WARNING: Ensure the volume control is at the lowest setting before powering up the unit. The power supply to the LRAD-500X should be able to supply between 12 and 28VDC at 25 to 11 Amps. Ensure that the power supply is switched off prior to making or breaking the power connection to the LRAD-500X.
The MP3 player is preloaded with a number of warning and test messages that may be freely used as needed or deleted if not needed. The MP3 player output cord is connected to the back of the LRAD-500X through the MP3 INPUT port. Power is provided to the MP3 player from the LRAD-500X.
WARNING: The Tone Generator produces the loudest output from the LRAD-500X. Qualified personnel must ensure the area in front of the LRAD-500X is clear for 75 meters in front of the device before activating the tone at high volume levels.
• When choosing a placement area to maximize unobstructed transmission path(s), proper care must be taken to ensure the LRAD-500X does not collide with any structures or equipment nor encroach on personnel passageways when the unit is pivoted and manipulated through its full range of motion.
LRAD device. Do not spray the LRAD-500X front grille with pressurized liquid or air. Do not spray or otherwise introduce caustic solutions to the front grille. Doing so will increase the risk of damaging the emitters as well as other electronics contained within the unit.
