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
is permitted.
The HD 4.40BT Wireless headphones comply with the Bluetooth 4.0 standard.
In order that data can be transmitted wirelessly using Bluetooth, you have to
pair your headphones with a compatible Bluetooth device that supports the
following profiles:
X Hands Free Profile (HFP)
X Headset Profile (HSP)
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.
You can instantly pair the headphones with your device if the device supports
NFC.
