Using the Milwaukee 2319-20 M-Spector 4-Foot High-Resolution Inspection Camera is easy. First, insert the 4 AA batteries that come with the camera. Then, choose the right attachment - the plumbing ball for drain pipes or the mirror for other hard-to-see areas. Next, turn on the camera and adjust the brightness using the 5-mode setting according to the lighting conditions. You can use the 3 levels of zoom to focus on specific areas of interest. For a better view, use the digital 180° rotation. When you're done, turn off the camera and remove the batteries if you won't use it for a long time. Keep the camera in a dry place and clean the camera head gently with a soft cloth. Remember, the camera has a 5-year limited warranty, so if you have any problems, you can reach out for support.
