First aid for electrical shock and safety rules 2.1 First aid for electrical shock Do not touch the patient with bare hands until the circuit has been opened. pen the circuit by switching off the line switches. If that is not possible protect yourself with dry material and free the patient from the conductor. 2.1.1  Artificial respiration It  is  important  to  start  mouth  resuscitation  at  once  and  to  call  a  doctor  immediately.  Suggested procedure for mouth to mouth resuscitation method is described in Table 1. 2.1.2  Treatment of burns This treatment should be used after the patient has regained consciousness. It can also be employed while artificial respiration is being applied (in this case there should be at least two persons present). Warning • Do not attempt to remove clothing from burnt sections • Apply dry gauze on the burns • Do not apply ointments or other oily substances.

Installation 6.1 Overview The device can be shipped preinstalled in a cabinet or not. If it is not shipped preinstalled in a cabinet, after unpacking, mechanical installation takes place, followed by electrical connections as described in this  document.  The  device  may  be  installed  in  any  location  suitable  for  electronic  communications equipment, provided that the environmental conditions do not exceed the equipment specifications for temperature,  humidity,  and  air  quality  and  that  the  access  to  that  location  is  restricted  as  described below: •  access can only be gained by service persons or by users who have been instructed about the reasons  for  the  restrictions  applied to the  location and about any  precautions  that be taken; and •  access  is  through  the  use  of  a  tool  or  lock  and  key,  or  other  means  of  security,  and  is controlled by the authority responsible for the location 6.1.1  Installation Pre-requisites To  ensures  the  best  possible  performance  and  reliability  of  the  described  equipment  pre-installation planning is required. This includes considering the mounting location of the repeater in relation to input power and  antennas.  Also to be  considered  are  site  environment conditions, the particular mounting method and required tools and equipment. To  plan  the  installation,  please  pay  particular  attention  to  environmental  condition  at  the  site, ventilation requirements, and grounding and lightning protection as described in this manual. After that, following the instruction given in this manual: •  Unpack and inspect the equipment. •  Mechanical install the equipment at the site. •  Make necessary electrical wiring: -  Unit Grounding -  DC input cabling -  Coaxial cables to transmit and receive antennas •  Perform a post-installation function checkout test of the equipment to verify proper installation. •  Proceed  to  customize  the  repeater  parameters  per  customer  specifications  (e.g.  operating frequency, PL, codes, color code, etc.)
 SELEX Communications  Information contained in this document may not be used, applied or reproduced for any purpose unless agreed by SELEX Communications S.p.A. in writing 16    July 2010    6.1.2  Unpack  Inspect the equipment for damage immediately after unpacking and make a report of the extent of any damage to the transportation company and to SELEX Communications S.p.A. The following items are packed together: •  ECOS-D A2T Radio Base Station •  DC power cable •  This manual 6.1.3  Mechanical installation The  device  is  shipped  in  a  box.  Upon  delivery,  the  equipment  must  be  removed  from  the  container (see Unpack section) and transferred to a rack or cabinet if not provided. If supplied, the metallic cabinet is a 6 RU 19” metallic cabinet. The cabinet is provided with 4 feet and it is stackable up to three cabinets. The cabinet is provided with two lateral handles to be used only for handling it  during the installation process. The Cabinet is  provided with front and  rear metallic doors with locks.  Refer to this manual for all the installation requirements even if the device is supplied with a cabinet. If  the  device  is  supplied  without  a  cabinet  it  is  designed  to  be  fitted  in  a  19”  cabinet  using  3  RU  of space.
 SELEX Communications  Information contained in this document may not be used, applied or reproduced for any purpose unless agreed by SELEX Communications S.p.A. in writing 17    July 2010     Customer-supplied cabinets and racks must have mounting rail and hole spacing compatible with EIA Universal  48.3  cm  (19  inches)  specifications.  Cabinets  must  provide  adequate  ventilation  and  must meet the following criteria: •  45.0 cm (17.71 inches) deep •  48.3 cm (19 inches) wide •  13.4 cm (5.25 inches) high •  Two mounting rails 5 cm (2 inches) from front cabinet with front mounting holes 5.7 cm (2.25 inches) apart (center to center). The front of the device is provided with four holes for M6 screws. This permits to fasten the device to a 19” rack by means of 4 M6 screws. If several devices are installed in a single cabinet, be sure equipment have to be spaced at least by 1/2 RU (2,2 cm, 0,8 inches).to allow for adequate cooling. Cabinets  must  have  a  least  15  cm  (6  inches)  of  open  space  between the  air  vents  and  any  wall or other cabinets. This allows adequate air flow. When multiple cabinets (each equipped with several repeaters) are installed in an enclosed area, ensure appropriate ventilation and consider air conditioning or other climate control equipment to satisfy the temperature requirements.

The  cable  terminates  to  flying  connectors  which  have  to  be  connected  to  the  corresponding connectors on the equipment front. Position  and  pin–out  of  the  equipment  connectors  are  available  in  the  appropriate  section  in  the following of this document. 6.1.5  Unit grounding The device is equipped with a ground nut located on the rear panel of the device and identified by a  label. This nut must be used for a direct connection of the device to the site grounding, even if the device is included in a cabinet. All antenna cables and DC power cabling should be properly grounded and lightning protected. Failure to provide proper lightning protection may result in permanent damage to the radio equipment.

It is able to operate with channel spacing of 12.5 kHz, 20 kHz and 25 kHz. Limitation on usable RF bands and channel spacing may apply due to local regulations. This  module  is  equipped  with  devices  for  numerical  computation  (DSP,  FPGA)  and  control (microprocessor) combined with the radio receiver front-end and the transmitter driver. The RTX module main functionalities are: •  Dynamic Dual mode radio operations with support of digital and analog modulation  •  Synchronization from external reference via CORE module •  Temperature control. •  UHF band: 400 – 470 MHz The  front  panel is provided with bi-color leds  to  help in troubleshooting the system.  The table below describes the meaning of the leds: LED  Color  Label  Description 1  Green  RX busy  RF signal present at the receiver  Red RX fail  Receiver PLL unlock  Red blink RX fail  RX Equalizer failure

Their time of TX ramp up/down is less than 1200 µsec. This makes the module compatible with the stringent demands of digital transmission. Thanks to a microprocessor mounted on board, the module is able to implement the  PUFF  technology  (Powerful  Universal Forming Function) for  the shaping of transient  power  in  order  to  obtain  compliance  with  the  rapid  transient  rules  of ACP (Adjacent Channel Power). The microprocessor also manages completely the operation of the module: this would  remove  any  calibration  procedures.  All  configuration  changes  are performed via software. Other main functionalities are: •  continuous transmitter’s operations (100% duty cycle). •  Output power selectable between two values (Phi and Plo), each of which can be SW set to a nominal value between 2 and 25 Watts.  •  final stage protected against excessive mismatching output power. In the case that VSWR remains  above  a  set  threshold  (eg  ReturnLoss  =  5dB)  for  more  than  a  fixed  time,  the module is able to send an alert and the output power will not exceed a safety value (eg ≤ 10watt).  •  temperature threshold alarm: if the temperature remains above a set value for more than a fixed time, the module is able to send an alert and will ensure that the RF output power will not exceed a predetermined safe value. The  front  panel is provided with bi-color leds  to  help in troubleshooting the system.  The table below describes the meaning of the leds:   LED  Color  Label  Description 1  Green  PWR High  High Power level selected and correctly On Air   Red PWR fail  Emitted  power  less  than  a  FW  configured  threshold  (3  dB typical) 2  Green  PWR low  Low Power level selected and correctly On Air
