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 handsets 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 (Its 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 15 C78 User Manual 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.

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. 17 C78 User Manual 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 users 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 18 C78 User manual 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 devices 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. 19 C78 User Manual 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.
