# Notes on Using the Bluetooth Function

- Use of Bluetooth function may be restricted by local regulations in some countries or regions.

- The Bluetooth function may not work with some devices, depending on the manufacturer or the software version employed by the manufacturer. Check the system requirements of the Bluetooth device before purchasing.

Some Bluetooth devices require authentication (pairing) before establishing a connection with another device. Perform the authentication process before connecting to such a device.

- Bluetooth devices work on the 2.4 GHz band, which is used by a variety of devices. Bluetooth devices use technology to minimize radio interference from other devices that use the same band. However, radio interference may still cause slower data transfer speeds, reduce communications range or cause communications failure.

- Data transfer speed and communications range may vary depending on the following conditions:

- Distance between communicating devices

- Presence of obstacles between devices

- Surrounding environment (wall material, etc.)

- Device configuration

- Software in use

- Signal conditions

- Communications failure may occur in some signal conditions.

- Interference may occur if both the Bluetooth function and the 2.4 GHz Wi-Fi function are enabled. That will result in slower data transfer speeds or other problems.

- Large files may occasionally be corrupted during continuous transfer due to limitations of the Bluetooth standard and due to signal conditions.

- Connecting multiple Bluetooth devices to your tablet device may cause channel congestion, resulting in poor device performance. This is normal with Bluetooth technology and does not indicate a malfunction.

- Video and audio may not be synchronized if you play videos on your tablet device with audio output from a connected Bluetooth device. This is a frequent occurrence with Bluetooth technology and does not indicate a malfunction.

- All Bluetooth devices must be certified through procedures stipulated by Bluetooth SIG to ensure that they comply with the Bluetooth standard. Even if the Bluetooth standard is complied with, operation procedures may differ or you may not be able to transfer data depending on characteristics and specifications of the individual device.

- Output sound may not be switched between a Bluetooth audio device and the built-in speaker when you connect or disconnect the device while an app such as game is running. If that occurs, exit the app and restart the device. You can avoid this problem by switching the sound before starting the app.

- Sound of apps such as games may be delayed when heard from Bluetooth audio devices connected to your tablet device. If that occurs, output sound from the built-in speaker or connect an audio device to the headphone jack of your tablet device to hear the sound.

- If you turn off a Bluetooth audio device connected to your tablet device while an app such as a game is running, the app may no longer work properly. If that occurs, exit the app and restart your tablet device.

## Bluetooth security

Bluetooth wireless technology has an authentication function that allows you to determine with whom you choose to communicate. With the authentication function, you can prevent any anonymous Bluetooth devices from accessing your tablet device. The first time two Bluetooth devices communicate, a common passkey (a password required for authentication) should be determined for both devices to be registered. Once a device is registered, there is no need to re-enter the passkey.
Your tablet device will be detected by other Bluetooth devices only when it is set to allow detection by such devices. You can set how long your tablet device is detectable or whether or not to allow reception after a connection is established.
