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 M6 or more would indicate excellent performance.
However, these are not guarantees that all users will be satisfied.
T-ratings work similarly.
M3 + M2 = M5
T3 + T2 = 5
The HAC rating and measurement procedure are described in the
American National Standards Institute (ANSI) C63.19 standard.

Device temperature
Caution! Some applications or prolonged usage may increase device
temperature.
Prolonged skin contact with a device that is hot to the
touch may produce skin discomfort or redness, or low temperature
burns. If the device feels hot to the touch, discontinue use and close
all applications or turn off the device until it cools.
Always ensure that the device has adequate ventilation and air flow.
Covering the device can significantly affect air flow, may affect the
performance of the device, and poses a possible risk of fire or explosion,
which could lead to serious bodily injuries or damage to property.
Covering the device can trap any dissipating heat and redirect it back to
the device while it is active. Although the device might not currently be
in full use, background applications and functions can generate heat that
can accidentally be trapped when covered.
