12 Calls
Cool down
In very limited circumstances, such as where your
phone has been exposed to extreme heat, “Cool
Down” message screens will appear. To avoid possible
damage to your battery and phone, you should follow
these instructions until the phone is within its
recommended temperature range. When your phone
is in “Cool Down” mode, only emergency calls can be
made.
Dual microphone noise cancellation
Dual microphone noise cancellation improves call
audio quality by removing the ambient noise around
you, and providing a cleaner, clearer sound to the
person you’re calling.
Note: Dual microphone noise cancellation is turned on
by default.
To turn off dual microphone noise cancellation, touch
> Settings> Call settings > Additional
call settings > Noise cancellation.
Features for the hearing impaired
Use your phone with a hearing aid
Note: Your phone has a hearing aid rating of M3.
For more information, see “Hearing Aid Compatibility
with Mobile Phones” on page 55.
For best results, use the optimization and phone
setting. They generally apply as well for users with
cochlear implants.
Optimize your phone position and orientation
While on a phone call slide your phone up and down,
then left and right until best microphone coupling is
obtained. You also may need to adjust your hearing aid
(HA) volume setting.
If your HA has a telecoil, activate its switch, then also
rotate the phone as illustrated to align the telecoils.
Note: Some automatically switched hearing aids may
need an auxiliary switching magnet.
