munication protocols only. For full, irrefragable results the premises or vehicle

should be swept with a number of different types of equipment, including wide-

band RF detectors, radio-monitoring scanning systems, non-linear junction

detectors, video-camera detectors, thermal vision devices, etc.

A wireless detector is an additional but irreplaceable component for such a

professional kit and due to its qualities the Protect 1207i is the best selection.

Before starting sweeping, some preparation tasks should be carried out.

Firstly, it is necessary to consider the time and individual circumstances of the

sweep. Due to there being lots of devices which are remotely controlled it is

recommended to carry out a sweep during working hours in real situations

when the eavesdropper most wants to listen. It may be necessary to arrange a

fictitious meeting. Nobody has to know about the pending search.

Close all drapes in the room. Turn on all the lights and activate any other

devices to imitate normal conditions. It is also advisable to turn on a source

of sound such as a stereo system or radio. This sound source has two very

important functions:

Voice activated transmitters will be activated

Your actions will be masked

Enter the room and turn on your Protect 1207i. Watch the bar graphs and

if they show increased levels (more than 4-5 segments), turn on the atte-

nuator by shifting the joystick in the upper direction (ATT+).

The corresponding LED will show the attenuator has been turned on.

Note: Later you can turn off the attenuator by pushing the joystick in the

opposite direction.

Choose the operation mode by sequentially shifting the joystick to the right:

Silent - the default mode which is automatically selected after turning

the unit on. It can also be selected in the sequence of modes (joystick

right) or chosen quickly by shifting the joystick to the left. This mode

is useful when a covert procedure is necessary.

The Listen mode is more convenient for locating and inspecting

the RF source as the operator can learn about the source by hearing

the demodulated signal. An experienced operator may be able to

distinguish between different kinds of transmission:

Bluetooth gives a 'crackling' sound

Wi-Fi will produce a 'scratching' sound

GSM gives a 'buzzing' (hum)

DECT is heard as an AC transformer hum

Note: The above is a guideline only as the sound may vary depending

on the current mode of transmission and the type of the protocol used

in the specific country.

The Listen mode can be turned on temporarily from any mode by

pressing and holding the joystick's button.
