STP8000 Series CAR KIT INSTALLATION & USER GUIDE 1 sepura INTRODUCTION The STP8000 car kit provides secure retention of the radio within a cradle. The car kit features battery charging, external antenna connection, external PTT keypad, hands-free operation with the external microphone and loudspeaker. A standard RS232 data port and USB is provided for data transfer applications. Connections are provided for optional accessories. Cable colour Electrical parameters Fuse RED Vehicle +ve (12v MAX) 4 Amp BLACK Vehicle –ve (vehicle chassis) n/a PINK Open drain Output, max current 0.5A Protected by a re-settable fuse provided inside car kit YELLOW Open drain Output, max current 0.5A Protected by a re-settable fuse provided inside car kit BLUE Input Signal Level 12VDC (200 uA max) 1 Amp sepura or MICSMICALARMPTT REMOTE PTT CRADLE Front INTERFACE UNIT (user interface) USBDATA (RS232)SXC HANDSET/FIST MIC Loudspeaker Output 50Ω Rear INTERFACE UNIT (vehicle harness) Antenna Connections for accessories STP8000 Series CAR KIT INSTALLATION & USER GUIDE 2 sepura Information The STP8000 car kit is designed for 12 V negative earth systems. In vehicles with a 24 V supply, an approved converter must be used, NOT a 12 V tap on the battery. The equipment is to be installed in accordance with the requirements of local radio communications authorities and/or Health and Safety regulations. 12 V supply leads, antenna cables and speaker wiring is to be routed as far away as possible from gas or fuel lines. This reduces the risk to safety in the event of a leak. The car kit should be positioned so that it does not obstruct, or become at risk of damage from, any occupant or carried items. All cabling should be hidden and not left loose. Radio Software For correct operation of the STP8000 with the car kit, the STP8000 must have radio software of v9.0 greater. INSTALLATION This installation guide provides basic installation information and is not intended to be definitive, as different types of vehicles will require different ways installation arrangements. The installer must ensure that fixing screws of an appropri- ate length are used (some installations may require different screws). The information given here is general and for guid- ance only. The installation must comply with in-country CODE OF PRACTICE for the installation of mobile radio and related ancillary equipment in land based vehicles — e.g. FCS1362 (formally MPT1362)see http:// www.fcs.org.uk. WARNING 1 Disconnect the vehicle’s battery before commencing installation (be aware of effect on public broadcast radio security code, alarm systems and some engine man- agement systems). 2 Do not smoke, or use naked flames, when working near the vehicle’s fuel system. 3 Ensure that fuel lines, hydraulic lines and existing cables are not damaged during installation. 4 Ensure that the installation does not impede the normal operation of the vehicle, including the operation of any safety device, e.g., airbags and seatbelt tensioners. 5 Speed control, fuel injection, anti-lock braking, naviga- tion, air bag and other electronic systems are relatively immune to RF interference. However, if difficulty is experienced, or faulty operation suspected, consult the vehicle’s dealer. 6 This equipment is suitable for 12 V negative earth vehi- cles only. Use on other supply systems will result in damage to the equipment. 7 No part of the equipment should be mounted such that injury to the occupants is likely during an accident. 8 Prolonged operation of the radio in the car kit with the vehicle engine switched off, could drain the vehicle’s battery. 9 Prolonged operation at high volume levels may cause the interface unit to become hot. Cradle The cradle should be attached to the vehicle’s interior in a convenient position using the mounting brackets. The location of the cradle should allow the user unrestricted access to the radio’s controls. The radio’s display should be visible to the user but not distracting when driving. The cradle should not prevent the user from controlling or operating the vehicle. Interface Unit Attach the interface unit to the vehicle’s interior, using, if appropriate, the four 25mm self-tapping screws provided. The interface unit should be mounted on a firm surface in- side the passenger compartment, within reach of all cabling. The data socket should be easily accessible. Connect the lead from the cradle to the socket labelled “RADIO”. Con- nect the vehicle harness to the socket labelled “AUTO”. Note: Do not install the interface unit in engine compartment. Cables & Connectors Ensure the cables due not rub against sharp edges and are not subjected to undue stress. Power Connection (thick red and black wires) • The positive power line must include a fuse as close as possible to the power source. The negative power line must be connected close to the battery-to-vehicle-body connexion (not directly to the battery) and must not include a fuse. • It is recommended that the power cable runs are kept as short as possible. • The blue wire provides an ignition sensing input. If ignition switching is required, trim the wire to length so that it can be wired, via a fuse, to the ignition switch, using the splicing connector provided. Otherwise this wire must be connected, via a fuse, to the permanent positive supply. A fuse must always be fitted close to where the wire is connected. Fuse Ratings Positive supply 4 A Ignition sense 1 A The ring terminated wires are for direct connection to the vehicle battery (do not connect at this stage); supply should not be taken from any other point. Feed the bullet terminated free ends through the bulkhead, using a grommet to protect the wires.

SPR-DOC-003060 Vehicle Antenna Installation Guide sepura Sepura plc, Radio House. SPR-DOC-03060 St Andrews Road, Cambridge CB4 1GR Issue 1 www.sepura.com INTRODUCTION When installing any TETRA antenna to a vehicle, it is the responsibility of the installer to ensure that the location of the antenna is considered not only for best RF performance but more importantly in order to minimize the potential for RF exposure to third parties. To minimise the potential risk of RF exposure to third parties, antennas should ideally be fitted to locations on the vehicle that ensures that the distance between the radiating antenna and third parties is at least 20cm or if greater the minimum safe distance required to meet the General Exposure limit for that antenna fitted. If this General Exposure distance cannot be met then the radiating antenna must be placed in a location that ensures the Occupation limit cannot exceeded. A list of minimum distances for Sepura supplied TETRA antennas are shown in table 1 below. The outline drawing below shows one example of how third parties may come into proximity of the installed antenna. Should it not be possible to maintain the minimum safe distance between third parties and the radiating antenna, then action must be taken by the installer to reduce the potential for exposure at the specified minimum distance such that the General Exposure limits are not exceeded.

Date 3 rd September 2012 BABT Forsyth House Churchfield Road Walton-on-Thames Surrey KT12 2TD We, Sepura believe it is safe to use the Occupational limits for RF Exposure for all our Carkit and Mobile installations because:- • Under normal operating conditions the vehicles concerned will be in motion therefore members of the general public will not be exposed to the occupational RF exposure level for any length of time that could be considerate to pose a risk to them. • Given the nature of our customer base ie utility companies etc, when the vehicle is stationary it would normally be in a location that is not accessible to the general public.

It does not, however, conform to all of our Part 90 technical rules. The TETRA Association (the Association) 2 filed a request for waiver of the Part 90 occupied bandwidth limit and emission masks, in order to permit implementation of TETRA technology in the United States. For the reasons set forth below, we grant the waiver request in part, to permit certification and use of TETRA equipment, subject to certain conditions, pending the outcome of this rulemaking proceeding. II.BACKGROUND 2.Subpart I of Part 90 of our Rules sets forth the general technical requirementsfor use of frequencies and equipment in the private land mobile radio services. Such requirements include standards for acceptability of equipment, frequency tolerance, modulation, emissions, power, and bandwidths. 3 The purpose of these technical standards is to limit wireless systems’ interference potential. 4 The Association 1 47 C.F.R. Part 90. 2 See Request for Waiver of Sections 90.209, 90.210 and 2.1043 (filed November 20, 2009) (Request).
