Using this Hitachi Z - 4000W camcorder is easy. First, connect it to an external power source if you have one as it doesn't come with a power supply. Then, turn it on and start recording your precious moments. When using the CX - Z3A triax adapter, make sure it's properly attached. As for the sticky plastic on the side of the camera, try to keep it clean. You can use a soft, dry cloth to wipe it gently. Avoid using harsh chemicals as they might damage the camera. Also, store the camcorder in a dry and cool place when not in use to maintain its performance.
