.Memory card instructions
• Insert the memory card (not included) into the dash cam immediately before use.
• The dash cam supports standard MicroSD cards. Use memory cards with a capacity of 16 GB ~ 128 GB and a speed class of 10 or higher.
• The default file system on the memory card may not be compatible with the dash cam. When inserting a memory card for the first time, format it in the dash cam before use. Formatting the memory card will erase all files on it. Back up important data in advance to another device.
• Multiple overwrite cycles may cause memory card damage, affecting its ability to store video and image files. In such cases, replace the memory card immediately.
• Use a high-quality memory card from a reputable manufacturer. Poor-quality cards may suffer from issues such as actual read/write speeds not matching the claimed specifications, or storage capacity being lower than advertised. The company is not responsible for lost or damaged video footage due to the use of low-quality memory cards.
• To prevent reduced read/write speeds after long-term use, it is recommended to format the dash cam’s memory card every two weeks.
• Do not insert or remove the memory card while the dash cam is powered on.

• If the battery deforms, swells, or leaks during use or storage, stop using the dash cam immediately to avoid safety issues and contact after-sales service.
