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. IV. SYSTEM ERROR MESSAGE DEFINITIONS Error Message Description Solution No Card Inserted No TF card detected, recording unavailable Insert a TF card No File No card inserted / No recording yet Insert card and record or take photos Card Error / Please Format Incorrect card format Go to menu to format the card SENSOR FAIL Sensor initialization error, cannot record If it persists, please contact the dealer for repair SD Card Full Insufficient space when taking a photo, displayed during photo capture Delete or unlock some files to free up space V.
