you may have interruptions, connection is disabled, or the device may be affected. Please keep the R-Talk 800EX as far away as
possible from the wireless LAN device.
 The following devices use 2.4 GHz radio waves. If any of the devices is near, you may have interruptions, or the product may stop
working. Also, the other party may be affected. Please place or use the devices as far away as possible.
• A wireless game controller,
• A factory, warehouse, or other logistics management system,
• An anti-shoplifting security gate (seen in a bookstore or CD shop),
• The identification system of a railroad vehicle or emergency vehicle,
• A wireless LAN device (a TV, video, computer, etc),
• A fire alarm system,
• A medical microwave device,
• An automatic door or other automatically controlled device,
• An amateur radio station,
• A Bluetooth-enabled device, etc.
 A wireless system in the frequency range of 2.400 to 2.4835 GHz is built in the R-Talk 800EX and cannot
avoid the bandwidth of devices used for identifying mobile objects.The modulation method is "FH-SS" and
the interference distance is 10 meters.
The information is available on the mark shown to the right.The mark is attached to the R-Talk 800EX.
*Bluetooth is a trademark of Bluetooth SIG, Inc. NTT Advanced Technology is licensed to use the trademark.
