Voiceducer with PTT Interface

Features & Benefits

Motorola original accessory. High quality and durability product.

Push-To-Talk Only Interface Module.

This PTT radio interface module can be used with any of the bone inductive
microphones. In addition it is possible to connect either an optional body
switch PTT or a finger PTT.

Ear Microphone System (EMS): This compact unit picks up the voice through bone
vibrations in the ear canal. This not only negates the need for an external microphone
but also minimises the pick up of background noise, making it ideal for use in high ambient noise environments.
The miniature earpiece leaves the hands free and face unobscured when worn by rescue and hazard
protection personnel, who still retain the ability for direct hearing and speaking. For personnel required to
wear breathing apparatus, communications with protective masks are as clear as communications without.
And its high speech clarity under noisy environments makes it ideal for high noise environments.
