INTRODUCTION
The Futurecom MOBEXCOM DVRS® Vehicular Repeater is designed to interface to a range of mobile radios
and control heads. It permits expanded operation of portable radios. The Vehicular Repeater system consists of.
a mobile radio, MOBEXCOM DVRS® Vehicular Repeater unit, a mobile radio Control Head and a RF
multiplexer. The Control Head communicates with the Vehicular Repeater and the mobile using a serial data
protocol.
REPEATER MODES
The Vehicular Repeater operates in one of three modes. The mode of operation is selectable from the Mobile
Control Head by the mobile radio operator.
The three modes are known as the MOBILE, LOCAL and SYSTEM modes. The function and purpose of each
mode is described as follows.
Mobile Mode
In the MOBILE mode, the vehicular repeater is completely disabled. The mobile radio is operational and
will permit the mobile radio user to communicate conventionally, using the mobile radio. The mobile user may
select the desired mobile operating channel, adjust the receiver volume level and transmit using the
microphone Push-to-Talk (PTT).
This mode is used when Repeater operation is not desired. The Vehicular Repeater System operates
similarly to a standard mobile radio system, as if the Repeater were not present. The RF multiplexer is
disabled and the antenna is connected directly to the mobile radio.
The MOBILE mode should be selected if several Repeater equipped vehicles are in the same area and
another Vehicular Repeater already has LOCAL or SYSTEM mode enabled.
Local Repeat Mode
In the LOCAL repeat mode, the Vehicular Repeater is enabled to permit communications among nearby
portable radio users and the mobile radio user. Repeater signals are not retransmitted by the Mobile Radio,
so that communications on the mobile channel will not be disturbed. However, all functions of the mobile
radio operate normally, except for scan, microphone mobile Push-to-Talk, scan activation, mode selection,
zone selection, home channel operation and mobile channel selection. When the LOCAL repeat mode is
selected, the mobile radio scan is deactivated and the mobile radio reverts to the selected mobile channel.
Signals received by the Vehicular Repeater receiver are heard in the mobile speaker and will also be
retransmitted by the Vehicular Repeater transmitter. Signals received by the Mobile receiver are heard in the
Mobile speaker and will be transmitted by the Vehicular Repeater. When signals are present in both the
Vehicular Repeater and Mobile receivers simultaneously, the signal from the Vehicular Repeater will have
priority in the mobile speaker. (Note that the receiver/PTT and speaker priorities are programmable.)
The mobile user will key only the Vehicular Repeater transmitter when using the microphone Push-toTalk. The Vehicular Repeater receiver has full priority over the mobile radio operator microphone Push-toTalk. To respond to a mobile signal, the mobile operator must enter either the MOBILE or SYSTEM mode to
be able to transmit from the mobile radio.
The mobile user may adjust the receiver volume level and transmit over the Vehicular Repeater using the
microphone Push-to-Talk.
The LOCAL mode, as the name implies, permits communications among portable radio users and the
mobile radio operator, without interfering with the mobile radio dispatch channels.
System Repeat Mode
In the SYSTEM repeat mode, both the Mobile Radio and the Vehicular Repeater are enabled to permit
the full exchange of communications among nearby portable radio users, the mobile radio user and the
dispatcher and other users on the Mobile Radio channel. Signals received by the Vehicular Repeater receiver
are heard in the mobile speaker and will also be retransmitted by both the Vehicular Repeater and Mobile
transmitters. Signals received by the Mobile receiver are heard in the mobile radio speaker and are also
retransmitted out of the Vehicular Repeater transmitter. However, all functions of the mobile radio operate
normally, except for scan, scan activation, mode selection, zone selection, home channel operation and
mobile channel selection. When the SYSTEM repeat mode is selected, the mobile radio scan is deactivated
and the mobile radio reverts to the selected mobile channel. When signals are present in both the Vehicular
Repeater and Mobile receivers simultaneously, the signal from the Vehicular Repeater will have priority in the
mobile speaker. (Note that the receiver/PTT and speaker priorities are programmable.)
Futurecom Systems Group Inc.DVRS Users Manual 8A083X01_UHF_Rev2_1 Rev. Preliminary

