Using the Optrel Panoramaxx PAPR with e3000X System is easy. First, adjust the headband to get the best distance between the cassette and your eyes for optimal field of vision. Put on the helmet like you would a regular one. Once you start welding, the autopilot feature will automatically detect and set the right protection level for you, but you can switch it off and set the level manually if you prefer. To charge the battery, you can use solar cells or a USB cable. When it comes to maintenance, keep the helmet clean by gently wiping it with a soft cloth. Make sure to check the battery regularly and replace the filters as recommended by the manufacturer. Always store the helmet in a dry and cool place. And remember, if you have any problems, refer to the product's user manual or contact customer support.
