Details
The integrative inductive module is part of a communication system and is used in conjunction with an inductive receiver which is inserted into the ear. The inductive module is worn on the shoulder covertly under the clothing as near as possible to the inductive receiver. The connection between the inductive receiver and the inductive module is wireless.
Housing of the inductive module with ergonomical design contains omni-directional microphone with noise squelch， amplifier， and inductive coil. The inductive module has two cables， one with interphone， the other with cylinder PTT button (PTT=push to talk). It also has a removable clip with safety pin for wearing on or under the clothing.
Cylinder PTT
QDC PTTs are manufactured from only the highest-quality materials. Their simplicity for operation， ease o f repair and robustness combine to produce extremely ergonomic products.
