Preliminary Page 4 Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. WARNING: Changes or modifications not expressly approved by Futurecom Systems Group Inc. could void the user’s authority to operate the equipment. RF EXPOSURE WARNING: To Satisfy FCC/IC RF exposure requirements for mobile transmitting devices, a separation distance of 56cm or more should be maintained between the antenna of this device and persons during service operation. To ensure compliance, operations at closer than this distance is not allowed. The antenna for this transmitter must not be co-located in conjunction with any other antenna or transmitter. RADIO OPERATOR WARNING: Futurecom requires the MOBEXCOM Repeater operator to meet FCC Requirements for Radio Frequency Exposure. The minimum distance between all possible personnel and an omnidirectional antenna with gain not greater than 0dBd = 2.15 dBi must be at least 56cm (approximately 22”). Do not transmit with the MOBEXCOM repeater when persons are within the Maximum Permissible Exposure (MPE) distance of 56cm from the antenna, unless such persons (such as driver or Repeater operator) are shielded from antenna by a grounded metal barrier. The MPE distance is the minimum required distance between the antenna and a person to avoid RF exposure higher than the MPE level allowed by FCC. FAILURE TO OBSERVE THE MPE DISTANCE EXCLUSION AREA AROUND THE ANTENNA MAY ALLOW THOSE WITHIN THIS AREA TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE FCC SET MPE LIMIT. IT IS THE RESPONSIBILITY OF THE REPEATER OPERATOR TO ENSURE THAT MPE LIMITS ARE OBSERVED AT ALL TIMES DURING REPEATER TRANSMISSIONS. THE REPEATER OPERATOR MUST ENSURE AT ALL TIMES THAT NO PERSON COMES WITHIN MPE DISTANCE FROM THE ANTENNA. WARNING: The MOBEXCOM Repeater must be restricted to occupational use only to satisfy FCC RF exposure compliance.
Vehicular Repeater System Futurecom Systems Group Inc. 8A073X02_700.DOC Rev. Preliminary Page 5 ANTENNA INSTALLATION LOCATION IMPORTANT: The maximum allowed gain of the omnidirectional antenna for the MOBEXCOM Repeater is 0dBd (dipole) = 2.15 dBi.

Vehicular Repeater System Futurecom Systems Group Inc. 8A073X02_700.DOC Rev. Preliminary Page 6 2. INTRODUCTION The Futurecom MOBEXCOM® 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 e.g. a MCS2000 mobile radio, MOBEXCOM® 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-to-Talk. The Vehicular Repeater receiver has full priority over the mobile radio operator microphone Push-to-Talk. 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.)
Vehicular Repeater System Futurecom Systems Group Inc. 8A073X02_700.DOC Rev. Preliminary Page 7 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 e.g. the standard MCS2000 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 nighttimes 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. The following features are provided: Knobs for: ‘Volume’ with integral Power On/Off pushbutton switch ‘Channel’ selection Pushbuttons for: ‘Zone’ ‘Page’ ‘Monitor’ ON/OFF ‘Alarm’ (∆) ‘Private’ (∅) ‘Repeater mode’ selection (H/L) ‘Phon’ ‘Scan’ ‘Call’ ‘Opt’ ‘Home Menu’ ‘Sel’ LED Indicators for: ‘Mobile Transmit’ (Red LED) ‘Mobile Receiver Busy’ (Orange LED) Display: Alphanumeric LCD (with backlighting) Indicators are provided to display the receiver and transmitter status of the mobile. The ‘Mobile Transmit’ 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.
Vehicular Repeater System Futurecom Systems Group Inc. 8A073X02_700.DOC Rev. Preliminary Page 8 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. VHF MOBILE RADIO UNIT The Mobile Radio used in the Vehicular Repeater System is e.g. a standard Motorola MCS2000 radio. Refer to Motorola documentation for details of operation of this radio. The Vehicular Repeater is designed to operate with a variety of mobile radio units.

OPERATION CONTROL HEAD The Repeater Control Head selects mode of operation for both the Repeater and the Mobile Radio. 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: MOBILE-SYSTEM-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. The following tables summarize indicators for different Repeater states:
