Restricting Children’s Access to Your Phone
Your phone is not a toy. Do not allow children to play with it
as they could hurt themselves and others, damage the
phone or make calls that increase your invoice.
USING YOUR PHONE WITH A HEARING
AID DEVICE
When some wireless phones are used with certain hearing
devices (including hearing aids and cochlear implants),
users may detect a noise which can interfere with the
effectiveness of the hearing device. Some hearing devices
are more immune than others to this interference noise,
and phones also vary in the amount of interference noise
they may generate. ANSI standard C63.19 was developed
to provide a standardized means of measuring both
wireless phone and hearing devices to determine usability
rating categories for both.
Ratings have been developed for mobile phones to assist
hearing device users find phones that may be compatible
with their hearing device. Not all phones have been rated
for compatibility with hearing devices. Phones that have
been rated have a label located on the box.
Your N818S
has an M4/T4 rating.
These ratings are not guarantees. Results will vary
depending on the user’s hearing device and individual type
and degree of hearing loss. If a hearing device is
particularly vulnerable to interference noise; even a phone
with a higher rating may still cause unacceptable noise
levels in the hearing device. 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 for hearing aid compatibility and are likely to
generate less interference to hearing devices than unrated
