Bluetooth 4.0 USB Micro 
Adapter Multi-Language 
Version
The IOGEAR Bluetooth 4.0 USB Micro Adapter offers Bluetooth connectivity at a fraction of the size of normal Bluetooth USB 
adapters. About the size of an adult fingernail, the IOGEAR Bluetooth 4.0 USB Micro Adapter allows users to connect to all the latest 
Bluetooth devices like cell phones, PDAs, mice, keyboards and more. Because the IOGEAR Bluetooth 4.0 Micro Adapter is so small 
you can easily plug it into your computer without blocking any surrounding USB ports.
The IOGEAR Bluetooth 4.0 Micro Adapter allows users to connect up to three Bluetooth devices together and transfer even the 
largest files quickly and easily. With the Micro Adapter's lower power consumption, you can enjoy longer battery life on your notebook 
computer and other devices. This Bluetooth Class 2 adapter is compatible with PC computers, and offers a wireless range of 30 feet 
(10 meter). It is great for a wide range of applications and smaller form factor devices in the healthcare, fitness, security and home 
entertainment industries.
