Antenna Care
Do not place a metallic shield around your adapter since it will reduce the
radio transmission efficiency.
Efficient Use
For optimum performance, please make sure that there is no metal
surrounding your adapter.
Driving
RF energy may affect some electronic systems in motor
vehicles, such as car stereo, safety equipment, etc. Check with
your vehicle manufacturer’s representative to be sure that your

•
To prevent interference with communications systems, you must

Radio Frequency Exposure
Your Class 1 USB Adapter is a radio transmitter and receiver. When in
operation, it communicates with other
Bluetooth
enabled devices by
receiving and transmitting radio frequency (RF) magnetic fields in the
frequency range 2400 to 2500 MHz. The output power of the radio
transmitter is 13.5 dBm.
You should keep your Class 1 USB Adapter at least 20 cm away from your
body during use.
The Class 1 USB Adapter is designed to be in compliance with the RF
exposure limits set by national authorities and international health
agencies when installed or used separately from other antennas or radio
transmitters.
