About the Bluetooth(R) Function
You can establish wireless communications between your tablet device and other Bluetooth devices such as a
computer, mobile phone, headset, Bluetooth headphone or wireless keyboard.
You can transfer data between these devices without cables at a range of up to 33 feet / 10 meters in an open
area. One Bluetooth device can connect with up to seven devices via wireless network to exchange data.
When a device requires connection to another device, it sends out an inquiry to neighboring Bluetooth devices. If
any device responds to the inquiry, the two devices can connect with each other.
