Notes on Wi-Fi
The following are notes regarding use of Wi-Fi.
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 rates,
reduce communications range, or cause communications failure.
If both the Wi-Fi function and the Bluetooth function of your Walkman are enabled,
interference may occur and cause slower data transfer rates or other problems.
To communicate via Wi-Fi while traveling, you may need to contract with a Wi-Fi
connection service provider.
Data transfer rate 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 specifications is the theoretical maximum, and it
may not reflect actual data transfer rate.
Actual data transfer rate may not be as fast as the rate displayed on the screen.
Communications is not available with 5 GHz Wi-Fi as it uses a different frequency band.
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. The normal transfer rate may be regained by
changing the channel settings of your access point.
When the data transfer rate is not as fast as expected, changing the wireless channel on
the access point may increase the rate.
The Wi-Fi antenna is built in to your Walkman. If you cover the antenna with your hands
or other objects while using the Wi-Fi function, the Wi-Fi connection may deteriorate.
