Wi-Fi (Wireless LAN)

Wireless LAN (hereafter "Wi-Fi") uses radio waves to enable communication between compatible

devices within range. However, it is advisable for the user to configure security settings to avoid risk

of data interception.

 Do not use Wi-Fi near electrical appliances, audiovisual equipment or office automation

equipment; may affect Wi-Fi transmission speed, availability, clarity, etc. (Especially when a

microwave oven is in use.)

 If there are multiple access points nearby, handset may not detect access points correctly.

■Precautions

The frequency band utilized by handset Wi-Fi is shared with industrial, scientific or medical

equipment, including household microwave ovens, and used by radio stations, amateur radio

stations, etc. (hereafter "other radio stations").

1. Before using Wi-Fi, visually check that no other radio stations sharing the same frequency band

are in use nearby.

2. Should interference occur between handset and other radio stations, move it to a different location

or disable Wi-Fi immediately.

■Simultaneous Use with Bluetooth

Wi-Fi (IEEE 802.11b/g/n) and Bluetooth

transmit on the 2.4 GHz band. Enabling handset Bluetooth

or using Bluetooth

devices near handset may affect Wi-Fi transmission speed, availability and

clarity. Should interference occur, cancel handset Bluetooth

or discontinue Bluetooth

device use.
