ABOUT YOUR VOICEDUCER EAR MICROPHONE SYSTEM
The concept of speaking and hearing through the ear is not new, but
its application in the VOICEDUCER two-way communications device
achieves a high level of performance that creates a breakthrough in
remote voice communications. The ear microphone is unobtrusive to
the casual observer, making it ideal for security applications. The
miniature earpiece leaves the hands free and face unobstructed
when worn by rescue and hazard-protection personnel, who still
retain the ability for direct hearing and speaking. And its high speech
clarity under noisy environmental conditions makes it ideal for airport,
factory and military communications. For personnel required to wear
breathing apparatus, communications with protective masks are as
clear as communications without. The usefulness of this remarkable
device cannot be over emphasized.
The VOICEDUCER system combines advanced electronic circuitry
with rugged construction enhancing performance, strength, and
reliability, while reducing the unit's size and weight. The
advancements include:
• FM conformed circuitry
• Shielded cable which minimizes adverse RF interference
®
• Kevlar reinforced ear microphone cable
• Die-cast housing
The VOICEDUCER represents a viable alternative to a headset with
boom microphone or a hand-held speaker/microphone in those
situations where existing equipment is not up to the task. The
VOICEDUCER is a direct replacement for any conventional ear-
mounted microphone, throat microphone or skull microphone. Its
quality and versatility enable personnel to operate safely and
effectively under adverse conditions.
The VOICEDUCER Ear Microphone Systems provide the following
operating mode by choosing the interface module.
• The MDRMN4044 includes a Push-To-Talk (PTT) interface
module that operates PTT only.
• The MDRMN4045 includes a PTT/VOX interface module that
operates PTT or Voice Operated Transmit (VOX).
