Safety and warranty information HH42NK1 CQF1YN2LCAAA Safety and use We recommend that you read this chapter carefully before using your device. The manufacturer disclaims any liability for damage, which may result as a consequence of improper use or use contrary to the instructions contained herein. • CONDITIONS OF USE: Switch the device off before boarding an aircraft. Switch the device off when you are in health care facilities, except in designated areas. As with many other types of equipment now in regular use, devices can interfere with other electrical or electronic devices, or equipment using radio frequency. Switch the device off when you are near gas or flammable liquids. Strictly obey all signs and instructions posted in a fuel depot, gas station, chemical plant, or in any potentially explosive atmosphere. When the device is switched on, it should be kept at least 20 cm from the body and at least 15 cm from any medical device such as a pacemaker, a hearing aid, or an insulin pump, etc.. Do not let children use the device and/or play with the device and accessories without supervision. If your device has a removable cover, note that your device may contain substances that could create an allergic reaction. If your device is a unibody device, the back cover is not removable. If you disassemble your device the warranty will not apply. Disassembling the device may cause leakage of substances that could create an allergic reaction. Always handle your device with care and keep it in a clean and dust-free place. Do not allow your device to be exposed to adverse weather or environmental conditions (moisture, humidity, rain, infiltration of liquids, dust, sea air, etc.). The manufacturer’s recommended operating temperature range is 0°C (32°F) to +45°C (113°F). Do not open, dismantle, or attempt to repair your device yourself. Do not drop, throw, or bend your device. Do not paint it. Use only adapters and accessories which are recommended by TCL Communication Ltd. and its affiliates and are compatible with your device model. TCL Communication Ltd. and its affiliates disclaim any liability for damage caused by the use of other adapters. This symbol on your device, 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 items of equipment; - Collection bins at points of sale. They will then be recycled, preventing substances from 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. • Adapters: Main power adapters will operate within the temperature range of: 0°C (32°F) to 40°C (104°F). The adapters designed for your device meet the standard for safety of information technology equipment and office equipment use. Due to different applicable electrical specifications, an adapter you purchased in one jurisdiction may not work in another jurisdiction. They should be used for this purpose only. Radio waves THIS DEVICE MEETS INTERNATIONAL GUIDELINES FOR EXPOSURE TO RADIO WAVES. Your 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 ensure the safety of all persons, regardless of age and health. Your device is equipped with a built-in antenna. For optimal operation, you should avoid touching it or degrading it. 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. L’antenne (s ) utilisée pour ce transmetteur doit être installé pour fournir une distance de séparation d’au moins 20 cm de toute personne. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons. • FCC Caution: Changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment. • FCC Statement: This equipment 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: –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.
