INTRODUCTION / INTENDED USE The AX3 LightDrop BTB from ASTERA is a LED spotlight for professional use in the event and film business. The AX3 LightDrop BTB is designed for direct or indirect illumination of objects or sceneries. Due to its built-in battery it can be quickly set up at places where traditional lights cannot be mounted easily. It can be used as compact uplight as well as hanging or standing spotlight and inside translucent objects, truss, etc. The AX3 LightDrop BTB generates white or colored light and the color tempe- rature can be adjusted in many ways. The AX3 LightDrop BTB can be controlled with the AsteraApp or wireless CRMX. The device can also be controlled by the integrated button or by infrared remote control. Thanks to its built-in Bluetooth it can be used as BluetoothBridge (BTB). The AX3 LightDrop BTB can be used standing or hanging. For this purpo- se, the device is equiped with a magnet, a bracket and 3 M4 threads. Its removable bracket has a 3/8“ thread to attach the appropriate mounting accessories. The AX3 LightDrop BTB can be used indoors and outdoors and has an IP65 rating (only with the Charging Socket Cover (AX3-SP) in place). Do not shake the device. Avoid brute force when installing or operating the device. When choosing the installation spot, please make sure that the device is not exposed to extreme heat or dust. Avoid direct sunlight for a longer period of time. The specified ambient temperature must be maintained. Keep away from direct insulation (particularly in cars) and heaters. Never use the device during thunderstorms connected to the power mains. Overvoltage could destroy the device. Always disconnect the device during thunderstorms. Make sure that the area below the installation place is blocked when rigging, derigging or servicing the fixture. Always fix the fixture with an appropriate safety wire.
