Health and safety information
interference, you may not be able to use a rated
phone successfully. Trying out the
phone with your hearing device is the best way to
evaluate it for your personal
needs.
M-Ratings
: Phones rated M3 or M4 meet FCC
requirements and are likely to
generate less interference to hearing devices than
phones that are not labeled. M4 is
the better/higher of the two ratings.
T-Ratings
: Phones rated T3 or T4 meet FCC
requirements and are likely to be more usable with a
hearing device°Øs telecoil (°×T Switch°± or
°×Telephone Switch°±) than unrated phones. T4 is
the better/higher of the two ratings. (Note that not all
hearing devices have telecoils in them.)Hearing
devices may also be measured for immunity to this
type of interference. Your hearing device manufacturer
or hearing health professional may help you find
results for your hearing device. The more immune
your hearing aid is, the less likely you are to
experience interference noise from mobile phones.
Other Medical Devices
If you use any other personal medical devices, consult
the manufacturer of your device to determine if it is
adequately shielded from external RF energy. Your
physician may be able to assist you in obtaining this
information. Switch your phone off in health care
facilities when any regulations posted in these areas
instruct you to do so. Hospitals or health care facilities
may be using equipment that could be sensitive to
external RF energy.
Vehicles
RF signals may affect improperly installed or
inadequately shielded electronic systems in motor
vehicles. Check with the manufacturer or its
representative regarding your vehicle. You should also
consult the manufacturer of any equipment that has
been added to your vehicle.
