Vehicles Equipped With an Air Bag
An airbag inflates with great force. Do not place objects, including either installed or
portable wireless equipment, in the area over the airbag or in the airbag deployment area.
If in-vehicle wireless equipment is improperly installed and the airbag inflates, serious injury
could result.
Third Party Equipment
The use of third party equipment, cables or accessories, not made or authorized by ZTE,
may invalidate the warranty of the handset and also adversely affect the handset’s
operation. For example, use only the ZTE charger supplied with the handset.
Efficient Use
For optimum performance with minimum power consumption, do not cover the antenna
area (It’s on the bottom of your phone) with your hand. Covering the antenna affects the
call quality, may cause the handset to operate at higher power levels than needed, and
may shorten talk and standby times.
Radio Frequency (RF) Energy
Your handset is a low-power radio transmitter and receiver. When it is turned on, it
intermittently receives and transmits Radio Frequency (RF) energy in radio waves to
C78 User Manual
16
handle and control the power level at which the handset transmits. Exposure to radio
frequency energy:
Radio wave exposure and Specific Absorption Rate (SAR) information. The
handset is designed to comply with safely, requirements for exposure to radio
waves. This requirement is based on scientific guidelines that include safety
margins designed to assure the safety of all persons, regardless of age and
health.
The radio wave exposure guidelines employ a unit of measurement known as
the Specific Absorption Rate, or SAR. Tests for SAR are conducted using a
standardized method with the phone transmitting at its highest certified power
level in all used frequency bands.
While there may be differences between the SAR levels of various ZTE phone
models, they are all designed to meet the relevant guidelines for exposure to
radio waves.
The SAR limit recommended is 1.6w/kg averaged over one(1) gram of tissue.
The highest SAR value for this model phone tested for use at the head is
0.994w/kg(1g)
The highest SAR value for this model phone tested for use at the body is
0.679w/kg(1g) SAR compliance for body-worn operations is restricted to belt-
clips, holsters, or similar accessories that have no metallic component in the
assembly and which provide at least 1.5cm separation between the device,
including its antenna, and the users body.

the call until told to do so.
Note: Tell the operator which service you require: Police, Ambulance, Fire Engine,
Coastguard or Mountain Rescue Service. Give your position, and if possible, remain
stationary and maintain contact. Due to the nature of the cellular system, the connection of
emergency calls cannot be guaranteed. You should never rely on any wireless device for
essential communication like medical emergencies.
FCC Notice
This mobile phone 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.
C78 User Manual
18
This mobile phone 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 radiated 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.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
Use Your Phone With a Hearing Aid Device
Your C78 device is compliant with the FCC Hearing Aid Compatibility (HAC) requirements.
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
C78 User manual
19
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 C78 has been tested for hearing aid
device compatibility and has an M[4] and/or T[4] rating.
These ratings are not guarantees. 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. T-Ratings: Phones rated T3 or 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. T4 is the better/higher of the two ratings. (Note that not all hearing devices
contain telecoils.) The more immune your hearing aid device is, the less likely you are to
experience interference noise from your wireless phone. Hearing aid devices should have
ratings similar to those of phones. Ask your hearing health-care professional for the rating
of your hearing aid.
Hearing devices may also be measured for immunity to this type of interference. Your
hearing device manufacturer or hearing health professional may help you find results for
your hearing device. The more immune your hearing aid is, the less likely you are
to experience interference noise from wireless devices.
For additional information about the FCC's actions with regard to hearing aid compatible
wireless devices and other steps the FCC has taken to ensure that individuals with
disabilities have access to telecommunications services, please go to www.fcc.gov/cgb/dro.
C78 User Manual
20
Turn on the HAC Setting
When the HAC setting is on, your C78 sends the audio from your phone calls to the telecoil
rather than to the microphone of your hearing aid. You are likely to hear calls much better
because volume is increased and background noise and feedback are diminished. The
HAC setting improves only the calls you listen to through the earpiece. Turn off the
Bluetooth function. It does not affect calls heard on the speakerphone or with a headset.
HAC requires extra battery power, so watch your battery consumption when it's turned on.
CAUTION : Do not turn on the HAC setting unless you use a hearing aid with a telecoil.
Using this setting without a hearing aid or with a hearing aid without a telecoil may be
harmful to your hearing.
