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.
