This Bluetooth Wireless Stereo Headset HBS-820 is a radio transmitter and receiver. When in
operation it communicates with a Bluetooth equipped mobile device by receiving and transmitting
radio frequency (RF) electromagnetic fields (microwaves) in the frequency range 2.4 to 2.4835 GHz.
Your Bluetooth headset is designed to operate in compliance with the RF exposure guidelines and
limits set by national authorities and international health agencies when used with any compatible
LG Electronics mobile phone.
2. Bluetooth connection precautions
The following environments affect the range and reception of Bluetooth signals:
- When walls, metal, human bodies, or other obstacles exist between the Bluetooth device and
the connected device.
- When equipment that uses 2.4 GHz frequency signals (Wireless LANs, wireless phones,
microwave ovens, etc.) is placed near the devices being used.
3. Potentially explosive atmosphere
Turn off your electronic device when in any area with a potentially explosive atmosphere. Although
this is uncommon, your electronic device could generate sparks. Sparks in such areas could cause
an explosion or fire resulting in bodily injury or even death. Areas with a potentially explosive
atmosphere are often, but not always, clearly marked.
