Parts and controls

1. ‘Pulse’ indicator. This LED lights up when a pulse field is present near the unit. Such a field is usually produced by GSM/DECT telephones or can be created by a bugging device with a ‘non-standard’ type of transmission.

2. Indicators of working mode

3. Button for selection of working mode:

• Normal. In this mode the Protect 1210 will indicate an increase of the RF level on the bar graph. No sound will be produced.
• Sound. In this mode the Protect 1210 will produce the sound of a demodulated signal. In close vicinity of the FM-modulated bugging device a loopback effect should appear. A buzzing sound will appear near digital transmitters like an active GSM phone. This mode allows the user to identify the transmitter.
• Vibro. This mode is used for covert operation or for situations when the operator cannot watch the bar graph. An increase of the RF level will cause the built-in vibrator to activate.
• Sleep. In this mode the Protect 1210 wakes up every 3 seconds and checks the current RF environment. If there is an increased level the unit will indicate this with an alarm sound. The detector will stay active until the high level disappears.

4. This indicator turns on when the battery is low and should be replaced

5. Power on/off

6. Speaker

7. Bar graph indicator. Displays current level of the electromagnetic field and helps the user to locate bugging devices. Location is carried out by moving the unit into the strongest level area. The barograph consists of 8 LEDs and shows the current level with the help of 3 of them at any one time. As the field becomes stronger this group scrolls up. For powerful signals the group goes up further until two or one diode remains on.

8. Indicator of the current sensitivity level

9. Zeroing the sensitivity of the detector according to the current RF level. The unit will store the current level and clear the bar graph so that it will show stronger signals only. Perform this action before approaching the target zone or when you are trying to locate the RF source. Use this control each time it is necessary to re-tune the sensitivity – when you enter an area with a lower or higher level of background noise.

Antenna

The antenna of the unit is situated on the rear side under the ‘Protect 1210’ label. It receives electromagnetic waves and passes them to the unit’s circuit board. It is necessary to direct this side of the detector towards probed items and surfaces when performing a search.
