Using this Phaser3D Apex 40° mount for your DJI Action 2 is easy. First, make sure your DJI Action 2 is turned off. Then, gently attach the mount to your Impulse RC Apex or the relevant part of your equipment. You can insert an ND filter into the single ND filter slot to control the light when shooting. And if you have an acrylic screen protector, put it in the screen protector slot to keep your camera screen safe. When it comes to maintenance, use a soft, dry cloth to clean the mount regularly. Avoid using harsh chemicals as they may damage the TPU material. Also, store it in a cool and dry place when not in use. Be careful not to drop it or subject it to strong impacts, as this could affect its performance and shape.
