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 or disable Wi-Fi immediately.
