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
- When using a Bluetooth device (TV, laptop, etc.) other than the mobile phone, the sound quality
may be affected by the specifications and performance of the device
3. Potentially explosive atmosphere
Turn off your electronic device when in any area with a potentially explosive atmosphere. It is rare,
but 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. 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° or below -10°. For maximum battery
capacity, use the battery in 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 0° and +45°.
5. 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.
