A spy voice recorder is very useful when you need to discreetly record any conversation either at a moment’s notice or planned in advance. These devices are designed to be extremely unassuming and practical, usually disguised as a variety of everyday objects. Packed with a concealed microphone, a voice-activated spy recorder simply starts recording whenever sound is detected. If there's someone speaking, it immediately terminates its standby mode and it tapes what's being said. In the recording condition, push the "turn on/off" button to "off" position or connect the recorder to the pc by usb interface, the white light will go off, it stops and saves the recording files automatically. Connect the recorder with the computer and open the folder "setudisktimea" under the disk directory. Then double click the program "setudisktime(9x).Exe" in the folder. After that, the time of the recorder will be in sync with your computer system time. Connect the usb interface to the computer. When the red light blinks, it means charging, when fully charged, the indicator light steady red. It can continue recording for about 20 hours once fully recharged.
