Notes on Using the Wi-Fi Function

Use of Wi-Fi products may be restricted by local regulations in some countries or regions.
Wi-Fi devices work on the 2.4 GHz band, which is used by a variety of devices. Wi-Fi 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.
If both the Bluetooth function and the 2.4 GHz Wi-Fi function of your tablet device are enabled, interference
may occur and cause slower data transfer speeds or other problems.
To communicate via Wi- Fi while traveling, you may need to contract with a Wi-Fi connection service provider.
Data transfer speed and communications range may vary depending on the following conditions:

Distance between devices
Presence of obstacles between devices
Device configuration
Signal conditions
Surrounding environment (wall material, etc.)

Software in use
Communications may be cut off depending on signal conditions.
The data transfer rate specified in the specification is the theoretical maximum, and may not reflect actual
data transfer rate.
Actual data transfer speed may not be as fast as the speed displayed on your tablet device.
Communications is not available between the 2.4 GHz and 5 GHz Wi-Fi frequency bands.
The data transfer rate for IEEE 802.11g and IEEE 802.11n (2.4 GHz) devices may be affected by interference
when used with IEEE 802.11b products. Also, products using IEEE 802.11g and IEEE 802.11n automatically
lower the transfer rate to maintain compatibility with IEEE 802.11b products.
When the data transfer speed is not as fast as expected, changing the wireless channel on the access point
may increase the speed.

About Bluetooth(R) 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 other
Bluetooth devices. You can set the time to accept the detection, or whether or not to allow reception after both
devices are connected.
