Devices
Handset Bluetooth
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

by device.
If the problem persists, power off Bluetooth

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.
