Operation Manual
Description
The D2366 is a radio signal analyser for use with GSM and GPRS radio networks where
automatic signalling equipment is used, including the D2300, D2400 and D2600 ranges of Dycon
products. It may be used to position an aerial and to test the performance of aerial systems.
The GSM radio signal analyser will measure and display radio signal strength received, plus
levels of interference may be measured and sources of interference identified.
The GSM radio signal analyser contains a battery allowing remote operation for up to 12 hours.
The internal battery may be recharged from the supplied mains power supply or a car lighter
socket.
If the GSM radio signal analyser is left switched on and unused, the unit will automatically switch
off after a preset time.
The GSM radio signal analyser is contained within a strong protective sleeve and is supplied
complete with a charger and manual.
Warning – only use with the supplied charger.

Site Survey
It is recommended that a site survey is conducted prior to installation of any GSM or GPRS
equipment and associated aerial system to confirm that an adequate radio signal is available at
the site.
It is particularly important that a site survey is conducted when:
a. there may be a weak signal strength at the proposed site;
b. it is known that the aerial will be fitted inside a sheet metal covered building or under
a sheet metal roof;
c. the aerial will be on lower floors of buildings in heavily built-up areas.
The D2366 GSM radio signal analyser is ideal for surveying a proposed site for a suitable radio
signal. Note the point of best signal. Install the aerial at this location.
Use the radio signal analyser to find the point of best signal. This means:
- Maximise the SIG (high signal strength received from a base station);
- Minimise the BER (none or low level of interfering signals).
Full details on optimising signal strength and BER are on pages 16 and 17.
Fitting a SIM card
To access the SIM card holder, simply remove the D2366 GSM radio signal analyser out of the
rubber sleeve from the bottom end. You will find a small yellow button - press on it with a pen
and the SIM card holder will be ejected. Fit the SIM card onto the holder and push the latter back
into the D2366.
When no SIM card is fitted, the unit will display results for all networks detected.
When a SIM card is fitted, the unit will be locked to that operator’s network.

Aerial Siting
ALWAYS do a site survey to find the point of best signal before installation.
The aerial should be mounted vertically at the point of best signal. This is usually the highest
point in the building (often the loft area). For security applications, the position chosen should be
inside the protected area.
Large metal structures can affect radio signals. Therefore, whenever possible, avoid installing
the aerial directly under sheet metal roofs or within sheet metal covered buildings because this
will reduce the signal strength. If this is unavoidable, the strongest signal will be found away from
the metal roof or close to large external windows or skylights.
Many large buildings closely spaced together will reduce the signal strength, particularly for
aerials on the lower floors, e.g. ground floor installation in city centres. The strongest signal will
normally be found close to external windows or skylights as high as possible.
Wherever possible, do not install the aerial close (2 metres) to sources of interfering signals.
These include: fluorescent or neon lighting, power distribution panels, power cable runs, fridges,
freezers, air-conditioning and ventilation equipment as well as electronic equipment, e.g.
photocopiers, fax machines, computers, televisions...
Reliable radio operation is unlikely with low signal strength, with an incorrectly installed aerial or
with strong interfering signals.
Use the test set to find the point of best signal. This means:
- Maximise the SIG (high signal strength received from a base station);
- Minimise the BER (none or low level of interfering signals).
The supplied short black aerial is for hand-held use, i.e. site surveys.
OR
Use an aerial adapter to connect and test a remote aerial.
Remember: It is always easier to find the point of best signal before the equipment is fitted on
the wall. Moving aerials, cables, trunking... after installation is wasted time and effort.

D2366 GSM Radio Signal Analyser – Operation Manual – D2366-OPS2/EU/F10/v4 - 17

BER (Bit Error Rate)
The BER (Bit Error Rate) is the level of GSM interfering signals received by the GSM radio signal
analyser.
The BER measurement in the Result screen may be used to detect GSM radio signals that are
being corrupted by interfering radio signals.
Sources of interfering signals may be: fluorescent or neon lighting, power distribution panels,
power cable runs, fridges, freezers, air-conditioning and ventilation equipment as well as other
electronic equipment, e.g. photocopiers, fax machines, computers, televisions...
This test may be used with a mobile aerial to detect locations where interfering signal strengths
are stronger or weaker.
When determining a position for an aerial, for best performance, select a location where there are
no effects from interference. See page 16.
In most cases, interfering sources only radiate short distances so that relocating the aerial 2 to 4
metres away from the source will cure interference effects.
When the BER measurement in the Results screen shows Good
The measured BER value indicates none or low levels of interference.
This is the ideal BER reading that can only be achieved by locating the aerial away from sources
of interference.
When the BER measurement in the Results screen shows Poor
The measured BER value indicates low or medium levels of interference.
Where occasional interference corrupts some data, the automatic error correction will repair this
level of interference. Reliable radio operation should not be expected.
When the BER measurement in the Results screen shows Bad
The measured BER value indicates medium or high levels of interference.
Error correction may repair some of the corruption caused by interference but reliable operation
should not be expected in all instances. High levels of interference may completely inhibit
operation. Relocation of the aerial to improve the BER is essential.


Battery and Charging
Before first use, fully charge the battery.
When charging, use only the supplied mains plug-top power supply.
A completely flat battery will recharge within 3 hours (typically 2 hours).
A fully charged battery will operate the test set for up to 12 hours.
The battery state may be read on the Monitor screen. See page 14.
When the charger is connected, the unit is always on and the On/Off button will not turn the unit
off.
When the charger is disconnected, the GSM radio signal analyser will automatically switch off
within one minute or after the preset time has expired.
If the GSM radio signal analyzer is left switched on and unused (no buttons are being pressed),
the unit will automatically switch off after a preset time to preserve the battery life. The preset
time may be changed in the Setup screen. See page 9.
The internal battery is a Solid Electrolyte Lithium long type that may be transported, charged and
used in any orientation. It should be protected from frost and temperatures above 40°C.
As with all rechargeable batteries, over several years, its capacity to store power will degrade. If
the operational life of the battery reduces below 1 hour, contact your supplier for replacement
information.
Do not attempt to open the case or remove the battery.

Glossary of Terms
BER – Bit Error Rate
A count or level of interfering signals received by the test set.
CELL – Cellular Identity Number
A number to uniquely identify each GSM/GPRS base station in the UK.
FSSI – Forward Signalling Strength Indication
This is a value indicating the radio signal strength received from the base station at a
GSM communicator or the GSM radio signal analyser.
GPRS – General Packet Radio Service
A packet-based network, within the GSM system, where cost is determined by data
quantity (as distinct from a circuit switched network, where cost is determined by time).
Data rates range from14.4kbps, using just one of the available TDMA time slots, up to a
theoretical 115 kbps when all eight time slots are used. Being a packet-switched system,
the bandwidth within each GPRS cell sector will be divided between all the subscribers.
GSM – Global System for Mobile communication
A second generation cellular telecommunication system, originally for Europe, now global.
A circuit-switched network, where cost is determined by time. It operates in 3 frequency
bands: 900MHz, 1800MHz and 1900MHz.
SIM – Subscriber Identity Module
This is usually referred to as a SIM card. The SIM is the user subscription to the mobile
network. The SIM contains relevant information that enables access onto the subscripted
operator’s network.
