Bluetooth connection
The wireless Bluetooth technology works within a range of approx. 10 m and its effectiveness
can vary due to obstacles or the electromagnetic environment.
The Bluetooth connection can be interrupted and cause noise, audio loss or communication faults:
• There is someone between the headphones and the Bluetooth device.
• There are obstacles (e.g. metal items or a wall) between the headphones and the Bluetooth
device.
• Devices with a frequency of 2.4 GHz (e.g. WiFi devices, cordless telephones or microwaves)
are being used in the vicinity of the headphones.
Bluetooth devices and WiFi devices use the same frequency, so microwave interference may
occur if the headphones are used near a WiFi device. If this happens, do the following:
• When using the headphones, make sure they are at least 10 m away from WiFi devices.
• When using the headphones within 10 metres of a WiFi device, switch off the WiFi device.
• Position the headphones and the paired Bluetooth device as closely together as possible.
The microwaves emitted by Bluetooth devices can affect the functioning of medical electronic
devices. To avoid accidents, turn off this unit and other Bluetooth devices in the following
locations:
• Places where flammable gases are stored (e.g. hospitals or fuel stations).
• In the vicinity of automatic doors or fire alarms.
• Always use the audio cable provided when using the headphones on an aeroplane.
Due to the nature of wireless technology, there is a delay between sounds/music played on the
headphones and the device sending the sounds/music. As a result, when you watch movies or
play games the sound may be out of sync.
We accept no responsibility for information that may be disclosed while connecting via Blue-
tooth.
Successful connection to all Bluetooth devices cannot be guaranteed.
