Pairing the headphones
CAUTION
Danger of malfunction!
The transmitted radio waves of mobile phones can impair the
operation of sensitive and unprotected devices.
X Only make calls with the headphones in locations where Bluetooth
wireless transmission is permitted.
The CX 7.00BT In-Ear Wireless headphones comply with the Bluetooth 4.1
standard. In order that data can be transmitted wirelessly using Bluetooth
technology, you have to pair your headphones with compatible Bluetooth
devices that support the following profiles:
X Hands Free Profile (HFP)
X Audio/Video Remote Control Profile (AVRCP)
X Advanced Audio Distribution Profile (A2DP)
When you switch the headphones on for the first time, they automatically go to
pairing mode. If the headphones have already been paired with a few devices,
they automatically try to connect to the most-recently connected Bluetooth
device when switched on. The headphones can save the connection profiles of
up to eight Bluetooth devices or smartphones.
If you pair the headphones 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 headphones again.
You can easily pair and connect your wireless headphones with your smartphone if the device supports the Near Field Communication (NFC) technology.

Troubleshooting
Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible in the Bluetooth transmission
range of your smartphone. The transmission range largely depends on
environmental conditions such as wall thickness, wall composition etc. With a
free line of sight, the transmission range of most smartphones and Bluetooth
devices is up to 10 meters.
If the headphones leave the Bluetooth transmission range of the smartphone,
the sound quality deteriorates and you hear the voice prompt “lost connection”.
At this point, the connection breaks down completely. You can re-establish the
connection if you re-enter the Bluetooth transmission range and you hear the
voice prompt ”connected”.
X To re-establish the connection, press the play/pause button.
Clearing previously paired devices
X Set the headphones to pairing mode, see page 16.
The LED flashes blue and red. The headphones are in pairing mode.
X Simultaneously press the play/pause button and the power button for
4 seconds.
The LED flashes purple 3 times. The headphones are permanently disconnected
from all devices and immediately go into pairing mode.
