To use the Sony MKS-8014 24-button auxiliary module, simply connect it to your CCP-8000 or CCP-6000 series control panel. It's easy to operate and will boost the functionality of your control system. When handling the module, be careful not to damage it. Since two button caps are missing, you might want to keep an eye on the buttons to avoid any issues. As for maintenance, keep it clean and dry. You can use a soft cloth to wipe it gently from time to time. If you have any further questions, refer to the photos provided or contact customer support.
