Persons with pacemakers:
• should always keep the phone more than 15 cm
(6 inches) from their pacemaker when the phone
is switched on.
• should not carry the phone in a breast pocket.
• should use the ear opposite the pacemaker to
minimize potential interference.
If you have any reason to suspect that interference is
taking place, switch your phone off immediately.
Hearing Aid Compatibility with Mobile
Phones
When some mobile phones are used near some
hearing devices (hearing aids and cochlear
implants), users may detect a buzzing, humming, or
whining noise. Some hearing devices are more
immune than others to this interference noise, and
phones also vary in the amount of interference they
generate.
24
The wireless telephone industry has developed
ratings for some of their mobile phones, to assist
hearing device users in finding phones that may be
compatible with their hearing devices. Not all phones
have been rated. Phones that are rated have the
rating on their box or a label on the box.
The ratings are not guarantees. Results will vary
depending on the user's hearing device and hearing
loss. If your hearing device happens to be vulnerable
to 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.
