Waterfall Feature Operation Manual
Introduction
The Waterfall Feature is available for the SDS100 and SDS200 scanners. It covers a
user-selectable span or band of the radio spectrum to show you graphically the radio
transmissions that are present. The Waterfall feature quickly shows you how active a
span or band of the spectrum is. When you see a transmission displayed, you can
navigate to it to listen to it.
Since all transmissions occurring in the selected span will display at the same time,
you'll be able to see possible relationships between transmissions. For example, you
might see simultaneous repeater transmissions on multiple frequencies or find a
repeater input frequency associated with the repeater output frequency. The strength of
signals will provide clues about the nature of the transmissions or how far or near the
transmitters are. Alternatively, they will tell you the relative strengths of transmitters.
These observations will enable you to gain a quick understanding of unfamiliar radio
systems or of a new location.
Installation
Go to Uniden.com and
 Register your scanner (if you haven't done so already).
 Download the latest version of Sentinel.
Use Sentinel to download the most current firmware for your scanner model.
Purchase a License Key for the Waterfall Feature from Uniden.com or from your
