Using your Levy's wireless pack holder is easy. You can attach it to your guitar strap or belt. If using it on the guitar strap, open the hook-and-loop flap closure and secure it around the strap. For the belt, use the multiple belt loop slots and adjust the feed - thru as needed. When placing the wireless transmitter bodypack, stretch the elastic web strap and place the bodypack inside. Make sure it's snug. Remember, the holder fits most wireless transmitter models, but it's good to double - check before use. As for maintenance, keep it away from sharp objects to avoid tearing the leather and nylon. If it gets dirty, you can gently wipe it with a soft, dry cloth. Store it in a cool, dry place when not in use.
