Using your Levy's wireless pack holder is easy. First, decide whether you want to attach it to your guitar strap or your belt. If using the guitar strap, use the hook - and - loop flap closure to secure it. Make sure the strap width doesn't exceed 2/51mm. For the belt, use the multiple belt loop slots with feed - thru adjustment, keeping in mind the max loop width of 1.5/38mm. Simply stretch the elastic web strap to place your wireless transmitter bodypack inside and it'll hold it firmly. You can also use the leather guitar pick slot on the outside to store your guitar picks. When it comes to maintenance, keep it away from excessive moisture and direct sunlight. If it gets dirty, you can gently wipe it with a soft, dry cloth. Avoid using harsh chemicals or cleaners. Also, don't overload the holder with items other than the wireless transmitter and a few guitar picks to ensure its long - term durability.
