Using this FRAME panel kit is easy. First, take out the FRAME from the kit. Then, use the Allen wrench to install the 4 hexagon screws KA2x4 to attach the FRAME to your M5Core. Make sure the screws are tightened properly, but don't over - tighten them to avoid damaging the parts. When not in use, store the kit in a dry and clean place to prevent rusting of the screws. If the FRAME gets dirty, you can use a soft, dry cloth to gently wipe it clean. Avoid using harsh chemicals or abrasive materials as they may scratch the surface of the FRAME.
