1 Takingcare of your device Your device is a product of superior design & craftsmanship and should be handled with care: The following recommendations will help protect your phone: Keep the device dry. Precipitation, humidity, and all types of liquid or moisture may contain minerals that can rust electronic circuits. If your device gets wet, remove the battery and refrain from turning on device.Wipe it with a dry cloth and take it to the service center. Do not store the device under extreme temperatures; it can damage the 77 Do not use or store device in dusty and dirty areas; the electronic components may be damaged. Do not attempt to open device in any way other than instructed in this guide. Repairs attempted by an entity other than designated service agent/center will void warranty. Licking the battery or charger is strictly prohibited; saliva is more corrosive than water. Residual saliva may short-circuit phone and damage its motherboard, causing the device to become inoperable; battery & charger may also be damaged in the process. 1

WARNING: Licking USB plug or metallic battery component is strictly prohibited. Do not drop, knock, or shake device. Rough handling can disrupt internal circuit boards and fine mechanical parts. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the device. Use a soft and dry cloth to wipe down surfaces. Battery &charger safety Do not place battery in fire, explosion may occur.With concern for the environment, please abide local laws & ordinances in battery disposal. Only use original battery, charger, and accessories applicable to the specific mobile model. Failure to do so voids the warranty and may result in a hazard. Power off mobile prior to testing its charger. If charger malfunctions, off-mode will prevent damage to the motherboard. Please keep the charging mobile away from small children. Do not touch charger or mobile with wet hands; it’s hazardous and may damage electronic parts. WARNING: Risk of explosion if original battery is replaced. Tampering with mobile OS and ROOT voids warranty and may cause software instability. 2

15SAR declaration Specific Absorption Rate (SAR) Certification THIS DEVICE MEETS INTERNATIONAL GUIDELINES FOR EXPOSURE TO RADIO WAVES Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves (radio frequency electromagnetic fields) recommended by international guidelines. The guidelines were developed by an independent scientific organization (ICNIRP) and include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The radio wave exposure guidelines use a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit for mobile devices is 2.0 W/kg. Tests for SAR are conducted using standard operating positions with the device transmitting at its highest certified power level in all tested frequency bands. The highest SAR values under the ICNIRP guidelines for this device model are: Maximum SAR for this model and conditions under which it was recorded Head 0.588 W/Kg Body 0.451 W/Kg During use, the actual SAR values for this device are usually well below the values stated above. This is because, for purposes of system efficiency and to minimize interference on the network, the operating power of your mobile device is automatically decreased when full power is not needed for the call. The lower the power output of the device, the lower its SAR value. A body-worn SAR test has been performed on this device at a separation distance of 1.5cm.To meet RF exposure guidelines during body-worn operation, the device must be positioned at least 1.5cm away from the body. Organizations such as the World Health Organization and the US Food and Drug Administration have suggested that if people are concerned and want to reduce their exposure, they could use a hands-free accessory to keep the wireless device away from the head and body during use, or reduce the amount of time spent using the device. For more information, visit 17

www.tecno-mobile.comand search for your device with the model number. 16Restarting the phone If your phone is no longer responding, press and hold the power button for at least 10 seconds to reboot it. Note: Do not perform this operation if the phone is charging. Unplug the charger first. 18

17Warning Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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. changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. RF Exposure Information: The SAR limit of USA (FCC) is W/kg averaged over one gram of tissue. Device Types (FCC ID: 2ADYY-W4) has also been tested against this SAR limit.The highest SAR value reported under this standard during product certification for use when properly worn on the body is0.854 W/kg and for head is 0.526W /kg. Simultaneous RF exposure is 1.29 W/Kg. This device was tested for typical body‐worn operations with the back of the handset kept 10 mm from the body.To maintain compliance with FCC RF exposure requirements, use accessories that maintain amm separation distance between the user's body and the back of the handset. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided. NOTE: This equipment has been tested and found to comply with the limits for aClass B digital device, pursuant to Part 15 of the FCC Rules. These limits aredesigned to provide reasonable protection against harmful interference in aresidential installation. This equipment generates, uses and can radiate radiofrequency energy and, if not installed and used in accordance with the 19

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 isencouraged to try to correct the interference by one or more of the followingmeasures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit differentfrom that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. This device and its antenna(s) must not be co-located or operation in conjunction with any other antenna or transmitter. 20
