Safety and Precautions CQF66L102AAA 1 Printed in China This product meets applicable national SAR limits of 1.6 W/kg. The specific maximum SAR values can be found in the Radio waves section. When carrying the product or using it while worn on your body, either use an approved accessory such as a holster or otherwise maintain a distance of 15 mm from the body to ensure compliance with RF exposure requirements. Note that the product may be transmitting even if you are not making a phone call. PROTECT YOUR HEARING To prevent possible hearing damage, do not listen at high volume levels for long periods. Exercise caution when holding your phone near your ear while the loudspeaker is in use. www.sar-tick.com 2 Safety and use ������������������������� We recommend that you read this chapter carefully before using your phone. The manufacturer disclaims any liability for damage, which may result as a consequence of improper use or use contrary to the instructions contained herein. TRAFFIC SAFETY: Given that studies show that using a phone while driving a vehicle constitutes a real risk, even when the hands-free kit is used (car kit, headset...), drivers are requested to refrain from using their phone when the vehicle is not parked. Check the laws and regulations on the use of wireless phones and their accessories in the areas where you drive. Always obey them. The use of these devices may be prohibited or restricted in certain areas. CONDITIONS OF USE: • You are advised to switch off the phone from time to time to optimize its performance; • Remember to abide by local authority rules of mobile phone use on aircrafts; • If your phone is a unibody device, where the back cover and battery are not removable, disassembling the phone will void your warranty. Disassembling the phone can cause bodily injury if the battery is punctured; • Always handle your phone with care and keep it in a clean and dust-free place; • Do not allow your phone to be exposed to adverse weather or environmental conditions, such as moisture, humidity, rain, infiltration of liquids, dust, sea air, etc. The manufacturer’s recommended operating temperature range is 0°C (32°F) to 55°C (131°F). At over 55°C (131°F), the legibility of the phone’s display may be temporarily impaired; • Do not open, dismantle, or attempt to repair your phone yourself; • Do not drop, throw, or bend your phone; • Use only batteries, battery chargers, and accessories which are recommended by TCL Communication Ltd. and its affiliates and are compatible with your phone model. TCL Communication Ltd. and its affiliates disclaim any liability for damage caused by the use of other chargers or batteries; • Your phone should not be disposed of in a municipal waste. Please check local regulations for disposal of electronic products; • Remember to make backup copies or keep a written record of all important information stored on your phone; • Some people may suffer epileptic seizures or blackouts when exposed to flashing lights, or when playing video games. These seizures or blackouts may occur even if a person never had a previous seizure or blackout. If you have experienced seizures or blackouts, or if you have a family history of such occurrences, please consult your doctor before playing video games on your phone or enabling a flashing-lights feature on your phone; • Parents should monitor their children’s use of video games or other features that incorporate flashing lights on the phones. All persons should discontinue use and consult a doctor if any of the following symptoms occur: convulsion, eye or muscle twitching, loss of awareness, orientation, or movements. 3 PRIVACY: Please note that you must respect the laws and regulations in force in your jurisdiction or other jurisdiction(s) where you will use your phone regarding taking photographs and recording sounds with your phone. Pursuant to such laws and regulations, it may be strictly forbidden to take photographs and/or to record the voices of other people or any of their personal attributes, and reproduce or distribute them, as this may be considered to be an invasion of privacy. It is the user's sole responsibility to ensure that prior authorization has been obtained, if necessary, in order to record private or confidential conversations or take a photograph of another person; the manufacturer, the seller or vendor of your phone (including the carrier) disclaim any liability which may result from improper use of the phone. BATTERY: Observe the following precautions: • Do not attempt to open the back cover; • Do not attempt to eject, replace, or open the battery; • Do not puncture the back cover of your phone; • Do not burn or dispose of your phone in household rubbish or store it at temperature above 60°C (140°F); Phone and battery as a unibody device must be disposed of in accordance with locally applicable environmental regulations. This symbol on your phone, the battery, and the accessories means that these products must be taken to collection points at the end of their life: • Municipal waste disposal centers with specific bins for these types of equipment; • Collection bins at points of sale. They will then be recycled, preventing substances being disposed of in the environment, so that their components can be reused. In European Union countries: These collection points are accessible free of charge. All products with this sign must be brought to these collection points. In non-European Union jurisdictions: Items of equipment with this symbol are not to be thrown into ordinary bins if your jurisdiction or your region has suitable recycling and collection facilities; instead they are to be taken to collection points for them to be recycled. In the United States you may learn more about CTIA’s Recycling Program at http://www.gowirelessgogreen.org/ CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS. CHARGERS: Home A.C./ Trav…
