unit is operating. The pendant includes a belt clip and
a battery. The pendant can also be mounted for fixed
position signaling, adapting to a wide range of
installations.
With the superior range and reliability offered by the

Wireless 900 MHz Band
The Inovonics EchoStream platform sends redundant
information on several multi-frequency channels within
the FCC Part 15 900 MHz band, providing superior
range and reliability. In comparison, systems that use a
single frequency technology can only send information
on one narrow band channel. Any interference within
the band can cause missed signals. With wireless
registration, it is easy to add this technology to any
application.
