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 meters (about 30 feet). 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. Communication System: Bluetooth Specification version 2.0 Compatible Bluetooth Profile: A2DP (Advanced Audio Distribution Profile) AVRCP (Audio/Video Remote Control Prole) (The following two profiles are headset only.)

Caution
If the headset detects a problem while charging, the headset 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 (32 F 104 F). 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.
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 AC power adaptor. Do not use any other AC power adaptor.

Precautions

On Bluetooth communication
Bluetooth wireless technology operates within a range of about 10 meters (about 30 feet). Maximum communication range may vary depending on obstacles (human body, metal, wall, etc.) or electromagnetic environment. 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 product. The following conditions may cause noise, sound break or playback speed change. When using inside the metal bag. When using inside the backpack or shoulder bag. A device using 2.4 GHz frequency, such as a wireless LAN device, cordless telephone, or microwave oven, is in use near this product. Because Bluetooth devices and wireless LAN (IEEE802.11 b/g) use the same frequency, microwave interference may occur and resulting in communication speed deterioration, noise, or invalid connection if this product is used near a wireless LAN device. In such a case, perform the following. Install this product and Bluetooth device as near to each other as possible. If this product is used within about 10 meters (about 30 feet) of a wireless LAN device, turn off the wireless LAN device. 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.
