Reception Interference Caused by Wi-Fi (WLAN)
Devices
Handset Bluetooth
®
function uses the same frequency band (2.4 GHz) as Wi-Fi (WLAN) devices.
Using near Wi-Fi (WLAN) devices may cause radio interference, low-communication speed, noise or
connection failure. In that case, take the following measures.

Provide distance between Bluetooth
®
device and Wi-Fi (WLAN) device. Required distance varies
by device.

If the problem persists, power off Bluetooth
®
device or Wi-Fi (WLAN) device.
Wi-Fi (WLAN)

Wi-Fi (WLAN) uses radio waves to exchange information and LAN connection is freely established
within an area where the radio wave reaches. Meanwhile, if no security is set, Wi-Fi
communications may be intercepted or hacked by malicious parties. It is recommended to make
necessary security settings on your responsibility.

Use handset WLAN function only in Japan.

Do not use Wi-Fi near magnetic devices such as electrical appliances or AV/OA devices.
Magnetic/radio waves may hinder or disable communication. Avoid microwave ovens especially.
Using near a TV or radio, etc. may cause interference; may affect TV reception.

If there are multiple Wi-Fi access points using the same channel, search may fail.

Enable Wi-Fi to search available Wi-Fi networks and then establish connection.

Connect to Wi-Fi network before accessing Internet via Wi-Fi (WLAN).

Take care with radio signal strength for Wi-Fi (WLAN). Radio signal strength for Wi-Fi network
differs depending on the access point location. Moving close to a Wi-Fi router may improve radio
signal strength.

To save battery power, disable Wi-Fi (WLAN) when not used.
