Enter the premises and start scanning in the ALL BANDS mode, moving the device. The
iProtect 1217 is sensitive enough and can detect strong signals at a quite long distance, which
can reach 10 meters or so. Therefore, there is no need to scan the surfaces and internal cons-
tructions too closely, – move the device and approach the surfaces at a distance of 0.5-1 metre.
However, in order to find very weak signals, like Bluetooth, it may be required to move the
device closer to an object.
If you detect a noticeable increase in the radio frequency level in one of the bands, start a
physical search for the possible location of a transmitter.
Move the device and change the antenna direction in order to find where the signal is coming
from.
It is more convenient to locate signals above 2400 MHz thanks to the directional microwave
antenna. When the antenna is directed towards the transmitter, the level grows, thus the ope-
rator sees the direction towards the signal. If the band's frequency is above 2400 MHz, change
the device's direction in order to understand where the signal is coming from. Then move the
device and change the direction again. In such a way, you will be able to find the source of
the signal.
Localization of the signals under 2400 MHz is performed by moving the iProtect 1217 and by
successive approximation to the transmitter with an increase in the level. Divide the premises
into approximately 4 parts and measure the level in each part. Divide the part with the highest
level again into 4 parts and find the max level again. And so on. In such a way, you will be
able to find the source.
Physical locating can be performed while you stay in the ALL BANDS mode, or you can go on
to a more detailed inspection of a certain group or a band. In order to enter the group (GROUP
mode), first select it with the joystick and then press the button on the joystick. Next, inside of
the group, you can select a band and enter it (BAND mode). The BAND mode has a number of
advantages:
hear the sound alarm signal if desired. If you want to maintain the secrecy of the sweeping
operation, do not switch the sound on.
As you try to locate the transmitter, you can gradually raise the alarm threshold and thus narrow
the search area, paying attention to the sound (AUDIO and ALARM functions must me switched
on).
- the probability of detecting short-time signals (Wi-Fi, Bluetooth, 4G, 5G, etc.) increases;
- it is more convenient to inspect a separate band when there is a high activity on the others.
An audio alarm arises only from the band being inspected.
Position the device close to the target premises, switch it on and select the ALL BANDS mode.
Note the background level that exists in this place. Adjust the alarm threshold in such a way
that it is slightly higher than the background. Switch on the ALARM function to see visual
warnings about the detection of a high level of signal, and the AUDIO function – in order to
