To turn on the transmitter

Power button

Connect the transmitter to the Walkman, then the power of the transmitter will turn on automatically. If the power of the transmitter is off while the transmitter is connected to the Walkman, press and hold the transmitters power button for about 2 seconds to turn it on. When the transmitter turns on, the transmitter indicator flashes twice.
To turn off the transmitter
To turn off the transmitter, press and hold the transmitters power button for about 2 seconds. The transmitter indicator flashes once and the transmitter turns off. ip T
Maximum communication time or standby time may vary depending on your Walkman. For details, access the following URL: Europe: http://www.sonydigital-link.com/DNA/ Latin America: http://www.sony-latin.com/index.crp
To listen to music from the headphone jack of the Walkman, disconnect the transmitter from the Walkman. While the transmitter is turned on, it consumes power from the Walkman. We recommend turning off the transmitter when not using the Bluetooth function. If you turn off the transmitter while the Walkman is playing back, playback will stop. There is no need to charge the transmitter as it will receive power from the connected Walkman. It is recommended to check the Walkmans remaining battery before using. Depending on the Walkman model, you may not be able to connect the headphone to it when the transmitter is connected to the Walkman.

About the MODE switch on transmitter
You can select the sound quality or wireless communication stability preferentially. MODE 1: Sound quality takes priority. MODE 2: Reception stability takes priority.
When you set the MODE switch to MODE 1, and experience sound breaks, set to MODE 2. Sound break may occur depending on your Bluetooth receiving device when switching between MODE 1 and 2.
Controlling a Walkman with the headset
You can control a Walkman using the control button of the headset. Before starting remote control operation, check that step 1 and 2 of Listening to music of the Walkman are completed (page 14).

What is Bluetooth technology?
Bluetooth wireless technology is a shortrange 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. You do not need to use a cable for connection since Bluetooth technology is a wireless technology, 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 technology is an international standard supported by thousands of companies all over the world, and employed by various companies worldwide.

Precautions

On Bluetooth communication
Bluetooth wireless technology operates within a range of about 10 meters. Maximum communication range may vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment.

Optimal performance Limited performance
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.
Profile is standardization of the function for each Bluetooth device specification. This product supports the following Bluetooth version and profiles:

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.
If this product is used within about 10 meters of a wireless LAN device, turn off the wireless LAN device. Due to the characteristic of Bluetooth wireless technology, the sound played on the headset is slightly delayed from the sound played on the Walkman. W e do not take any responsibility for 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, 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. Depending on the device to be connected, communication may take some time.
