Using this sign is a breeze. First, find a good spot outside the exam room door where it can be easily seen. Then, use the included mounting hardware to attach the sign to the wall. Connect the power supply using the 25 - foot extension cable. You can turn the sign on and off as needed. If you want a flashing effect, you can add the optional flash module. As for maintenance, keep the sign clean by gently wiping it with a soft, dry cloth. Avoid using harsh chemicals. The LED lights are long - lasting, up to 50,000 hours, but if you notice any issues, check the power connection first. Store the sign in a dry place when not in use to prevent damage.
