2. FUNCTIONAL OVERVIEW
Thank You for purchasing the EQ Link and EQ Reverse Link (EQ-R-Link)
system.
The EQ Wireless Communications system is a state of the art audio
communication device specifically designed for Aviation headset applications
in high noise environments.
The EQ wireless system is compact; it includes re-chargeable batteries and
microphone noise cancelling circuits for optimum listening pleasure. The
devices feature only the essential controls to ensure ease of operation.
Advanced configuration and operations can be accessed using the simple
voice menu controls.
The EQ Reverse-Link makes virtually any aviation headset EQ wireless
compatible, this enables users to enjoy their own headset with the new
wireless experience.
The development of the EQ Wireless Communications system represents a
significant breakthrough in the field of wireless communications. For the first
time, pilots have access to a product, which is affordable, yet offers a very high
grade of voice and noise performance and is very simple to use.
The technical specification of the EQ-Reverse Link system will enable reliable
communications up to distances of 10 meters, depending on conditions. In
addition, the EQ transceivers incorporates superior signal handling capability,
which ensures excellent reception even in the most crowded radio
environments. The EQ LINK-LR (long range) is also available to extend the
communications distance if required.
In short, this revolutionary new system incorporates the very latest in RF
design technology, making the EQ the most compact, versatile, high
performance Headset communications solution available in the commercial
market today suitable for high noise open and closed cockpit applications.