DVRS Vehicular Repeater System
The mobile user simultaneously keys both the Mobile radio and Vehicular Repeater transmitters when
using the microphone Push-to-Talk. The Vehicular Repeater receiver has full priority over the mobile radio
operator microphone Push-to-Talk. The mobile radio operator microphone Push-to-Talk has priority over the
Mobile receiver.
When signals are present in both the Vehicular Repeater and Mobile receivers simultaneously, the signal
from the Vehicular Repeater has priority in the mobile speaker.
The mobile user may adjust the receiver volume level and transmit over the Vehicular Repeater and
Mobile Radio, using the microphone Push-to-Talk.
The SYSTEM repeat mode is used when full communications among all radio parties is desired.
CONTROL HEAD
The control unit is a standard mobile radio control head. The Vehicular Repeater is designed to operate with a
variety of control heads. It is a ruggedly constructed weatherized control unit, incorporating an array of
pushbuttons, a Liquid Crystal display, 2 knobs and 2 LED indicators. The display and pushbuttons are backlit for
night time visibility.
The control unit is housed in a two-piece plastic, weather-resistant housing. The external radio/repeater
connections are made to connector on the rear of the unit. A microphone is provided and is secured to the control
unit connector on the front of the control unit.
A serial-control data interface is used to provide a communications connection between the control unit, the
Vehicular Repeater and the mobile radio.

red indicator lights whenever the mobile transmitter is keyed. The ‘Mobile Receiver Busy’ orange indicator lights
whenever the receiver is busy, regardless of presence or absence of any CTCSS (Channel-Guard) tone coding.
REPEATER RADIO UNIT
The Repeater is designed to implement a Vehicular Repeater System, to provide portable radio users greater
communication range by repeating signals through the vehicle's mobile radio to the dispatch centre. Various
modes of repeater operation are available, to suit different operational requirements. The Vehicular Repeater
Radio is the central connection point for the vehicular system. It connects to an external Control Head and Mobile
Radio.
It includes all the necessary hardware for repeater operations. The Repeater is housed in a weather resistant
metal enclosure with 2 removable covers. The covers provide protection for the connectors. The Repeater is
mounted on a RF multiplexer.
The Repeater communicates with the control head and the mobile radio via serial communication bus.
MOBILE RADIO UNIT

To Turn the Repeater ON or OFF
Press the button in the Volume knob located on the left side of the control unit. The display should
become active when the system turns ON. A test message appears briefly on the display. When the system
is turned ON, the Mobile Channel and Repeater Mode will automatically return to the same settings that were
in effect when the power was last turned OFF. Press the button in the Volume knob second time to turn the
Repeater OFF.
To Change the Speaker Volume
Turn the Volume knob until the desired volume level is reached.
To Change the Repeater Mode
Press the 'H/L' button once. The Repeater mode is changed in the following sequence: MOBILESYSTEM-LOCAL-… In the Mobile mode the alphanumeric display shows ‘ZONE CHANNEL’. In the System
mode the display changes to ‘RSYS CHANNEL’ and in the Local mode it shows ‘RLOC CHANNEL’. (‘ZONE’
is the selected Mobile zone name while ‘CHANNEL’ is the selected Mobile channel name.) When the LOCAL
or SYSTEM repeat modes are selected, the mobile radio scan is deactivated and the mobile radio reverts to
the selected mobile channel.
NOTE
The Mobile zone and channel cannot be changed while in LOCAL and SYSTEM
repeat modes.
Refer to the earlier description of repeat modes.
MOBILE XMIT Status Indicator
The 'MOBILE XMIT' red LED indicator is one of two status indicators that is provided on the Control
Head, located in the upper left corner. This indicator will light whenever the Mobile Transmitter is keyed. This
will occur in 'MOBILE' or 'SYSTEM' mode when the microphone Push-to-Talk is being pressed or when a
signal from the Vehicular Repeater is being retransmitted by the Mobile Radio (In 'SYSTEM' mode).
MOBILE BUSY Status Indicator
The 'MOBILE BUSY' orange LED indicator is one of two status indicators that are provided on the Control
Head, located in the upper left corner. This indicator will light whenever the Mobile Radio is receiving any
signal on the selected Mobile Channel. If CTCSS (Channel Guard) tone coding is used, the signal may not be
audible if the coding does not match.
Note that if the microphone is “off-hook”, the Mobile/Repeater audio will be heard on the speaker even if
CTCSS is not present or is incorrect. This is the same as the Monitor function.
ALPHANUMERIC Status Indication
The ‘ZONE’ is not displayed in the LOCAL and SYSTEM repeat modes. Instead, this portion of the
alphanumeric display shows the status of the Repeater in these two modes together with 'MOBILE XMIT' and
'MOBILE BUSY' status indicators.
