2.0 System Description
The LRAD-100X is a self-contained, lightweight, and compact battery-powered hailer that
communicates with great intelligibility up to 600 meters.
Unlike handheld bullhorn devices, the LRAD-100X emits acoustic sound pressure levels up to
140 dB that result in clear, intelligible communications and unmistakable, stunning alert tones.
In addition to broadcasting alert tones, the LRAD-100X is also capable of playing prerecorded
messages and audio files stored in its MP3 player, and broadcasting live speech through its
handheld microphone.
The LRAD-100X’s rugged construction makes the device impact-resistant and completely
waterproof. Such construction allows the LRAD-100X to perform reliably in the harshest
conditions, whether on land or at sea.
The LRAD-100X’s rechargeable Lithium Iron Phosphate (LiFePO4) battery combines the power
density of a traditional lithium ion battery with a rugged design. Constructed with a cathode
material, this battery is far more resistant to thermal runaways than traditional lithium ion
batteries. This results in a high-powered battery that is safe to use in harsh environments.
The LRAD-100X is highly customizable. There are several different accessories and
configurations available, giving it the ability to function effectively in any environment.
The LRAD-100X is the smallest, most portable LRAD available, making it the ideal product for
law enforcement, emergency responders, and many other users.

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.

3.5 Using the Alert Tone
Press the ALERT TONE button (item 8 in Figure 6) to activate a pre-recorded alert sound. Press
once for activation, press again for deactivation. The pre-installed alert tone is an intense,
pulsating warning tone that is designed to be clearly heard at long distances.
It is recommended that the tone be used in 2-5 second bursts for maximum effectiveness when
hailing. Pressing the ALERT TONE button will interrupt playback of any other audio being
broadcast through the MP3 player.
Warning:
Avoid Exposure to Excessive Sound Levels.
The Alert Tone produces the loudest output from the LRAD-100X.
Qualified personnel must ensure the area in front of the LRAD-100X is
clear for 10 meters before activating the alert tone when the volume
control is in the RED zone of the PWR/VOL knob’s scale.
3.6 Aiming the LRAD-100X
The LRAD-100X is a highly directional audio device. The majority of the acoustic output power is
concentrated in a 30-degree cone in front of the device. This means that the sound directly in
front of the LRAD-100X is significantly louder than the sound behind and to the sides of the
device.
For optimal results, aim the device directly at the intended target.

4.0 Operation: Hailing and Warning
The LRAD-100X’s exceptional sound output and directionality can be used to hail, warn, and
notify clearly and intelligibly at distances up to 600 meters. Aim the LRAD-100X at your target
and broadcast sound from an audio file on the MP3 player, or speak directly to your target
using the handheld microphone. You can also attach an external audio device to the MP3 player
and use this device to playback and broadcast audio.
Warning:
Avoid Prolonged Exposure to Excessive Sound Levels.
Operator Hearing Protection is Required.
The LRAD-100X can produce acoustic sound pressure levels that OSHA
considers hazardous. As with any high-energy acoustic device, proper usage
of earplugs will minimize risk of hearing loss to the operator and personnel in
the immediate vicinity. Hearing protection is required when operating the
device at maximum volume from less than one meter away.
Warning:
Aim the LRAD-100X with Extreme Care.
Qualified LRAD-100X operators must ensure the device is positioned, aimed, and
operated in a manner that avoids exposing nearby personnel and bystanders to
excessive sound pressure levels. Follow these guidelines in conjunction with sound
judgment:
•Never operate the LRAD-100X at maximum volume when personnel are within
10 meters of the front of the device, or when the reflected distance between
personnel and an acoustically reflective object (i.e., a building, a wall, or a
bulkhead) is less than 10 meters.
•Never point LRAD-100X directly at personnel in the immediate vicinity of its
operating position.
•Note that the output power of the warning tone is slightly higher than the
output power of live broadcasts or other audio files.

