Using the Elite Core HS - 10 is a breeze. First, pick the right boom arm and earpiece for your needs. If you're an adult, the medium or large earpiece should fit well; for kids or petite presenters, go for the small one. The standard boom is great for general use, while the short one is perfect for special cases like kids' theater. Decide how you want to wear the mic - on your ear, clipped, or as a wig mic. Once you've set it up, connect it to your wireless system using one of the two cables you've chosen. Remember to handle the earpieces and boom arms gently as they're detachable and delicate. After each use, store the HS - 10 in a dry place. Clean the earpieces regularly with a soft, dry cloth to keep them hygienic. Check the cables for any signs of damage before each use to ensure a seamless performance.
