- Touch panel of sensitivity regulation (item 8).
On the side surface of the body frame are located following items:
- microUSB jack (item 9) for connecting the charger (AC adapter and cable are included in the package
supplied);
- Charging indicator (item 10);
- Power switcher (item 11).
3. Structure and functioning.
3.1 The device runs under command of microcontroller with embedded software.
Before using the device put power switcher (item 11) into “ON” position (up).
3.2 The keyboard (item 2) has the following functions:
- Turning ON/OFF the device (press and hold the button "ON / OFF" not less than 3 seconds). When you turn on the
device it performs a self-test, a beep sounds, all the LEDs lights are up. By the end of the self-test "MODE" and
"BAT" LEDs remain on, signaling that the device is ready to operate.
- The sensitivity of the device is regulated upwards by moving your finger up the touch panel.
- The sensitivity of the device is regulated downwards by moving your finger down the touch panel.
- The device’s sensitivity automatically readjusts to the surrounding radiation level by double clicking the
touch panel.
3.3 Current sensitivity level of the device is displayed by smooth light of LEDs going up or down on the touch
panel. The higher is LED point on the touch panel, the higher is the sensitivity.
3.4 Operating modes of the device are switched by pressing "MODE" button:
a) When the "MODE" LED is on - the device is in constant search of analog signal.
b) When the "MODE" LED is flashing - the device is in search of pulse (digital) transmitters (digital
eavesdropping devices, cell phones).
c) When the "MODE" is off and "AK" LED lights up for short time period and then goes off - the device is in
guarding mode (detects only when new sources of signal appear). This operating mode allows to keep the device in
optimal sensitivity mode and significantly saves battery life.
3.5 Switching into functioning modes with additional audible alarm notification can be performed by pressing
"MODE" button (more than 3 seconds) and:
a) if LED "AK" is flashing – signal level alarm is enabled (frequency of acoustic signals depends on signal
strength).
b) if LED "AK" is steady – the device is in "feedback mode" (allows to detect wireless microphones in area up
to 0.5 m).
c) if LED"AK" is off - sound notification is disabled.
3.6 When the device is on, then, by briefly pressing "ON / OFF" button you can see level of battery charge on
the LED scale (item 7). If all 10 LEDS are on it means the charge is 100%, if 9 out of 10 LEDs are on – 90 % and
etc.
3.7 The blinking red light of the button ON/OFF (item3) backlight indicates the low battery charge.
NOTE: If you do not use the device for a long time, please put the power switch (item 11) to the OFF position
(down) in order to save battery charge.
4. Operation procedure:
4.1 Turn on the device by pressing "ON / OFF" button. The device will automatically adjust the sensitivity to
the level of surrounding radiation.
4.2 Start monitoring the room, keeping the device at 0.3-0.5 m distance from the tested surfaces. If the device
displays the highest signal level (full LED scale glows), adjust the sensitivity by clicking the touch panel. Repeat
