9. Bluetooth Communication
The effective range of Bluetooth communication is 10 m orless in an unobstructed space. If there is an obstacle suchas a wall between Bluetooth devices, the range ofcommunication will be shorter. Interference may be caused
near the following devices that use the 2.4 GHz frequency
band, which is the same as for Bluetooth. Therefore, thisdevice is not suited for uses that require reliability.
Wireless LAN
Bluetooth devices (such as PC, tablets, smart phones, etc.)
Home appliances such as microwave ovens

10. Installation of Driver Software
The driver software is automatically installed with Windows
8.1 or later. If the driver cannot be installed, download thesoftware from [Support] - [Software] of the A&D website.
