Emergency calls may not be possible on all wireless mobile device
networks or when certain network services and/or mobile device
features are in use. Check with local service providers. If certain features
are in use (call blocking, for example), you may first need to deactivate
those features before you can make an emergency call. Consult your
User Manual and your local cellular service provider. When making an
emergency call, remember to give all the necessary information as
accurately as possible. Remember that your mobile device may be the
only means of communication at the scene of an accident; do not end the
call until given permission to do so.
To make an emergency call:
1. If the mobile device is not on, turn it on.
2. Open the phone dialer.
3. Enter the emergency number for your current location (for example,
911 or other official emergency number), then tap Call/Send. Emer-
gency numbers vary by location.
FCC Hearing Aid Compatibility (HAC) regulations for wireless
devices
The U.S. Federal Communications Commission (FCC) has established
requirements for digital wireless mobile devices to be compatible with
hearing aids and other assistive hearing devices.
When individuals employing some assistive hearing devices (hearing
aids and cochlear implants) use wireless mobile devices, they may detect
a buzzing, humming, or whining noise. Some hearing devices are more
immune than others to this interference noise, and mobile devices also
vary in the amount of interference they generate.

The wireless telephone industry has developed a rating system for
wireless mobile devices to assist hearing device users find mobile
devices that may be compatible with their hearing devices. Not all mobile
devices have been rated. Mobile devices that are rated have the rating on
their box or a label located 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 mobile
device successfully. Trying out the mobile device with your hearing
device is the best way to evaluate it for your personal needs.
M-Ratings:
Wireless mobile devices rated M3 or M4 meet FCC
requirements and are likely to generate less interference to hearing
devices than mobile devices that are not labeled. M4 is the better/higher
of the two ratings. M-ratings refer to enabling acoustic coupling with
hearing aids that do not operate in telecoil mode.
T-Ratings:
Mobile devices rated T3 or T4 meet FCC requirements and
are likely to generate less interference to hearing devices than mobile
devices that are not labeled. T4 is the better/higher of the two ratings.
T-ratings refer to enabling inductive coupling with hearing aids operating
in telecoil mode.
Hearing devices may also be rated. Your hearing aid manufacturer or
hearing health professional may help you find this rating. Higher ratings
mean that the hearing device is relatively immune to interference noise.
Under the current industry standard, American National Standards
Institute (ANSI) C63.19, the hearing aid and wireless mobile device rating
values are added together to indicate how usable they are together.
