Using Your Phone With a
Hearing Aid Device
Your Z750C is compliant with the FCC Hearing Aid
Compatibility (HAC) requirements. For additional HAC
information, including the HAC rating of this product,
please refer to www.zteusa-support.com.
When 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 ratings for
some of their mobile phones to assist hearing device
users in finding phones that may be compatible with
their hearing devices. Not all phones have been rated.
Phones that have been rated have a label on the box.
Your Z750C has been tested for hearing aid
device compatibility and has an M4 /T4 rating.
These ratings are not guaranteed. Results will vary,
depending on the level of immunity of your hearing
device and the degree of your 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
with hearing devices than phones that are not labeled.
M4 is the better/higher of the two ratings.

FCC Compliance
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired
operation.
CAUTION: Changes or modifications not expressly
approved by the manufacturer could void the user’s
authority to operate the equipment.
NOTE: This equipment has been tested and found
to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable
protection against harmful interference in a residential
installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause
harmful interference to radio communications. However,
there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause
harmful interference to radio or television reception, which
can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV
technician for help.
For Your Safety
Radio Frequency (RF) Energy
This model phone meets the government’s requirements
for exposure to radio waves.
This phone is designed and manufactured not to exceed
the emission limits for exposure to radio frequency (RF)
energy set by the Federal Communications Commission
of the United States, Industry Canada of Canada.
During SAR testing, this device is set to transmit at its
highest certified power level in all tested frequency
bands, and placed in positions that simulate RF
exposure in usage against the head with no separation,
and near the body with the separation of 0.4 inches
(10 mm). Although the SAR is determined at the highest
certified power level, the actual SAR level of the device
while operating can be well below the maximum value.
This is because the phone is designed to operate at
multiple power levels so as to use only the power
required to reach the network. In general, the closer you
are to a wireless base station antenna, the lower the
power output.
The exposure standard for wireless devices employs a
unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg,
and 1.6 W/kg by Industry Canada.
This device is compliance with SAR for general
population/ uncontrolled exposure limits in ANSI/IEEE
C95.1-1992 and Canada RSS 102, and had been tested
in accordance with the measurement methods and
procedures specified in OET Bulletin 65 Supplement C,
and Canada RSS 102. This device has been tested, and
meets the FCC, IC RF exposure guidelines when tested
with the device directly contacted to the body.
For Your Safety
The FCC has granted an Equipment Authorization for
this model phone with all reported SAR levels evaluated
as in compliance with the FCC RF exposure guidelines.
SAR information on this model phone is on file with the
FCC and can be found under the Display Grant section
of www.fcc.gov/oet/ea/fccid after searching on FCC
ID: Q78-Z750C.
For this device, the highest reported SAR value for
usage against the head is 1.27 W/kg, for usage near
near the body is 1.30 W/kg.
While there may be differences between the SAR levels
of individual Z750C phones and at various positions,
they all meet the government requirement.
SAR compliance for body-worn operation is based on
a separation distance of 0.4 inches (10 mm) between
the unit and the human body. Carry this device at least
0.4 inches (10 mm) away from your body to ensure RF
exposure level compliant or lower to the reported level.
To support body-worn operation, choose the belt clips
or holsters, which do not contain metallic components,
to maintain a separation of 0.4 inches (10 mm)
between this device and your body.
RF exposure compliance with any body-worn accessory,
which contains metal, was not tested and certified, and
using such body-worn accessory should be avoided.
