The helmet contains electronic parts inside. Please do not take a long ride in the rain although the helmet can prevent the rain from splashing. �. After the helmet gets wet in the rain, the water droplets might occur in the chimney of tail LED lights. The water droplets will disappear when you put the helmet under the ventilation environment for �-� days. �. The helmet contains the battery of �.�V/����mAh. The battery capacity varies with temperature change. The battery life can decay when the helmet is used at low temperatures or below Zero degrees Celsius. �. Trying to clean the golden colour contacts of the charging plug sheet with metal or hard tools such as blades or tweezers is strictly forbidden. Please use cotton swabs with clean water or alcohol in case of cleaning. Please make sure the charging plug is clean and try while charging the helmet. �. If the electronic functions do not work, please charge the helmet for � hours and then check if it works normally. �. The built-in battery is forbidden to be disassembled, squeezed, heated or burned. It is also forbidden to use screwdrivers and other sharp devices breaking down or prying apart the battery. The above operations may make the battery caught fire. �. Please do not place the helmet with sharp objects, avoiding to damage the helmet. �. Replacement of a battery with an incorrect type that can defeat a safeguard (for example, in the case of some lithium battery types); �. Dsposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery that can result in an explosion; ��. Leaving a battery in an extremely high temperature surrounding environment that can result in an explosion or the leakage of flammable liquid or gas; and ��. Abattery subjected to extremely low air pressure that may result in an explosion or the leakage of flammable liquid or gas. Note: To maintain efficient battery life, it is recommended that the helmet be fully charged before any longterm storage (six months to one year). � Warning Warning �. How the helmet should be position on the head to ensure the intended protection is provided (e.g. that it should be placed so as to protect the forehead and not be pushed too far over the back of the head. �. That a helmet cannot always protect against injury. �. That a helmet subjected to a severe impact should be discarded and destroyed. �. A statement of the danger of modifying or removing any of the original component parts of the helmet other than as recommended by the manufacturer, and that helmets should not be adapted for the purpose of fitting accessories in a way not recommended by the manufacturer. �. This device complies with part �� of the FCC Rules. Operation is subject to the following two conditions:(�) This device may not cause harmful interfe- -rence, and (�) this device must accept any interference received, including interference that may cause undesired operation. Faults: �. Can not be charged or turn-off normally; �. The helmet is turn on, but the lights, micphone, speakers etc can not work normally; �. After power on, it turns off automatically in a short time. Note: Please refer to the quick guide of the specific model for function details. Warning � Instructions for Use and Care �.That the helmet can only protect if it fits well and that the buyer should try different sizes and choose the size which feels secure and comfortable on the head. �.That the helmet should be adjusted to fit the user e.g. the straps positioned so that they do not cover the ears, the buckle positioned away from the jawbone and the straps and buckle adjusted to be both comfortable and firm.
