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 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.
15
C90 User manual
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 1.6 W/kg averaged over one (1) gram of tissue. The
highest SAR value for this model phone tested for use at the head is 0.869 W/kg (1g)
The highest SAR value for this model phone tested for use at the body is 0.469 W/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
1.5 cm separation between the device, including its antenna, and the user’s body.
Emergency Services
To make an emergency call in any country:
1. Ensure your handset is ON and in service.
2. Press the End Key as many times as needed to clear the display and ready the device for
calls.
3. Enter a local emergency number, i.e., 911.
4. Press the Send Key to dial the number. Follow instructions received and do not end 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
16
C90 User manual
emergency calls cannot be guaranteed. You should never rely on any wireless device for
essential communication like medical emergencies.
FCC Notice

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.
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

C90 User manual
Use Your Phone with a Hearing Aid Device
Your C90 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 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 C90 has been tested for hearing aid device
compatibility and has an M4 and/or T4 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.
18
C90 User manual
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.
Turn on the HAC Setting
When the HAC setting is on, your C90 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.
