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
