Using this LED lighted sign is a breeze. First, find a suitable location to mount it, like near the entrance of the service area. Then, use the provided mounting hardware to securely attach the sign to the wall. Connect the power supply using the 25 - foot extension cable. Once plugged in, the sign will light up and start conveying the message. As for maintenance, it's quite low - key. Since the LED lights last up to 50,000 hours, you don't have to worry about frequent bulb changes. Just clean the sign occasionally with a soft, dry cloth to keep it looking good. Avoid using harsh chemicals or abrasive materials that could damage the finish. And if you choose to use the additional flash module, make sure it's properly installed and functioning as expected.
