Follow all instructions provided. Failure to do so may result in personal injury or damage to the device. The device comes with a 128G Micro SD card. Please format the Micro SD card before using it for the first time. To use a TF card, ensure that it is formatted with FAT32, has a storage capacity between 16GB and 256GB, and has a reading and writing speed no lower than U3. Please format the TF card before using it for the first time. Please regularly move your data from the Micro SD card to an external drive to avoid overloading the disk. We recommend reformatting the Micro SD card in this way at least once a month. Micro SD cards are subject to degradation over time due to repeated writing/erasing cycles. We recommend replacing the Micro SD Card every year to ensure that this degradation does not affect the performance of your dash cam. Do not insert or remove the TF card while the dash cam is actively recording, as this may damage the TF card. The NexiGo D621 can't protect drivers or passengers from automobile accidents.

The product can record and save footage of traffic accidents, but we do not guarantee all accident footage will be recorded and saved. Small collisions may not be detected by the sensor, and so the footage of the collision may not be stored with other event videos. Additionally, if the product is physically damaged during an accident, crash data may not be recorded. Ensure that you install the product correctly. Do not block the driver's vision. Do not obstruct the airbag. Keep the product at least 20 cm (7.8 in) away from the driver and passengers. Incorrect installation of the product may cause product failure and personal injury. Do not attempt to service the unit yourself. Opening the unit may expose you to dangerous voltages and other hazards. The unit should only be repaired by the manufacturer or its service agent. This device can only be used and powered as directed. Any unauthorized power distribution, such as plugging this item directly into the car battery, will void the warranty. For appliances having a specially prepared cord, if the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent. Only use attachments and accessories endorsed by the manufacturer. Keep this product away from strong magnetic fields to avoid damage. Do not use this product in temperatures higher than 70°C (158°F) or lower than -20°C (-4°F). Please note that the housing's temperature rises when the device is running. Do not handle the product roughly. Strong impact or shaking may cause irreparable damage to the product. Do not clean this product with harsh chemical solvents or cleaning fluids. 0203 PRODUCT INTRODUCTION The NexiGo D621 is a three-channel dash cam that uses G-sensor technology to detect and save footage in case of a collision or break-in. This footage can then be accessed wirelessly through the NexiGo Dash Cam app. This dash cam features three different cameras to capture vital footage from every angle. No matter the time of day, the interior wide-angle camera is adaptable to your space with its infrared LEDs and 180° vertical rotation. Meanwhile, the front and rear cameras capture 2K and 1080p quality footage with their advanced sensors.
