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 Selective Cell Enhancer is a 2-way on-band repeater. Various models are
available to cover frequency bands from 50MHz to 3000MHz. Its main 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 and tunnels,
etc.,)
The Channel Selective Cell Enhancer is a 2-port device for direct connection to two
antennas, usually a highly directional Yagi or similar aligned towards the base (donor) site
and an omni-directional antenna to cover the mobiles. 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.
The rack-mounted version is usually supplied in 3 units, a power supply unit and 2 RF units
(one containing each path). Each shelf/tray unit containing active modules has a ‘D.C. on’
indicator on the front panel and the PSU also has an ‘A.C. on’ indicator.
The wall-mounted version is supplied in a single environmentally-protected case. Handles
are provided for carrying the unit and the door is fitted with locks. A supply isolator switch
is fitted inside the unit and there are ‘.DC. on’ and ‘Alarm on’ indicators on the outside of
the door.
