III. PRECAUTIONS
1. Do not insert or remove the TF card while the device is operating, as this may cause
damage.
2. Pay attention to the insertion direction of the TF card. Inserting it in reverse may
damage both the device and the card.
3. After inserting a TF card, the device will set it as the default storage device; data on
the previously used card may become unreadable.
4. Supports up to 128GB. If the TF card is incompatible with the device, please reinsert
it or try another card.
5. If the device displays "Card Full" or "Card Error" and cannot record, check whether
the G-Sensor sensitivity is set to High. If the sensitivity is too high, bumps and shakes
during driving will cause files to be locked. Locked files cannot be overwritten by
loop recording; an accumulation of too many locked files will result in the memory
card being full and recording being unable to continue.
6. For first-time use of a new card, please format it on the device before use.
7. If a "Card Error" prompt appears or the device cannot read the card, try reinserting the
TF card and formatting it on the device. If the problem persists, try formatting the
card on a computer; if it cannot be formatted, the card is likely damaged.
