Precautions for users of implanted cardiac pacemakers Cardiac pacemakers (applies only to digital cordless telephones):

Wireless Technology Research, LLC

(WTR), an independent research entity, led a multidisciplinary evaluation of the interference between portable wireless telephones and implanted cardiac pacemakers. Supported by the U.S. Food and Drug Administration, WTR recommends to physicians that:

Pacemaker patients Should keep wireless telephones at least six inches from the pacemaker. Should NOT place wireless telephones directly over the pacemaker, such as in a breast pocket, when it is turned ON. Privacy: The same features that make a intercom system convenient create some limitations. Intercom calls are transmitted between the main unit and the sub unit(s) by radio waves, so there is a possibility that the intercom call conversations could be intercepted by radio receiving equipment within range of the intercom system. For this reason, you should not think of intercom call conversations as being as private as those on corded telephones. Electrical power: The main unit of this intercom system must be connected to a working electrical outlet. The electrical outlet should not be controlled by a wall switch. Calls cannot be made from the sub unit if the main unit is unplugged, switched off or if the electrical power is interrupted. Potential TV interference: Some intercom systems operate at frequencies that may cause interference to televisions and VCRs. To minimize or prevent such interference, do not place the main unit of the intercom system near or on top of a TV or VCR. If interference is experienced, moving the intercom system farther away from the TV or VCR often reduces or eliminates the interference. Rechargeable batteries: Exercise care in handling batteries in order not to create a short circuit with conducting material such as rings, bracelets and keys. The battery or conductor may overheat and cause harm. Observe proper polarity between the battery and the battery charger. Nickel-metal hydride rechargeable batteries: Dispose of these batteries in a safe manner. Do not burn or puncture the battery. Like other batteries of this type, if burned or punctured, they could release caustic material which could cause injury.

Stimulateurs cardiaques implants dans lorganisme Les simulateurs cardiaques (sapplique uniquement aux tlphones numriques sans fil) :

Lorganisme Wireless Technology Research, LLC (WTR), une firme de recherche indpendante, a men une valuation pluridisciplinaire des interfrences entre les tlphones sans fil portatifs et les stimulateurs cardiaques implants dans lorganisme. Appuye par lAdministration des aliments et drogues (FDA) des tats-Unis, la firme WTR recommande aux mdecins :

Avis aux dtenteurs de stimulateurs cardiaques Ils doivent tenir le tlphone sans fil une distance dau moins six pouces du stimulateur cardiaque. Ils ne doivent PAS placer le tlphone sans fil directement sur le stimulateur cardiaque, tel que dans une poche de chemise, lorsque celui-ci est en marche. Ils doivent utiliser le tlphone sans fil en lappuyant sur loreille qui se trouve dans la direction oppose au stimulateur cardiaque. Ltude effectue par lorganisme WRS na pas identifi de risque pour les dtenteurs de simulateurs cardiaques causs par les gens qui utilisent un tlphone sans fil proximit de ceux-ci. propos des tlphones sans fil Confidentialit : Les mmes caractristiques qui constituent des avantages pour les tlphones sans fil affichent galement des restrictions. Les appels tlphoniques sont transmis entre le combin sans fil et le socle par le biais dondes radio ; il y a donc la possibilit que vos conversations tlphoniques sans fil soient interceptes par des quipements de rception radio se trouvant dans la porte du combin sans fil. Pour cette raison, vous ne devez pas percevoir les communications tlphoniques sans fil comme tant aussi confidentielles que celles des tlphones cordons. Alimentation lectrique : Le socle de ce tlphone sans fil doit tre branch une prise lectrique fonctionnelle. La prise lectrique ne doit pas tre contrle par un interrupteur mural. Les appels ne pourront pas tre effectus du combin sans fil si le socle est dbranch ou mis hors tension ou si le courant est coup. Possibilit dinterfrences aux tlviseurs : Certains tlphones sans fil fonctionnent sur des frquences pouvant causer des interfrences aux tlviseurs et aux magntoscopes. Pour rduire ou prvenir de telles interfrences, ne placez pas le socle du tlphone sans fil prs ou sur un tlviseur ou magntoscope. Sil y a prsence de parasites, il est conseill dloigner le tlphone sans fil du tlviseur ou du magntoscope afin de rduire possiblement les interfrences. Piles rechargeables : Manipulez les piles avec soin afin de ne pas les court-circuiter avec des bagues, bracelets ou cls. Les piles ou le conducteur peut surchauffer et causer des blessures. Respectez la polarit adquate entre la pile et le chargeur. Les bloc-piles rechargeables lhydrure mtallique de nickel : Jetez ces blocs-piles de manire cologique et scuritaire. Ne les incinrez pas et ne les percez pas. Tel que les autres piles de ce type, elles pourraient dgager une matire toxique qui peut causer des blessures corporelles si elles sont brles ou perces.
