    Mic-Lock FAQ:

    1. Does it work with iPhone lightning phones?-yes, simply use the lighting to 3.5mm audio adapter that Apple provided with the phone
    2. How do I know it is working? Go into to the native recording app or video app and hit record. Make a sound and be sure you can see it recording audio. Insert the Mic-Lock and audio recording will stop or be silent. No audio being recorded.
    3. How do I configure it as the default mic input device? This is only needed on a Laptop or Desktop (PC or  Mac). Go to settings and select it as the default mic input source.
    4. If a hacker breaks into my computer can they not just toggle the audio source to find alternatives? Malware, hackers and viruses use software robots to do their dirty work. If you have your Mic-Lock plugged there will be “no-activity” which will make the bot report nothing. If you feel you are being personally targeted on a PC or Mac simply remove the native drivers on your your internal mic inputs. Bots will not add drivers to your audio input configuration.
