1.Open batterie door, install the batterie perfectly and push batterie door into batterie box gently. Put the earpiece into ear canal by holding the handle and the slight sound of current indicate working order.
2.Adjust the volume of drive equipment to reach satisfaction.
3.Set mobile phone to automatic return or vibration.
4.Put the inductive loop around your neck and connect the inductive loop to the drive equipments (mobile phone, radio) which are attached to or beneath users clothing. One transmits message with radio, the other wearing an earpiece and inductive loop who also has a radio can hear the message very clear. Because the inductive loop inducts the message from the radio to earpiece and then earpiece transpourms the electromagnetic inductive signal to audio signal to reach the wireless inception. Communication distances and radio power are the direct proportion. You can communicate with others freely once network exist when you use mobile phone
