Introduction
Scanlock ECM is a radio recerver designed for rapid detection, identification and location of
hidden transmitters used for eavesdropping purposes.
Scanlock's advantage over conventional counter - surveillance equipment lies ir> its ability to
Scanlock continues to search for any new, stronger signal.
SuoDOse a low-powered transmitter is concealed at one end of a room. If Scanlock is located
anne other enS^en at that posrrion the strongest signal may be due to a local radicrstation.
^t^S^SS^^ transmission will be heard. As Scanlock is moved about the room a
oosmon Son be reached where the strength of the low-powered transmitter ,s greater than
+Ph°? °° ™It radio Son due to the now diminished distance between Scanlock and the
co^ceaTec^SS£^^^^ tune automatically to this signal and the transmitter
wTbe heard Scanlock's facilities enable the operator to confirm the presence of an eaves
dropping transmitter and to physically locate it with ease.
It is this combination of Scanlock's fast automatic tuning and the fact that it can be moved
during the aromatic tuning operation to minimise the distance between It and any concealed
transmitter that makes Scanlock highly effective and easy to operate.

In add-on to detecting, identifying and locating conventional transmitters, that is, those which
raSate the r signals through an antenna into the surrounding space, Scanlock can detect
SscSe? or current carrier' devices and other low frequency transmtfters that transmrt
aTonq a paif of AC power cables (from which they normally draw their power) or other cable
Sin oreference to the surrounding space. The eavesdroppers receiver is connected at a
^o^T^bc^q. Generally, receivers to detect such transmitters are available only
separately and may be expensive.
Other Applications
EavesdroDDinq transmitters are not only used to eavesdrop on conversation, they can be used
tc> checS^property is empty and therefore unguarded. Illegal entries into property us,ng this
technique to reduce risk have been reported in the national press.
Tracking transmitters attached to vehicles can be detected, identtfied and located using
Scanlock.
Guarantee
The equipment is guaranteed for a period of two years from the dote of original Purchase.
