer. Connecting the receiver to a laptop computer that is not connected to an AC power source may deplete the battery power of the computer. Do not leave the receiver connected to the computer for an extended period of time. Use of any customized or hand-built computer is not guaranteed for battery charging or for connection with the receiver. Depending on the type of USB device used in combination with the receiver, the receiver may fail to operate. Not all the computers are guaranteed for operation with the receiver. Battery charging via the USB connection may not be possible when the connected computer goes into standby (sleep) or hibernate mode. If this is the case, change the computer settings and then charge the battery all over again. In the event that this unit is kept unused for an extended period of time, the amount of power that each rechargeable battery can charge may be reduced. To make the battery capable of charging sufficient power, let the battery charge and discharge the power repeatedly for a few times. In the event that you store this unit for an extended period of time, charge the batteries once every 6 months to protect them against over-discharging. In the event that this unit is kept unused for an extended period of time, it may take longer to charge the built-in batteries. In the event that any of the rechargeable batteries of this unit fails and the failure is detected while battery charging is in progress, the charging lamp on the charging case stays blinking in orange. It is recommended that the battery be charged when the ambient temperature is in the range of 15 °C to 35 °C (59 °F to 95 °F). Efficient battery charging may not be possible when the temperature is outside this range. If the failure persists, consult your nearest Sony dealer. In the event of charging the built-in batteries after this unit is kept unused for an extended period of time, the power lamp or the charging lamp may not immediately light in orange. Wait for a while until the power lamp or the charging lamp lights in orange. A significantly short battery life indicates that the rechargeable battery should be replaced with a new one. Consult your nearest Sony dealer. Keep this unit against exposure to extreme temperature changes, direct sunlight, moisture, sand, dust, and electrical shocks. Never leave this unit in a parked vehicle. When connecting the receiver or the charging case to a computer, be sure to use only the USB Type-C cable and connect them directly. Indirect connection, for example, via a USB hub fails to charge the built-in battery. Related Topic Lamp indications 11
