What is Bluetooth wireless technology?
Bluetooth wireless technology is a short-range wireless technology that enables wireless data communication between digital devices, such as a computer or digital camera. Bluetooth wireless technology operates within a range of about 10 metres. Connecting two devices as necessary is common, but some devices can be connected to multiple devices at the same time. You do not need to use a cable for connection, nor is it necessary for the devices to face one another, such is the case with infrared technology. For example, you can use such a device in a bag or pocket. Bluetooth standard is an international standard supported by thousands of companies all over the world, and employed by various companies worldwide.
HSP (Headset Profile)*2: Talking on the phone/Operating the phone. HFP (Hands-free Profile)*2: Talking on the phone/Operating the phone by hands-free. *1 Enhanced Data Rate *2 When you use a Bluetooth mobile phone supported by both HFP (Hands-free Profile) and HSP (Headset Profile), set to HFP. Notes To be able to use the Bluetooth function, the Bluetooth device to be connected requires the same profile as the units. Note also that even if the same profile exists, devices may vary in function depending on their specifications. Due to the characteristic of Bluetooth wireless technology, the sound played on this unit is slightly delayed from the sound played on the Bluetooth device during talking on the telephone or listening to the music.
Communication System and Compatible Bluetooth Profiles of this unit
Profile is standardization of the function for each Bluetooth device specification. This unit supports the following Bluetooth version and profiles:
Communication System : Bluetooth Specification version 2.1 + EDR*1 Compatible Bluetooth Profiles: A2DP (Advanced Audio Distribution Profile): Transmitting or receiving audio content of high-quality. AVRCP (Audio Video Remote Control Profile): Controlling A/V equipment; pausing, stopping, starting playback, volume control, etc.

Open the cover of the USB () jack. Connect the supplied USB () cable to the unit, and then connect the other end to a computer. When connecting, insert the connector with facing down.
Tips If the USB cable is connected to a computer while the unit is turned on, the unit will be turned off automatically. To charge the unit from an AC outlet, use the USB charging AC power adaptor ACU50A (sold separately*). For details, refer to the manuals supplied with the USB charging AC power adaptor. This unit cannot be turned on while charging. *The above optional accessory is not provided in some areas.
Charging starts when the unit and the computer are connected. Make sure that the indicator (red) lights up. Charging is completed in about 2.5 hours* and the indicator (red) goes off automatically.
*Time required for empty battery to recharge. Notes If this unit is not used for a long time, the indicator (red) may not light up when you connect the USB cable to charge this unit. In this case, do not disconnect the USB cable from the unit and wait until the indicator (red) lights up. When you close the cover of the USB () jack after charging, push the cover thoroughly until the tab is full inserted. For system requirements for a personal computer that can charge the battery using USB, see the Specifications (page 29).
If this unit detects a problem while charging, the indicator (red) may turn off, although charging is not complete. Check for the following causes: Ambient temperature exceeds the range of 0 C 40 C. There is a problem with the battery. In this case, charge again within the above-mentioned temperature range. If the problem persists, consult your nearest Sony dealer.
Notes If the battery is not used for a long time, battery may be quickly depleted, however, after a few recharges, battery life will improve. If the life of the built-in rechargeable battery drops to half the normal length, the battery should be replaced. Consult your nearest Sony dealer for replacement of the rechargeable battery. Avoid exposure to temperature extremes, direct sunlight, moisture, sand, dust or mechanical shock. Never leave in a car parked in the sun. Use only the supplied USB cable. Do not use any other USB cable. If the computer enters into hibernation mode while connected to the unit, charging will not be completed properly. Check the setting of the computer before charging. The indicator (red) will go off automatically even if the computer enters into hibernation mode. Charge the unit again in this case. Use the supplied USB cable only, and connect directly to a computer. Charging will not be completed properly by an indirect connection, such as via a USB hub.

ADDITIONAL INFORMATION

Precautions
On Bluetooth communication Bluetooth wireless technology operates within a range of about 10 metres. Maximum communication range may vary depending on obstacles (human body, metal, wall, etc.) or electromagnetic environment. The aerial is built into the unit as illustrated in the dotted line. The sensitivity of the Bluetooth communication will improve by turning the direction of the built-in aerial to the connected Bluetooth device. The communication distance shortens when the obstacles are between the aerial of the connected device and this unit. Use this unit at least 10 m away from the wireless LAN device. If this unit is used within 10 m of a wireless LAN device, turn off the wireless LAN device. Install this unit and Bluetooth device as near to each other as possible. 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: where inflammable gas is present, in a hospital, train, airplane, or a petrol station near automatic doors or a fire alarm This unit supports security capabilities that comply with the Bluetooth standard to provide a secure connection when the Bluetooth wireless technology is used, but security may not be enough depending on the setting. Be careful when communicating using Bluetooth wireless technology. We do not take any responsibility for the leakage of information during Bluetooth communication. Connection with all Bluetooth devices cannot be guaranteed. A device featuring Bluetooth function is required to conform to the Bluetooth standard specified by Bluetooth SIG, Inc. and be authenticated. Even if the connected device conforms to the above mentioned Bluetooth standard, some devices may not be connected or work correctly, depending on the features or specifications of the device. While talking on the phone hands free, noise may occur, depending on the device or communication environment. Depending on the device to be connected, it may require some time to start communication.
