Using this case is easy. First, finish assembling and testing your Geiger counter kit. Then, take the two cover plates provided and use the included screws and standoffs to attach them to the kit. Make sure the screws are tightened properly to ensure a secure fit. When it comes to maintenance, use a soft, dry cloth to clean the acrylic case. Avoid using harsh chemicals as they might damage the case. Remember, this case only protects your Geiger counter kit. You'll need to provide your own batteries and the counter kit itself.
