2.9 Safety notices for WLAN and Bluetooth operation
• The radio waves necessary for WLAN and Bluetooth can cause interference in hearing aids
(unpleasant buzzing) and in the onboard electronics of vehicles. To prevent interference,
switch off the device in aircraft, or when driving a vehicle.
• Radio waves caused by WLAN and Bluetooth may lead to malfunctioning of life-support
systems. Switch off the WLAN and Bluetooth function if you are in the proximity of such
systems, e.g. hospitals, medical electronic systems.
• The range of the wireless connection and the achievable data transmission rate depend on
the ambient and environmental conditions.
• A WLAN and Bluetooth connection is not tap-proof. Unauthorized third parties can then
receive data.
To protect the transmitted data, WLAN and Bluetooth have different encryption methods.
We recommend that you activate an encryption in accordance with your WLAN and
Bluetooth environment.
• If possible, do not bring the WLAN and Bluetooth connection in the vicinity of the
following devices as the operation of these devices may result in faults or the complete
failure of the WLAN and Bluetooth connection:
– Microwaves
– Wireless video-audio transmission systems
– Wireless telephones (DECT)
Risk of interference with pacemakers
The radio waves of WLAN and Bluetooth may interfere with pacemakers.
If you wear a pacemaker, keep a minimum distance of 20 cm from the device when WLAN
or Bluetooth is activated.
Danger of explosion
The radio waves transmitted by WLAN and Bluetooth may trigger an explosion or fire.
Switch off WLAN and Bluetooth of the device if you go in the vicinity of flammable gases or
in an explosive environment (e.g. paint shop).
