Emergency Calls
This device, like any wireless mobile device, operates using radio signals, wireless and landline
networks, as well as user-programmed functions, which cannot guarantee connection in all
conditions, areas, or circumstances.
Therefore, you should never rely solely on any wireless mobile device for essential communications
(medical emergencies, for example). Before traveling in remote or underdeveloped areas, plan an
alternate method of contacting emergency services personnel. Remember, to make or receive any
calls, the mobile device must be switched on and in a service area with adequate signal strength.
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 cut off the call until given permission to do so.
To make an emergency call:
1. If the mobile device is not on, switch it on.
2. Open your phone dialer.
3. Enter the emergency number for your present location (for example, 911 or other official
emergency number), then tap Call/Send. Emergency 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. For example, if a hearing aid meets the M2 level rating and the wireless mobile device
meets the M3 level rating, the sum of the two values equals M5.
Under the standard, this should provide the hearing aid user with normal use while using the
hearing aid with the particular wireless mobile device. A sum of 6 or more would indicate excellent
performance.
However, these are not guarantees that all users will be satisfied. T ratings work similarly.
M3 + M2 = 5
T3 + T2 = 5
The HAC rating and measurement procedure are described in the American National Standards
Institute (ANSI) C63.19 standard.
HAC for Newer Technologies
This device has been tested and rated for use with hearing aids for some of the wireless technologies
that it uses. However, there may be some newer wireless technologies used in this device that have
not been tested yet for use with hearing aids.
It is important to try the different features of this device thoroughly and in different locations, using
your hearing aid or cochlear implant, to determine if you hear any interfering noise. Consult your
service provider or the manufacturer of this device for information on hearing aid compatibility. If you
have questions about return or exchange policies, consult your service provider or device retailer.
