Bluetooth Wireless Technology

With the Bluetooth wireless technology, you can connect the earphone to its compatible communication devices without

the maximum distance between them cannot exceed 10 meters (about 30 feet). The Bluetooth wireless connection may be

interfered by obstacles (such as walls) or other electronic devices.

In some areas, use of the Bluetooth wireless technology may be subject to some constraints. Please consult your local

authority or service provider for details.

Please fully charge the headset before use (refer to the Charging Instructions section of this book for charging instructions).

Select a mobile phone or other Bluetooth terminal device compatible with the headset for pairing (refer to the Basic

Operations for the pairing method).

Tips: Do not use credit cards or other magnetic storage media close to the headset to avoid losing storage information due

to degaussing.
