Using the Minolta MNCD350X car cam is easy. First, insert a MicroSD card (up to 32GB) into the slot. Then, power it on using the lithium-ion battery. Mount the cam in a suitable position in your car. You can start recording by pressing the record button. To review footage, use the 2.7-inch LCD screen. For night driving, the infrared LEDs will automatically turn on to provide clear vision. When it comes to loop recording, you can preset a file size or duration. Remember, the G-sensor will start recording in case of a collision. As for maintenance, keep the lens clean with a soft cloth. Avoid exposing the cam to extreme temperatures or humidity. If the battery runs out, you can recharge it using the Mini USB port. Also, regularly check the connections to ensure proper functioning.
