Using the Lowell Unihorn LUH-15TA is a breeze. First, decide on the location where you want to install it. It can be installed indoors or outdoors, on different surfaces like brick or drywall. For the electrical connection, you can use the simple two - wire hook - up to the pigtail or through the waterproof gland - type cable fitting as described in the instruction sheet. Adjust the transformer using a screwdriver to the voltage that suits your needs (25V, 70V, or 100V), or use the 8 - ohm bypass input. When it comes to the grille, it's already press - fit and gives a nice, hardware - free look. Just make sure it's properly placed to protect the horn from birds and insects. For retrofit applications, you can easily replace the grille with an EIA standard grille for 8 - inch speakers. As for maintenance, keep an eye on the moisture - seal cover of the aluminum housing. Make sure it's intact to prevent water from getting inside. If the horn is in an area where it gets dirty often, gently clean the grille with a soft brush. Always refer to the instruction sheet if you have any doubts during installation, use, or maintenance.
