QC0153GSMSignalAnalyser
1. Description
This manual documents the use of the following products:
• D2366-UK – Quad band GSM Signal Analyser with UK plug-top charger
The GSM Signal Analyser is a signal analyser for use with GSM radio networks. It is suitable for
testing where automatic signalling equipment is used, including smart metering and any
communication equipment that requires GSM to operate correctly. It may be used to position an
aerial and to test the performance of aerial systems.
The GSM Signal Analyser displays mobile network information including network provider
names, cell identities, frequencies and signal strength. Jamming signals may also be detected.
The GSM 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 suitable car
charger.
To improve battery performance and life, please ensure you charge the battery for a
minimum of 12 hours before first use.
If the GSM Signal Analyser is left switched on and unused, the unit will automatically switch
off after a preset time.
The GSM Signal Analyser is contained within a strong protective sleeve and is supplied
complete with a charger and manual.

6. RESULTS Screen
(See note below and section 11
for information)
GSM cells will be displayed in
decreasing order of signal strength.
If a number, and not the name of the
network, is shown, another network
search should be done (see section 10).
Press the right button to display the next
cell (weaker signal).
Press the left button to display the
previous cell (stronger signal).
Press the down button to return to the
Main menu.
In the main menu, scroll down then use the
right arrow to enter the Monitor Screen.
7. MONITOR Screen
(See section 12 for information)
The display is updated every 8 seconds. It
will normally show the strongest cell.
This display is used to locate an area for
the strongest signal strength.
Use this position when installing the aerial.
(See section 16 for more information)
Press the down button to return to the
Main Menu.
8. Select a new survey etc... as required.

4. SiteSurvey
It is recommended that a site survey is conducted prior to installation of any GSM 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 GSM 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 GSM Signal Analyser to find the point of best signal. This means maximising the signal
strength.
Full details on optimising signal strength are in section 16.
5. FittingaSIMcard
Note: Before inserting or removing a SIM card, please make sure the unit is switched off.
To access the SIM card holder, simply remove the GSM 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 GSM
Signal Analyser.
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.

Follow the on-screen
instructions to enter your
PIN then press down to
validate.
Alternatively pressing
up twice will take you
back to the use saved
PIN/enter PIN menu
Enter the SIM card’s PIN number the first time the SIM card is used. Once the GSM Signal
Analyser has shut down, this PIN number will be kept in memory until another PIN is entered.
In case of an incorrect PIN number, the following screens will be shown:
P l e a s e w a i t . . .
S I M : W r o n g P I N
then
D y c o n L t d .
G S M S i g n a l A n a l y
s e r V 3 . 2 9
E r r o r : G S M F a u l t 5
Press Up or Down arrows to get to the Main Menu.
In order to enter the correct PIN number, turn the GSM Signal Analyser off then power it up
again. The screen with the “Use saved PIN?” or “Enter PIN” options will appear. Choose “Enter
PIN” and follow the instructions on the next screen.
NOTE: the SIM card will be locked after 3 failed attempts at entering the correct PIN code. To
resolve a locked SIM you will need to contact the SIM card supplier for a PUK code and enter
this using a suitable mobile phone.

Max Cells = decrease the number of cells to find during survey
(3)
Auto Off = decrease minutes to auto-power off

Load Defaults = no action
Notes:
(1)
This allows positioning of the GSM Signal Analyser in a location and for the surveyor to
retreat before the survey starts.
(2)
The selected settings will remain active until the GSM Signal Analyser is switched off.
(3)
The default is 50 cells. This is the number of cells found, not the number of cells which
are OK. Reducing this number will reduce the time to complete a survey in a high
coverage area. If you are looking for a particular network’s results, reducing this number
may mean you will not see all available cells on your network. To perform a survey on a
particular network, use the facility in the Monitor screen to lock onto a network, then do
the survey.