4.1 LRAD-100X Operation Zones
Figure 5 – LRAD-100X Zones of Operation
•The LRAD-100X should have an unobstructed transmission path to its target. Even small
mast antennas may reflect some sound energy, thereby decreasing the LRAD-100X’s
effectiveness and increasing the reflected noise levels that will be felt by the operator
and others nearby.
•Avoid placing the LRAD-100X in a position where it will transmit sound over areas where
personnel may be located.
•For shipboard operation, place the LRAD-100X as close to the ship’s sides, bow, or stern
as possible.
Warning:
Hearing Protection Required
The LRAD-100X has very directional sound projection. Operators standing behind the
unit hear only a small fraction of the sound energy being transmitted. This can lead the
operator to falsely think that the LRAD-100X is not producing the required output.
OPERATORS SHOULD NOT ATTEMPT TO LISTEN TO THE OUTPUT FROM THE FRONT OF
THE DEVICE! HEARING DAMAGE MAY RESULT FROM SUCH ACTION.

14.0 Recording MP3, WAV or WMA Files
The LRAD-Normalizer software CD included with this kit is provided to optimize audio files for
use with the LRAD.
Recordings for playback on the LRAD can be created on any computer with a microphone. The
file formats that can be played back on the LRAD’s MP3 player include:
•MP3: MPEG Layer-3 compression, all bit rates, stereo or mono.
•WAV: Uncompressed PCM (Pulse Code Modulation), all bit rates, stereo or mono.
•WMA: Windows Media Audio compression, all bit rates, stereo or mono.
15.0 The Recording Microphone
The LRAD-100X system includes a rugged microphone with an integrated digital recording chip.
This microphone can record and store approximately one minute of audio and is also capable of
broadcasting live speech. To broadcast live speech, simply press and hold the PUSH TO TALK
(PTT) button (item 1 in Figure 10) and speak into the microphone.
In certain situations, the user may prefer to record a message instead of broadcasting live
speech. The recording feature is extremely useful when a message needs to be quickly recorded
for repeated continuous use, or when feedback cannot be avoided when broadcasting live
speech through the microphone.
15.1 Feedback
About microphone feedback:
Microphone feedback is caused when the microphone picks up the LRAD’s audio output,
causing a loud harmonic hum through the device. Placing the microphone directly in the sound
projection path of the LRAD and keying the PUSH TO TALK button will result in the worst-case
feedback scenario. This is because the sound being produced by the LRAD is being fed back into
itself, causing a reverberation and resulting in a loud screech from the device. When operating
the LRAD, the user should always be vigilant about limiting feedback.

LRAD-100X
GENASYS INC.
Manual Part No.: 106457-00 Rev E
16
How to Limit Feedback:
•Adjust the volume: Lower the LRAD’s volume until feedback is negated.
•Avoid reflections: If the output from the LRAD is bouncing off a solid object such as a
building and making its way back to the microphone, feedback will occur. Try
repositioning the LRAD or the microphone to prevent feedback.
•Maintain your distance: The farther away the microphone is from the LRAD, the less
feedback you will experience. Only use the microphone behind the LRAD, keeping it out
of the main acoustic beam.
•Shield the microphone: If possible, shield the microphone and the microphone operator
from the LRAD’s acoustic output to reduce feedback. Stand behind a physical barrier, or
inside a guard house or ship’s bridge. You may also use your free hand to cover the area
surrounding the microphone to attempt to limit feedback.
•Use the PUSH TO TALK button to your advantage: Releasing the PTT button on the
microphone immediately after speaking will limit feedback. Pressing and holding the
PTT button for longer than necessary may lead to feedback.
15.2 Recording Audio
When necessary, the microphone can be used to record, store, and playback a message of
approximately one minute in duration.
To record and playback audio with the microphone, reference Figure 10 on the following page
and perform these steps:
1. Press and hold the RECORD button (item 2 in Figure 10).
2. While holding the RECORD button, press and hold the PLAY button (item 3 in Figure 10).
3. The recording/playback indicator LED (item 4 in Figure 10) will light green to indicate that
the unit is recording.
•The unit will record as long as the RECORD and PLAY buttons are held down and as
long as there is available storage space in the internal memory.
4. Speak your message into the microphone element (item 5 in Figure 10) and release the
RECORD and PLAY buttons when done speaking.
5. Press and release the PLAY button to initiate playback of the recording. The
recording/playback indicator LED will flash once when the recording has finished playback.
6. Press and release the PLAY button again to halt playback of the recording.
