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 deplete your available minutes.
Using Your Phone With a Hearing Aid Device
Your LG Tribute has an M4/T4 rating.
While some wireless 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. The wireless telephone industry has developed a rating system for
wireless phones, to assist hearing device users to find 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 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 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 generate less
interference to hearing devices than phones that are not labeled. T4 is the better/higher of the
two ratings.
Hearing devices may also be rated. Your hearing device manufacturer or hearing health
professional may help you find this rating. Higher ratings mean that the hearing device is
relatively immune to interference noise. The hearing aid and wireless phone rating values are
then added together. A sum of 5 is considered acceptable for normal use. A sum of 6 is
considered for best use.
In the above example, if a hearing aid meets the M2 level rating and the wireless phone meets
the M3 level rating, the sum of the two values equal M5. This should provide the hearing aid
user with

―Normal usage‖ in this context is defined as a signal quality that’s acceptable for normal
operation.
The M mark is intended to be synonymous with the U mark. The T mark is intended to be
synonymous with the UT mark. The M and T marks are recommended by the Alliance for
Telecommunications Industries Solutions (ATIS). The U and UT marks are referenced in
Section 20.19 of the FCC Rules. The HAC rating and measurement procedure are described in
the American National Standards Institute (ANSI) C63.19 standard. To ensure that the Hearing
