1. INTRODUCTION 1.1. Scope and Purpose of Document This handbook is for use solely with the equipment identified by the Axell Wireless Limited (AWL) Part Number shown on the front cover. It is not to be used with any other equipment unless specifically authorised by AWL. This is a controlled release document and, as such, becomes a part of the Axell Wireless Total Quality Management System. Alterations and modification may therefore only be performed by Axell Wireless.
2. SAFETY CONSIDERATIONS 2.1. Earthing of Equipment Equipment supplied from the mains must be connected to grounded outlets and earthed in conformity with appropriate local, national and international electricity supply and safety regulations. 2.2.
2.5. Chemical Hazard Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used in devices within equipment produced by Axell Wireless Ltd. Beryllium oxide dust can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by contact. Products that contain beryllium are load terminations (dummy loads) and some power amplifiers. These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown above).
3. Equipment Overview 15 Channel UHF Hybrid Select Repeater 50-157401 The repeater consists of 10 rack mount chassis housed in a 43U, 19” equipment mounting rack Downlink signals are received from the RX antenna and passed into the Downlink Splitter/Combiner shelf 50-157402. The signal is passes through a bandpass filter to remove out of band noise and then passes through a low noise amplifier.

5. INSTALLATION 5.1 Initial Installation Record When this equipment is initially commissioned, please use the equipment set-up record sheet in Appendix B. This will help both the installation personnel and Axell Wireless should these figures be needed for future reference or diagnosis. 6. Fault Finding & MAINTENANCE 6.1 General Fault Finding Procedures In the event that the performance of the system is suspect, a methodical and logical approach to the problem will reveal the cause of the difficulty.
6.3 Uplink Testing the uplink involves a similar procedure to the downlink except that the frequencies used are those transmitted by the mobile equipment. 6.4 Fault repair Once a faulty component has been identified, a decision must be made on the appropriate course to carry out a repair. A competent engineer can quickly remedy typical faults such as faulty connections or cables.
6.8 General Maintenance Procedures Many of the active modules contain semiconductor devices utilising MOS technology, which can be damaged by electrostatic discharge. Correct handling of such modules is mandatory to ensure their long-term reliability. To prevent damage to a module, it must be withdrawn/inserted with care. The module may have connectors on its underside, which might not be visible to the service operative. 6.
6.12 Low Power Amplifier Replacement Disconnect the mains power supply and disconnect the 24V dc supply connector for the LPA. Disconnect the RF input and output cables from the LPA. Disconnect the alarm connector. Remove the alarm monitoring wires from (D type connector) pins 9 and 10. Remove the LPA module by removing the four retaining screws, replace with a new LPA module and secure it with the screws. Connect the RF cables to the LPA input and output connectors.
