What is Bluetooth wireless technology?
BluetoothTM 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.) HSP (Headset Profile)*: Talking on the phone/ Operating the phone. HFP (Hands-free Profile)*: Talking on the phone/ Operating the phone by hands-free.
* When you use a Bluetooth mobile phone supported by both HFP (Hands-free Profile) and HSP (Headset Profile), set to HFP.

What is Bluetooth wireless technology?
BluetoothTM 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.

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.

Maximum communication time or standby time may vary depending on your iPod.
To listen to music from the headphone jack of the iPod, disconnect the transmitter from the iPod. While the transmitter is turned on, it consumes power from the iPod. We recommend disconnect the transmitter from iPod when not using the Bluetooth function. If the headphone is connected to the iPod while the iPod is playing back, it consumes power from iPod. If you turn off the transmitter while the iPod is playing back, iPod will power off. It is not recommended to turn off iPod as the linkage will lost between the transmitter and the Bluetooth receiving device. There is no need to charge the transmitter as it will receive power from the connected iPod. It is recommended to check the iPods remaining battery before using.
