Turn on the HAC Setting When the HAC setting is on, your phone 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. It does not affect calls heard on the speakerphone or a headset. It’s better to turn off the Bluetooth function when the HAC setting is on. 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.

Confidential and Proprietary Information of ZTE CORPORATION 38C h a p t e r 17 Troubleshooting and FAQs If you encounter problems while using the phone, or if it performs erratically, you can consult the information in the chart below. If your particular problem cannot be resolved using the information in the chart, contact the dealer of handset. Problem Possible causes Possible solution Poor reception The network signal is too weak at your current location, for example, in a basement or near a tall building, because wireless transmissions cannot effectively reach it. Move to a location where the network signal can be properly received. The network is busy at the current time (for example, during peak times, there may be too much network traffic to handle additional calls). Avoid using the phone at such times, or try again after waiting a short time. You are too far away from a base station for your service provider. You can request a service area map from your service provider. Echo or noise Poor network trunk quality on the part of your service provider. Press the End Key and dial again. You may be switched to a better-quality network trunk or phone line. Poor local telephone line quality. Press the End Key and dial again. You may be switched to a better-quality network trunk or phone line. Unable to select certain features. Your service provider does not support these features, or you have not applied for services that provide these features. Contact your service provider. Battery will not charge. The battery or battery charger is damaged. Contact the dealer. The phone’s temperature is below 0℃ or higher than 45 ℃. Adjust the battery charging environment to avoid extremes of temperature. Poor contact between the battery and charger. Check all connectors to make sure all connections have been properly made. Shortened standby time The standby time is related to your service provider system configuration. The same phone used with different service providers’ systems will not provide exactly the same length of standby time. If you are located in an area where signaling is weak, temporarily switch off the phone. The battery is depleted. In high-temperature environments, battery life will be shortened. Use a new battery. If you are not able to connect to the network, the phone will continue to send out signals as it attempts to locate a base station. Doing so consumes battery power and will consequently shorten standby time. Change your location to one where the network is accessible, or temporarily turn off your phone. You cannot switch your phone on. Battery power has been depleted. Recharge the phone’s battery. (U)SIM card error (U)SIM card malfunction or damage. Take the (U)SIM card to your service

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. • This device 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: f Reorient or relocate the receiving antenna. f Increase the separation between the equipment and receiver. f Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. f Consult the dealer or an experienced radio/TV technician for help. f Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. • The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Radio Frequency (RF) Energy This device 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 U.S. Government. The exposure standard for wireless device employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. Tests for SAR are conducted using standard operating positions accepted by the FCC with the device transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the device is designed to operate at multiple power levels so as to use only the poser required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. The highest SAR value for the device as reported to the FCC when tested for head, as described in this user guide, is 1.00W/kg for UMTS band II. While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement.
