Safety and Warranty Information CQF2J40AQAAA TCL 30 Z SAR This device meets applicable national SAR limits of 1.6 W/kg. When carrying the device 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 using it. To prevent possible hearing damage, do not listen at high volume levels for long periods. Exercise caution when holding your device near your ear while the loudspeaker is in use. The device contains magnets which may interfere with other devices and items (such as credit card, pacemakers, defibrillators, etc.). Please maintain at least 150 mm of separation between your phone and the devices/items mentioned above. Table of contents Safety information ............................................................................................................1 General information .......................................................................................................10 1 YEAR LIMITED WARRANTY .......................................................................................12 1 Safety information .................................. 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. • TRAFFIC SAFETY Given that studies show that using a device 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 device when the vehicle is not parked. When driving, do not use your device or headphones to listen to music or to the radio. Using a headphone can be dangerous and forbidden in some areas. When switched on, your device emits electromagnetic waves that can interfere with the vehicle’s electronic systems such as ABS anti-lock brakes or airbags. To ensure that there is no problem: - do not place your device on top of the dashboard or within an airbag deployment area, - check with your car dealer or the car manufacturer to make sure that the dashboard is adequately shielded from device RF energy. • CONDITIONS OF USE You are advised to switch off the device from time to time to optimize its performance. Switch the device off before boarding an aircraft. Switch the device off when you are in healthcare facilities, except in designated areas. As with many other types of equipment now in regular use, these devices can interfere with other electrical or electronic devices, or equipment using radio frequencies. Switch the device off when you are near gas or flammable liquids. Strictly obey all signs and instructions posted in a fuel depot, petrol station, or chemical plant, or in any potentially explosive atmosphere. When the device is switched on, it should be kept at least 150 mm from any medical device such as a pacemaker, a hearing aid, or insulin pump, etc. In particular when using the device, you should hold it against the ear on the opposite side of the device, if applicable. To avoid hearing impairment, move the device away from your ear while using the hands-free mode because the amplified volume might cause hearing damage. 2 Do not let children use the device and/or play with the device and accessories without supervision. When replacing the cover, note that your device may contain 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 50°C(122°F). At over 50°C(122°F) the legibility of the device’s display may be impaired, though this is temporary and not serious. Emergency call numbers may not be reachable on all cellular networks. You should never rely only on your phone for emergency calls. Do not open, dismantle, or attempt to repair your device yourself. Do not drop, throw, or bend your device. To avoid any injury, do not use the device if the screen is damaged, cracked, or broken. Do not paint the device. Only use batteries, battery chargers, 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 chargers or batteries. Remember to make back-up copies or keep a written record of all important information stored in your device. 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 device regarding taking photographs and recording sounds with your device. Pursuant to such laws and regulations, it may be strictly forbidden to take photographs and/or record the voices of other people or any of their personal attributes, and duplicate 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 be obtained, if necessary, in order to record private or confidential conversations or take a photograph of another person. The manufacturer, the seller, vendor, and/or service provider of your device disclaim any liability which may result from the improper use of the device. • BATTERY Following air regulation, the battery of your product is not charged. Please charge it first. Observe the following precautions: - Do not attempt to open the battery (due to the risk of toxic fumes and burns); - Do not puncture, disassemble, or cause a short circuit in a battery; - Do not burn or dispose of a used battery in household rubbish or store it at temperatu…

Page 150 of 193 Picture D.3 Tilt position of the wireless device on the left side of SAM D.2 Body-worn device A typical example of a body-worn device is a mobile phone, wireless enabled PDA or other battery operated wireless device with the ability to transmit while mounted on a person’s body using a carry accessory approved by the wireless device manufacturer. Picture D.4Test positions for body-worn devices D.3 Desktop device A typical example of a desktop device is a wireless enabled desktop computer placed on a table or desk when used. The DUT shall be positioned at the distance and in the orientation to the phantom that corresponds to the intended use as specified by the manufacturer in the user instructions. For devices that employ an external antenna with variable positions, tests shall be performed for all antenna positions specified. Picture8.5 show positions for desktop device SAR tests. If the intended use is not specified, the device shall be tested directly against the flat phantom. No.I21Z62345-SEM03 ©Copyright. All rights reserved by CTTL.
