HEARING AID COMPATIBILITY
Note!
For hearing aid compatibility, you should turn off the Bluetooth connectivity.
Your mobile device model complies with FCC rules (C63.19-2011) governing hearing aid
compatibility. These rules require an M3 microphone or higher value. The M-value, shown
on the device box and below, refers to lower radio frequency (RF) emissions. A higher
M-value generally indicates that a device model has a lower RF emissions level, which may
improve the likelihood that the device will operate with certain hearing aids. Some hearing
aids are more resistant than others to interference. Please consult your hearing health
professional to determine the M rating of your hearing aid and whether your hearing aid will
work with this device.
Your device meets the M3/T4 level rating.
TTY COMPATIBILITY
Your mobile device model is compatible with TTY devices. Please check with the
manufacturer of your TTY device to ensure that it is compatible with digital cell phones.
For further information, please see the full manual.
