Charging basics
A complete charging cycle takes about 1.5 hours. Before using the earphones for
the first time, charge their rechargeable battery for a complete charging cycle
without interruption.
When the battery is almost empty or when the earphones are being charged,
the LED lights up or flashes as indicated in the table below and a voice prompt
announces the charge condition of the battery. When the battery charge drops
to a low level, a voice message prompts you to recharge the earphones to avoid
call and music disruptions.
It is recommended to charge the earphones using only the supplied USB cable.
If you are charging using an external USB-power adapter, it is recommended to
use an adapter with an output rating of 500 mA or higher.

Pairing the earphones
CAUTION
Danger of malfunction!
The transmitted radio waves of mobile phones can impair the
operation of sensitive and unprotected devices.
XOnly make calls with the earphones in locations where Bluetooth
wireless transmission is permitted.
The M2 IEBT earphones comply with the Bluetooth 4.0 standard. In order that
data can be transmitted wirelessly using Bluetooth technology, you have to pair
your earphones with compatible Bluetooth devices that support the following
profiles:
XHands Free Profile (HFP)
XAudio/Video Remote Control Profile (AVRCP)
XAdvanced Audio Distribution Profile (A2DP)
When you switch the earphones on, they automatically try to connect to the
last two connected Bluetooth devices. The earphones can save the connection
profiles of up to eight Bluetooth devices with which they have been paired.
If you pair the earphones with a ninth Bluetooth device, the saved connection
profile of the least used Bluetooth device will be overwritten. If you want to
re-establish a connection with the overwritten Bluetooth device, you have to
pair the earphones again.
You can easily pair and connect your wireless earphones with your smartphone
if the device supports the Near Field Communication (NFC) technology.
