3.4 Playing Audio Files
To broadcast audio files using the LRAD-100X, perform the following steps:
1.
Power on the LRAD-100X by turning the MP3 player’s PWR/VOL knob (item 2 in Figure
6) clockwise from the OFF position. The PWR/VOL knob will click on and the unit will
power up.
2.
Select the desired audio file by cycling through the files on the MP3 player. Use the SKIP
FORWARD and SKIP REVERSE buttons (items 6 and 7 in Figure 6) to cycle files.
Warning:
Avoid Exposure to Excessive Sound Levels.
Always initiate audio playback with the volume on
a low setting.
3.
Press the PLAY/PAUSE button (item 4 in Figure 6) to start playing an audio file from the
MP3 player, slowly adjusting the PWR/VOL knob until the desired volume is reached.
NOTE:
The LRAD-100X’s on-board power converter features capacitive filtering on its input to
minimize noise levels. These capacitors will require 3 to 5 seconds to fully discharge after
powering off the LRAD. Cycling the power on and off repeatedly within less than one second
will result in a popping sound from the LRAD-100X. To prevent this popping sound, allow at
least 5 seconds to pass before turning the unit back on.
