1. No memory card, support up to 256GB (Class 10), but Samsung Evo 64GB (class 10) card is recommended. We recommend to format your card every two weeks.
2. Please charge for 2 hours at the first time to prolong the battery life.
3. Please keep the Dash Cam connected to a power source at all times during operation, or the dash cam won't stay on for more than 30 senonds, as the built in 250mAh battery is just to keep setting.
4. There are two versions of the video files at each time, one is the lower resolution to fit the cellphone, the other one is the higher resolution for watching it on camera or the computer.
