VI. Technical Specications
V. Considerations
1. 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.
2. 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 1-2 days.
3. The helmet contains the battery of 3.7V/450mAh. 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.
4. 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.
5. If the electronic functions do not work, please charge the helmet for 3 hours and then check if it works normally.
6. The helmet contains impact detection devices. Only if you connect your helmet with Smart4u APP, start
ride mode on the APP and your helmet suers from the heavy impact, SOS alert feature can be triggered. Your
emergency contacts set on Smart4u APP can accordingly receive your SOS messages.

To ensure signal stability for connection, please try not to place your mobile phone right against your body.
