INTRODUCTION
Scope
This handbook is for use solely with the equipment identified by the AFL Part Number shown on the front cover. It is not to be used with any other equipment unless specifically authorised by Aerial Facilities Limited. This is a controlled release document and, as such, becomes a part of Aerial Facilities’ Total Quality Management System.

Purpose
AFL recommends that the installer of this equipment familiarise his/herself with the safety and installation procedures contained within this document before installation commences.
The purpose of this handbook is to provide the user/maintainer with sufficient information to service and repair the equipment to the level agreed. Maintenance and adjustments to any deeper level must be performed by AFL, normally at the company’s repair facility in Chesham, England.
This handbook has been prepared in accordance with BS 4884, and AFL’s Quality procedures, which maintain the company’s registration to ISO 9001: 1994 and to the R&TTE Directive of the European Parliament. Copies of the relevant certificates and the company Quality Manual can be supplied on application to the Quality Manager. This document fulfils the relevant requirements of Article 6 of the R&TTE Directive.
Limitation of Information Notice
This manual is written for the use of technically competent operators/service persons. No liability is accepted by AFL for use or misuse of this manual, the information contained therein, or the consequences of any actions resulting from the use of the said information, including, but not limited to, descriptive, procedural, typographical, arithmetical, or listing errors.
Furthermore, AFL does not warrant the absolute accuracy of the information contained within this manual, or it’s completeness, fitness for purpose, or scope.
AFL has a policy of continuous product development and enhancement, and as such, reserves the right to amend, alter, update and generally change the contents, appearance and pertinence of this document without notice.
All AFL products carry a twelve month warranty from date of shipment. The warranty is expressly on a return to base repair or exchange basis and the warranty cover does not extend to on-site repair or complete unit exchange.

1. SAFETY CONSIDERATIONS
1.1 Earthing of Equipment
Cell Enhancers 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.
1.2 Electric Shock Hazard
Electrical shocks due to faulty mains driven power supplies. Whilst ever potentially present in any electrical equipment, such a condition would be minimised by quality installation practice and thorough testing at:
a) Original assembly
b) Commissioning
c) Regular intervals, thereafter.
All test equipment to be in good working order prior to its use. High current power supplies can be dangerous because of the possibility of substantial arcing. Always switch off during disconnection and reconnection.

1.3 RF Radiation Hazard
RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to AFL’s equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a ‘spare’ output has been left unterminated. Either of these conditions would impair the system’s efficiency. No investigation should be carried out until all RF power sources have been removed. This would always be a wise precaution, despite the severe mismatch between the impedance of an N type connector at 50, and that of free space at 377, which would severely mitigate against the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended.
Where the equipment is used near power lines, or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised.

1.4 Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used in devices within equipment produced by Aerial Facilities 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). They are marked as hazardous in line with international regulations, but pose no threat under normal circumstances. Only if a component containing beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the formation of dust. Any dust that has been created will be contained within the equipment module as long as the module remains sealed. For this reason, any module carrying the yellow and black danger sign should not be opened. If the equipment is suspected of failure, or is at the end of its life-cycle, it must be returned to Aerial Facilities Ltd for disposal.
To return such equipment, please contact the Quality Department, who will give you a Returned Materials Authorisation (RMA) number. Please quote this number on the packing documents, and on all correspondence relating to the shipment.
PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials
Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation barrier. This material should never be heated to the point where smoke or fumes are evolved. Any person feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes should seek medical attention.
1.5 Emergency Contact Numbers
The AFL Quality Department can be contacted on:
Telephone +44 (0)1494 777000
Fax +44 (0)1494 777002

2. OVERVIEW/SYSTEM DESCRIPTION
The AFL Channel and/or Band Selective Cell Enhancers are 2-way on-band repeaters. Various models are available to cover frequency bands from 50MHz to 3000MHz. The principle sphere of applications is in urban areas where the topology is such that shadows occur in the propagation pattern (for example within large buildings, conference centres, road and rail tunnels, etc.)
The frequency bands that are passed by the Cell Enhancer are set as per the specific customer requirements.
AFL manufacture a wide range of Cell Enhancers, configured for each customer's specific requirements. Two basic physical variants are available, a rack mounted version to fit in a standard 19" rack and an environmentally sealed wall mounted version which requires no further enclosure.
This system provides 800MHz Channelised (x 24) & VHF Simplex/Duplex coverage for the various concourses platforms and tunnels with a 12V battery backup service (for the 800MHz line amplifier) that will guarantee limited continued coverage in case of mains power failure.
Each active module is alarm monitored with each shelf/ wall-case having a summary alarm with a visual ‘alarm active’ indication and a door intrusion alarm included for the wall cases. All alarms are volt-free, relay contact pairs which may be easily configured into an RS232/modem system such that automatic remote monitoring by computer may be achieved.
