In a "clean" environment, with all known wireless and mobile devices deactivated, the bargraph of an

RF detector shows the "near to zero" level. In this situation the user will observe the slightest increase

on the bargraph caused by a bugging transmitter even at a long distance.

In a real urban environment there are a huge number of different transmitters including broadcasting,

communication and portable wireless devices. A typical RF detector (near-field receiver) receives these

signals and shows a constantly increased level on the bargraph. This results in decreasing the detecting

distance as the bugging signal must exceed the constant background to be detected.

The iProtect 1216 has a big advantage compared to conventional RF detectors and near-field receivers.

While the general sensitivity of a typical near-field receiver drops near any interference, the

iProtect 1216 decreases the sensitivity of just one band and maintains a high sensitivity on others.

Some signals will be detected by the 1216 at a distance of 2-3 meters, while others – at 10-20 cm.

For maximum possible security it is recommended to probe the surfaces and objects at a distance

of 10 cm.

Checking landline phones

Telephone bugs may be installed anywhere a phone line lays. It may be within the phone set, the

phone outlet, connecting box or cable. Most telephone bugs activate only when the receiver is

off-the-hook. Therefore the sweeping of phone lines should be carried out only when the receiver is in

this state. Move along the phone line and probe it while your assistant picks and hangs up the phone

periodically. Watch for the presence of changes on the bargraphs. A high RF level might well mean the

presence of transmitter.

The iProtect 1216 will react to cordless phones since they send radio signals. The DECT cordless

phones should be detected by the Band 2 with the corresponding message on the signature display -

"DECT Idle" or "DECT Active".

The presence of a high RF level on the Band 2 at a distance of 1-2 meters to a DECT device is normal.

At the same time the presence of a high RF level on the Band 1 and 3 should be treated as "suspicious".

Battery

The iProtect 1216 has a built-in rechargeable battery providing a resource of up to 6 hours.

As the battery becomes discharged the corresponding label on the status display will change:

OK – fully charged

MED. – charged 30-80%

LOW. – less than 30% left

The 1216 will turn off automatically when its battery is discharged to the crucial level.

You can recharge the detector from any USB port, including of the laptop, cell phone charger or car USB

adapter. Recharging time is 4 hours.

The detector can be operated during recharging.
