Using this sign is a breeze. First, find a suitable location for it, like in a law enforcement or security area. Then, use the included mounting hardware to install it on the wall. Connect the power supply and the 25 - foot extension cable. You can turn it on and off easily. If you want, you can add the optional flash module for extra attention. When it comes to maintenance, keep the sign clean by using a soft, dry cloth. Don't use harsh chemicals as they might damage the finish. The LEDs have a long lifespan of up to 50,000 hours, but if you notice any dimness or malfunction, it might be time to check the power supply or contact customer service. Also, make sure the installation area is dry to avoid any electrical issues.
