Very great spy gadgets.
With the unit switched "OFF" you can use the unit as a normal hands free!The fun begins when you switch the caller "ON"!
1. Plug the connection jack into the phone, put the earpiece into your ear and turn the power "ON".
2. Choose the "Voice mode control" you require,(either "MALE" or "FEMALE") and make a call.
3. When the person you are calling answers start talking and they won't know who you are!! You will hear a slight echo so you can hear how your devious voice sounds!
4. You can change the "Voice mode control"during the call so that you can pretend to be two different people, "MALE" or "FEMALE" !
5. To end the call press the "LIFT/HANG-UP" button.
6. If someone calls you, you can go into "Voice mode control" and press the "LIFT/HANG-UP" button and fool the caller because they won't know it's you!
7. When you receive a call the lights on the unit will flash to alert you of the call.
