Introduction
This is the user guide for the WatchGuard Video Long Range Transmitter
(LRT) Wireless Microphone. The LRT Microphone is a specialized
device designed to be used exclusively with WatchGuard’s family of
vehicle-based digital video recorder (DVR) products. This Guide’s
purpose is to describe the proper connection, installation and use of the
LRT Microphone.
General Operation
The LRT connects directly to all WatchGuard DVR products to supply
one of the audio tracks during the video recording process. The LRT
microphone is a system with two primary devices; the Transmitter and the
Base. Typically, the user (for example, a police officer) will wear the
Transmitter device on their body. This device can be attached to the user
with one of the available spring-loaded clips or worn in a holster on the
user’s belt. Like the DVR, the LRT Base device mounts in a vehicle using
one of several brackets and attaches to the DVR using a cable. The Base
device also requires an antenna connection to provide the wireless radio
link to the Transmitter device. This antenna is supplied as part of the LRT
microphone system and mounts to the vehicle windshield using an
adhesive.

Installation
Important: Please turn off the power to the digital video system before
connecting or disconnecting any microphone system cables.
Please reference Figure 1 during the installation process. Reference the
WatchGuard Video “Microphone Installation Instructions – document
number WGD00011” for further details.
Mounting the Base
Select an appropriate location inside the vehicle to mount the Base
mounting bracket. Attach the bracket to the vehicle using the supplied
mounting hardware then slide the Base onto the bracket so it locks into the
Base mounting bracket slot.
Antenna Connection
The supplied Base antenna is intended to be mounted on the interior of the
vehicle in the upper right corner of the windshield. This long, thin
antenna should be mounted horizontally for best performance.
Remove the backing from the adhesive strip on the supplied window
mount antenna. Press the exposed adhesive side of the antenna onto the
selected windshield location.
Connect the antenna cable to the Base at the point indicated in Figure 1.
Warning: The RP-SMA connector should be finger tightened only. No
hand tools should be used when making the antenna connection.
Only 900MHz antennas available from WatchGuard Video should be
used. Wireless performance and audio quality will be affected if a non-
approved antenna is used.
DVR Cable Connection
Connect the supplied digital video recording (DVR) system interface cable
to this point. This cable supplies power from the DVR to the Base device
when the DVR power is turned on. This cable also transfers the audio
signal from the microphone system to the DVR for inclusion in the DVR
video recording.

Base Unit Features
Red and Green Status LEDs
Please reference Figure 2.
The green LED on the Base will light when communicating with the
Transmitter device. The LED will light solid green when a voice recording
is enabled. During a voice recording, this LED will flash when the
Transmitter is muted. When a recording is not active, this LED will flash
when the Base is attempting to associate (bind) with a Transmitter device.
The red LED on the Base will light when the transmitter is inserted into
the base. The LED will light red when the battery is charging. The green
LED will light when the battery is fully charged.

Binding a Base with a Transmitter
To function correctly, a specific Transmitter device must be bound or
associated with a specific Base. This is the process that allows the Base
and Transmitter to communicate wirelessly without interfering with other
Base/Transmitter pairs.
To bind a Transmitter to a Base, ensure the Base device is properly
installed in a vehicle as describe above. Power-on the DVR to apply
power to the Base. Insert the Transmitter device into the Base cradle fully

until the contacts on the bottom of the Transmitter (Figure 5) connect with
the contacts on the Base (Figure 3).
The Base and Transmitter LEDs will flash briefly. After a few seconds,
the binding process is complete. The Base and Transmitter are now ready
for normal use.

SYSTEM CONTROLS AND FEATURES
Transmitter Unit Features
Transmitter Power On/Off
Refer to Figure 5. Use this switch to turn the Transmitter device power on
and off. This switch must be in the ON position for all Transmitter-
recording functions to operate properly.
Figure 5: Transmitter Bottom
Talk/Mute Slide Switch
Refer to Figure 6. This control is used to enable microphone voice
recording and to mute the audio during a recording. When the Transmitter
power is turned on and the transmitter is bound with the Base, slide this
control down to begin voice recording. Once activated, the green
Transmitter LED will light and remain solid. Pressing the button again
will stop the recording function if the DVR is configured for this behavior.
The green Transmitter LED will turn off.
Behavior of the slide switch function can be overridden by the video
system (DVR). Settings on the DVR system can, for example, force the
recording function to remain on even though the Transmitter slide switch
is pressed. See the DVR system user manual for complete details.
Mute
With Transmitter voice recording enabled, the slide switch can be pressed
and held to suppress detection of the voice by both the internal and
externally connected (lapel) microphones. Once this switch is help down,
the green Transmitter LED will flash. The Transmitter will continue to
