Using the ADJ Encore FR150Z is easy. First, connect the power using the powerCON In/Out ports. You can daisy - chain multiple fixtures together for more lighting coverage. Then, use the 4 - button LCD menu to set up your lighting preferences. To adjust the beam, use the manual control to change the angle between 8 and 50 degrees, and use the barn doors to control the beam dispersion. For dimming, use the controls to set it anywhere from 0 to 100%. When it comes to maintenance, keep the fixture clean by wiping it with a soft, dry cloth. Make sure to use the correct voltage (AC 100 - 240V, 50/60Hz) to avoid damaging the fixture. Also, handle the fixture carefully as it has a delicate lens and internal components. If you're not using it for a long time, store it in a dry and cool place.
