Multi-detector 1MHz-6500MHz Signal Detector with Probe Laser/Radio Signals Signal Detector for Spy Camera VS307  multi-detector Product Description :  This product uses active laser scanning and passive wireless method of combining the sweep can be accurately identified : eavesdropping devices , Telephone eavesdropping , digital eavesdropping , tracking , vechicle eavesdropping , wireless pinhole cameras , wired cameras ,  electrical appliances and other sources ...... Can effectively prevent eavesdropping , vediotaping , fraud , protect personal privacy data and information confidential .  Founctions as follows : 1),with a uto-detection function , the host to carry , when the live enviroment of eavesdropping devices , pinhole cameras ,  Casino gambling fraud , ect ...the host will be in your auto-body vibration prompts risk .  2),with a signal strength indicator lights that can quickly find the signal at source .  3),adjust potentiometer adjustable sensitivity . ( creater sensitivity to widen the scope of or reduce the sensitivity to detect reduced Detetion range ) quickly indentify the waves at source .  4),detection mode :1.Laser detection , 2. Vibration (Mute)detection , 3. Beep detection , 4 LED display detection . 5 . Headset  5),low-voltage prompts , built -in rechargeable battery .  Laser Detection :Windows host can be seen throught the eyes of all within sight of the camera facing the camera .  Wireless sweep : frequency detection range ( 1NHz -6.5 GHz )  Instruction for use :  A:detection of camera lens 1),turn the power switch , power indicator light . (blue hair ). 2),click the laser switch , instruments back 6 LED light started flashing .   3),up and down and move around the instruments , laser scanning of the surrounding environment , eye observation of the host window . If the front of a camera lens , you will find a very strong bright spot in the flicker .  4),if a continuous hold switch , LED flashes every 2 seconds , the frequency would be faster a class .  5),and then click the switch to turn off the laser scanning .  Instruction for use :  A: detection of camera lens 1),turn the power switch , power indicator light . (blue hair ). 2),click the laser switch , instruments back 6 LED light started flashing .   3),up and down and move around the instruments , laser scanning of the surrounding environment , eye observation of the host window . If the front of a camera lens , you will find a very strong bright spot in the flicker .  4),if a continuous hold switch , LED flashes every 2 seconds , the frequency would be faster a class .  5),and then click the switch to turn off the laser scanning .  B：detection of radio waves ( wireless camera /listening device , ect . )  sound detection : 1),turn the power switch to the middle position , power indicator light (blue hair ). 2),move around , if the flashing red light , there are audio cues that have emission source .  The signal became stronger when 4 LED light at the same time , sound , great changes will become faster .  3),pulled out the antenna , adjust potentiometer to the maxium , can expand your search .  4),and gradually shorten the antenna , adjustment potentiometer in order to reduce the detection range , can eventually find the emission source . 5),insert the headset can also be used .  silence detection ( vibration detection ) :  1)Will be pushed to the top of the power switch , power indicator , light (blue hair ). 2),there is the signal , only a flashing light and vibration .  3),other actions with the  C: When Watches    This instrument in particular to increase this feature , for the profeesionals is very important .  D: Battery low Tips  When the built -in battery voltage is low , the first four panel status indicator will stop flashing .  5 ) , In order to avoid interference when the phone is near the phone or other wireless launchers work , should be suspended probe .  Applicable to the crowd : 1.
