6. Cautions
This device uses ultra high frequency radio. Therefore if there’s an object like concrete wall or furniture
etc, between USB dongle and receiver device, the radio performance will be decreased much. Any
obstacle objects should not be between USB dongle and receiver. The operating range is 5~10m and it
can be varied according the environment.
