Radio and Electromagnetic Interference
Radio interference can be generated by every device that emits elec-
tromagnetic signals. With so many devices transmitting and receiving
radio waves, interference can occur when radio waves overlap.
• Do not use the FRITZ!Box in places where the use of radio devices is
prohibited.
• Follow any instructions to switch off radio devices – especially in
hospitals, outpatient treatment centers, medical practices, and oth-
er medical facilities – in order to prevent interference with sensitive
medical equipment.
• Consult your doctor and the manufacturer of your medical device
(pacemaker, hearing aid, electronically controlled implant, etc.)
to find out whether it could be affected by interference from your
FRITZ!Box.
• If applicable, maintain the recommended minimum distance of
15 cm recommended by the manufacturers of medical devices in
order to prevent malfunctions of your medical device.
Potentially Explosive Environments
Under unfavorable conditions, radio waves in the vicinity of explosive
environments can cause fires or explosions.
• Do not install and operate your FRITZ!Box in the vicinity of explo-
sive environments, flammable gases, areas in which the air con-
tains chemicals or particles like grain, dust or metal powder, or in
the vicinity of detonation grounds.
• In locations with potentially explosive atmospheres, and in the
vicinity of detonation grounds, follow the instructions to switch off
electronic devices in order to prevent interference with detonation
and ignition systems.
