However, certain electronic equipment is not, therefore: • Do not use your mobile phone near medical equipment without requesting permission. Mobile phones may affect the operation of some implanted cardiac pacemakers and other medically implanted equipment. Pacemaker patients should be aware that the use of a mobile phone very close to a pacemaker might cause the device to malfunction. Avoid placing the mobile phone over the pacemaker, e.g. in your breast pocket. When using the mobile phone, place it at the ear opposite the pacemaker. If a minimum distance of 15 cm is kept between the mobile phone and the pacemaker, the risk of interference is limited. If you have any reason to suspect that interference is taking place, immediately turn off your mobile phone. Contact your cardiologist for more information. Some hearing aids might be disturbed by mobile phones. In the event of such disturbance, you may want to contact your local Call Centre to discuss alternatives. Aircraft • Turn off your mobile phone before boarding any aircraft. To prevent interference with communication systems, you must not use your mobile phone while the plane is in the air. • Do not use it on the ground without permission from the crew. Blasting Areas Turn off your mobile phone when in a blasting area or in areas posted "turn off two-way radio" to avoid interfering with blasting operations. Construction crews often use remote control RF devices to set off explosives. Explosive Atmospheres Turn off your mobile phone when in any area with a potentially explosive atmosphere. It is rare, but your mobile phone or its accessories could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. 132 Safe and Efficient Use
