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
Power 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.
4. Emergency calls
IMPORTANT!
This Bluetooth headset and the electronic device connected to the headset operate using radio
signals, mobile and landline networks as well as user-programmed functions, which cannot
guarantee connection under all conditions. Therefore you should never rely solely upon any
electronic device for essential communications (e.g. medical emergencies). Remember, in order to
make or receive calls, the headset and the electronic device connected to the headset must be
powered on and in a service area with adequate mobile signal strength. Emergency calls may not be
possible on all mobile phone networks or when certain network services and/or phone features are
in use. Check with your local service provider.
5. Battery information
A rechargeable battery has a long service life if treated properly. A new battery or one that has
not been used for a long period of time could have reduced capacity the first few times it is used.
Do not expose the battery to extreme temperatures, never above +50°C (+122°F) or below -10°C
(+14°F). For maximum battery capacity, use the battery at room temperature. If the battery is
used in low temperatures, the battery capacity will be reduced. The battery can only be charged in
temperatures between +10°C (+50°F) and +45°C (+113°F).
6. Recycling the battery in your Bluetooth headset
The battery in your Bluetooth headset must be disposed of properly and should never be placed
in municipal waste. The LG Electronics service partner who removes the battery will dispose of it
according to local regulations.
