1. INTRODUCTION
Scope and Purpose of Document
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. Alterations and modification may therefore only be
performed by Aerial Facilities Ltd.
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 BS EN ISO 9001:2000 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 Liability 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.

SAFETY CONSIDERATIONS
2.1
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.
2.2
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.
2.3
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 50Ω, and that of free space at 377Ω, 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.

2.4
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.
2.5
Laser Safety
General working practices adapted from EN60825-2: 2000
“Do not stare with unprotected eyes or with any unapproved optical device at the fibre
ends or connector faces or point them at other people.”
“Use only approved filtered or attenuating viewing aids.”
“Any single or multiple fibre end or ends found not to be terminated (for example,
matched, spliced) shall be individually or collectively covered when not being worked
on. They shall not be readily visible and sharp ends shall not be exposed.”
“When using test cords, the optical power source shall be the last connected and the first
disconnected.”
“Use only approved methods for cleaning and preparing optical fibres and optical connectors.”
Always keep optical connectors covered to avoid physical damage
Do not allow any dirt/foreign material ingress on the optical connector bulkheads.
The optical fibre jumper cable maximum bend radius is 3cm, any smaller radii may result in optical
cable breakage or excessive transmission losses.
Caution: The FO units are NOT weather proof.

FAULT FINDING & MAINTENANCE
5.1
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.
Transmissions from the main base stations are passed though the system to the mobile radio
equipment; this could be a handheld radio or a transceiver in a vehicle. This path is referred to as the
downlink. The return signal path from the mobile radio equipment to the base station is referred to as
the uplink.
The first operation is to check the alarms of each of the active units and determine that the power
supplies to the equipment are connected and active.
This can be achieved remotely (via CEMS, the RS232 Coverage Enhancement Management System,
if fitted), or locally with the front panel LED’s. The green LED on the front panel should be illuminated,
while the red alarm indicator should be off.
If an Alarm is on, then that individual shelf/module must be isolated and individually tested against the
original test specification.
The individual amplifier units within the shelf have a green LED showing through a hole in their piggyback alarm board, which is illuminated if the unit is working correctly.
If an amplifier is suspect, check the DC power supply to the unit. If no other fault is apparent use a
spectrum analyser to measure the incoming signal level at the input and then after reconnecting the
amplifier input, measure the output level. Consult with the system diagram to determine the expected
gain and compare result.
In the event that there are no alarms on and all units appear to be functioning it will be necessary to
test the system in a systematic manner to confirm correct operation.
Handbook Title:-BDA
User Handbook
Handbook No. 60-137705HBK
Page: 12 of 20
5.2
Downlink
Confirm that there is a signal at the expected frequency and strength from the base station. If this is
not present then the fault may lay outside the system. To confirm this, inject a downlink frequency
signal from a known source at the master site BTS input and check for output at the remote site
feeder output.
If a signal is not received at the output it will be necessary to follow the downlink path through the
system to find a point at which the signal is lost. The expected downlink output for the given input can
be found in the end-to-end test specification.
5.3
Uplink
Testing the uplink involves a similar procedure to the downlink except that the frequencies used are
those transmitted by the mobile equipment.
5.4
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. The exceptions to this are cable assemblies connecting bandpass filter assemblies that are
manufactured to critical lengths to maintain a 50-ohm system. Care should be taken when replacing
cables or connectors to ensure that items are of the correct specification. The repair of component
modules such as amplifiers and bandpass filters will not usually be possible in the field, as they
frequently require specialist knowledge and test equipment to ensure correct operation. It is
recommended that items of this type are replaced with a spare unit and the faulty unit returned to AFL
for repair.

5.5
Checking service
Following the repair of any part of the system it is recommended that a full end-to-end test is carried
out in accordance with the test specification and that the coverage is checked by survey.
It is important to bear in mind that the system includes a radiating cable network and base stations
that may be faulty or may have been damaged.

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.
5.9
Module Removal (LNA’s, general procedure):
The following general rules should be followed to remove a module:
Remove power to the unit
Remove all visible connectors (RF, DC & alarm)
Release module retaining screws.
Slowly but firmly, pull the module straight out of its position. Take care not to twist/turn the
module during withdrawal. (When the module is loose, care may be needed, as there may be
concealed connections underneath).
5.10
Module Replacement (general):
Carefully align the module into its location then slowly push the module directly straight into its
position, taking care not to twist/turn it during insertion.
Reconnect all connectors, RF, alarm, power etc.,(concealed connectors may have to be
connected first).
Replace retaining screws (if any).
Double-check all connections before applying power.
5.11
1)
Power Amplifiers
Remove power to the unit. (Switch off @ mains/battery, or remove DC in connector)
2)
Remove alarm wires from alarm screw terminal block or disconnect multi-way alarm
connector.
3)
Carefully disconnect the RF input and output coaxial connectors (usually SMA)
If alarm board removal is not required, go to step 5.
4)
There is (usually) a plate attached to the alarm board which fixes it to the amplifier, remove its
retaining screws and the alarm board can be withdrawn from the amplifier in its entirety. On certain
types of amplifier the alarm board is not mounted on a dedicated mounting plate; in this case it will
have to firstly be removed by unscrewing it from the mounting pillars, in most cases, the pillars will not
have not have to be removed before lifting the amplifier.
5)
If the amplifier to be removed has a heatsink attached, there may be several different ways it
can have been assembled. The most commonly used method, is screws through the front of the
heatsink to threaded screw holes (or nuts and bolts), into the amplifier within the main case. If the
heatsink is mounted on the rear of the main case (e.g., against a wall in the case of wall mounted
enclosures), then the fixing method for the heatsink will be from within the case, (otherwise the
enclosure would have to be removed from the wall in order to remove the heatsink).

When the heatsink has been removed, the amplifier may be unscrewed from the main casing by its
four corner fixings and gently withdrawn.
Fitting a new power amplifier module will be the exact reverse of the above.
Note: Do not forget to apply fresh heatsink compound to the heatsink/main case joint and also
between the amplifier and the main case.

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. Reconnect the wires to the alarm
board connector pins 9 and 10.
Reconnect the DC supply connector and turn the mains switch on.
Note: Tighten SMA connectors using only a dedicated SMA torque spanner. If SMA connectors are
over-tightened, irreparable damage will occur. . Do not use adjustable pliers to loosen/tighten SMA
connectors.
Also take care not to drop or knock the module as this can damage (or misalign in the case of tuned
passive modules) sensitive internal components. Always store the modules in an environmentally
friendly location

Module Transportation:
To maintain the operation, performance and reliability of any module it must be stored and
transported correctly. Any module not installed in a whole system must be kept in an anti-static bag or
container. These bags or containers are normally identified by being pink or black, and are often
marked with an ESD label. Any module sent back to AFL for investigation/repair must be so
protected. Please contact AFL’s quality department before returning a module.

If the input signal level in the uplink path is known and steady, use the following calculation table to
determine the gain setting. If the CE features Automatic Gain Control the attenuator should be set to
zero and if not, then the attenuation setting for both uplink and downlink should be similar.
