FAQ

#### Why is my BLUETOOTH(R) connection slow?

- Data transfer speed depends on obstructions and/or the distance between the two devices, radio wave quality, and the device configuration or software in use.
  Move your VAIO computer and BLUETOOTH device closer to each other.

- If a version of a BLUETOOTH standard employed on the BLUETOOTH device with which you want to communicate is not the same version as the one employed on your VAIO computer, the communication speed may become slower.

- When your VAIO computer is equipped with BLUETOOTH Core Specification Version 2.1 + EDR, if both the BLUETOOTH function and the wireless LAN function are enabled, interference may occur resulting in slower communication speed or other problems.

- Your VAIO computer and BLUETOOTH devices need to be compliant with BLUETOOTH Core Specification Version 3.0 + HS for high-speed communication between them. Furthermore, enable both the wireless LAN and BLUETOOTH functions on the computer beforehand. Some BLUETOOTH profiles do not support high-speed communication.
