Getting the Best Hearing Device Experience
With Your Phone
To further minimize interference:
+ Set the phone’s display and keypad backlight
settings to ensure the minimum time interval:
1. Tap > > Settings > Display > Sleep.
2. Select 15 seconds to set the minimum time
interval setting.
+ Position the phone so the internal antenna is
farthest from your hearing aid.
+ Move the phone around to find the point with
least interference.
Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most
out of your battery’s performance.
+ Recently there have been some public reports
of wireless phone batteries overheating,
catching fire, or exploding. It appears that many,
if not all, of these reports involve counterfeit
or inexpensive, aftermarket-brand batteries
with unknown or questionable manufacturing
standards. Boost is not aware of similar
problems with Boost phones resulting from
the proper use of batteries and accessories
approved by Boost or the manufacturer
of your phone. Use only Boost-approved
or manufacturer-approved batteries and
accessories found at boostmobile.com or
through your phone’s manufacturer. Buying the
right batteries and accessories is the best way
to ensure they’re genuine and safe.
+ In order to avoid damage, charge the battery
only in temperatures that range from 32° F to
104° F (0° C to 40° C).
+ Don’t use the battery charger in direct sunlight
or in high humidity areas, such as the bathroom.
are likely to generate less interference to hearing
devices than unrated phones.
T-Ratings: Phones rated T4 meet FCC
requirements and are likely to be more usable
with a hearing device’s telecoil (“T Switch” or
“Telephone Switch”) than unrated phones.
Note: New Technologies, Including Wi-Fi
This phone has been tested and rated for
use with hearing aids for some of the wireless
technologies that it uses. However, there may be
newer wireless technologies (including Wi-Fi)
used in this phone that have not been tested for
use with hearing aids.
Hearing aid devices may also be measured for
immunity to interference noise from wireless
phones and should have ratings similar to phones.
Ask your hearing healthcare professional for
the rating of your hearing aid. Add the rating of
your hearing aid and your phone to determine
probable usability:
+ Any combined rating equal to or greater than six
offers excellent use.
+ Any combined rating equal to five is considered
normal use.
+ Any combined rating equal to four is
considered usable.
Thus, if you pair an M3 hearing aid with an M3
phone, you will have a combined rating of six for
“excellent use.” This is synonymous for T ratings.
It is further suggested you experiment with
multiple phones (even those not labeled M3/T3
or M4/T4) while in the store to find the one that
works best with your hearing aid device. Should
you experience interference or find the quality
of service unsatisfactory after purchasing your
phone, promptly return it to the store.
