1.0 Important Safety Precautions
The LRAD-100X is capable of producing sound pressure levels (SPLs) that have the potential to
cause temporary or permanent hearing damage.
Always follow the safety precautions described in this manual as well as on the unit’s interfaces.
The following safety conventions appear throughout this manual. Please heed these warnings
and take the appropriate actions to ensure safe operation of the unit.
Important Safety Instructions
Risk of Electric Shock
Hearing Protection Required
Before operating the LRAD-100X, do the following:
1. Read these instructions.
2. Keep these instructions in a place known to and accessible by the potential operators
of the LRAD-100X.
3. Heed all warnings contained in this document.
4. Follow all instructions detailed in this document.
5. Install in accordance with the instructions contained in this document.
6. Do not expose yourself or others to high volume levels for prolonged periods of time.
7. Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatuses (including some electronics) that produce heat.
8. Only use attachments or accessories specified by the manufacturer.
9. Refer all servicing to qualified service personnel. Servicing is required when the LRAD-
100X has been noticeably or substantially damaged in any way, including cord or plug
damage, seriously dented or breached housings, or if liquid has penetrated the

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.

3.1 Charging the Battery
Prior to powering up the LRAD-100X, the battery must be fully charged. To charge the system
battery, perform the following steps:
1. Connect the battery’s male-end circular cable connector to its female counterpart on
the AC battery charger.
2. Plug the charger into an AC wall outlet. The charger can draw power from wall outlet
voltages rated between 100 and 240 VAC.
3. Allow the battery to charge until the indicator LED on the charger shows that charging is
complete. The LED will glow red when the battery is charging and will turn green when
the battery is fully charged.
3.2 Installing the Battery
Figure 2 – LRAD-100X Battery Compartment
1. Disconnect the battery from its charger.
2. Loosen the thumb screws on both battery retainers (item 1 in Figure 2) and rotate the
retainers so that the battery can be inserted into the base compartment.
3. Slide the battery into the base compartment.
4. Rotate the battery retainers so that the retainers hold the battery in its compartment
and tighten the thumbscrews.
5. Connect the battery cable connector to the rear power input connector on the bottom-
right of the LRAD-100X (item 2 in Figure 2).

3.3 Audio Connections
The handheld MP3 player contains the power and audio controls for the LRAD-100X.
To install the audio cable, connect the cable between the MP3 player’s top-right AUDIO OUT
connector and the matching audio in connector on the bottom-left of the LRAD-100X (see
Figure 3).
The audio cable can be wrapped around the LRAD-100X’s rear plate for ease of transportation.
Figure 3 – Audio Cable attached to MP3 Player
When it is necessary to broadcast live speech, connect the included microphone to the MP3
player. Install the microphone by connecting the microphone’s cable to the MIC/USB connector
located on the top-left of the MP3 player (see Figure 4 on the following page).

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.
