    _VIP-F608 Characteristics
    Function 1: Tape recording truncation
    (Recording equipment shield does not emit any sound when working) It can interfere with all tape recorders. The RN-502A tape recorder of Panasonic Japan is used in the test. The optimum interference distance is 6 meters, and the effect can reach 90% at 8 meters. The effect can reach 85% in 10 places and 75% in 12 meters. All that was recorded was noise.
    Function 2: Digital recording interference
    The test uses Korean R200 digital recording pen. The best interference distance is 1.5 meters. All the noise is recorded. The effect of 2.5 meters is reduced to 75%. Occasionally, the voice is heard, but the voice is not understood. When the distance of 3 meters is reduced to 30%, the recorded sound will be noisy, but it can be understood. The test result is better after adding the directional interview microphone. The sound recorded at the distance of 4 meters is full of noise. The intermittent speech sound can be heard at the distance of 6 meters. The effect is about 60%.
    Function 3: Wireless/wired eavesdropping interference
    The capacitive middlehead wireless eavesdropper used in the test has a frequency of 118MHZ and a transmission distance of 100 meters. The sound you hear is totally noise. You can't hear the voice you're talking about. It has been proved by test that as long as the capacitive pickup can interfere with the sound. Therefore, it is proved that both wired and wireless eavesdroppers can interfere to prevent eavesdroppers from hearing voices.
    Function 4: Radio camera recording interference
    The test uses a 1.2G 10MW wireless pinhole camera. Under the action of the jammer, the image does not change and the sound becomes noise. The optimum interference distance is 4 meters.
    Function 5: Interview Microphone Interference
    The test uses a special ultra-directional microphone for TV station. The optimum interference distance is 5 meters. The effect is worse at 8 meters, and the sound can be heard at 10 meters.
    Function 6: Remote Opening
    The remote control distance can reach 15 meters. Round key is to turn on the red indicator, elliptical key is to turn off the green indicator. The reaction time of the switch is about 3 seconds.
    Function 7: Electronic clock
    With electronic clock function, display hours and minutes, for example: 12:18 = 12:18
    _VIP-F608 Operation
    1. The appearance of VIP-F608 anti-eavesdropping recording truncator resembles a desktop clock. It is usually placed on the desk as an ornament. In order to prevent the other party from recording, press the remote control during the conversation.
    2. The VIP-F608 recording truncator is packed in a bag. It looks like a laptop computer from the outside. When you go out to talk with people without recording, you press the remote control switch and the other side records all the noise.
    3. When the recording screen is cut off for the first time, plug in the charger, fill the battery completely, and then continue to use.
