Welcome to Decatur Electronics, Inc.
Thank you for choosing this Decatur Electronics product—the SVR™,
an advanced surface velocity radar (SVR) device for measuring water
surface velocity. The SVR™ is extremely valuable for measuring water
surface velocity during high-velocity ows and ood conditions
where using contact measurement instruments poses a risk to safety.
The SVR™ incorporates many leading features such as cosine error
correction for the vertical and horizontal angle positions of the gun
to the target. The SVR™ also contains a congurable horizontal
cosine adjustment that may be used when the angle of the gun is not
parallel to the ow of the target.
If you are as pleased with its performance as we think you will be,
ask your Decatur sales representative about other Decatur products
including the Genesis™ line of radars, the Onsite™ line of speed
trailers, dollies, and pole signs and the Responder™ line of in-car
video systems.
Try any one of our products and see if you don't agree that it is the
best-in-class!

About This Manual
This manual contains valuable information to help you set up, use
and maintain your radar, so you can optimize its life and keep it at
peak performance. Please take a moment to read through it, and
keep it handy for future reference.
Note the following symbols in this manual:
Indicates a warning message about safety
precautions. Please read it carefully.
Indicates a helpful tip or precaution to note.

In addition, the SVR™ is also designed to operate at
7.2VDC from the internal batteries. Over voltage to the
power cables or incorrect batteries can cause damage.
WARNING
Do not put the radar gun in the water. This will
damage it. The SVR™ measures the water surface only
from outside the water.

3. Getting Started
3.1 Introduction
The SVR™ is a hand-held surface velocity radar (SVR™) gun specically
designed to measure the surface velocity of water—great for use in
streams and rivers. Features such as Recall allows you to review the
previous measurement. Other features are selectable through the
menu option.
The radar gun features a tilt sensor system, which internally
compensates for the cosine angle eect of the vertical (pitch-down)
angle of the gun to the target. It is not necessary to manually set the
tilt sensor.
3.2 Battery Charging
The SVR™ is designed to operate o of six (6) rechargeable Nickel-
Metal-Hydride batteries (or o the DC power cord). When you rst
receive your radar, the batteries will need to be charged for the rst
time before using. Once batteries have been charged if you do not
use the SVR™ for 3-4 weeks, you will want to recharge the batteries
before use in order to get the full run time. To charge batteries for the
rst time or to replace the batteries following steps 3.6 to 3.7.
3.3 Removing the Battery Holder
The battery holder is located inside the handle of the SVR™ and is
accessed by means of a sliding door. When rst received, the holder
should already have batteries installed, but if not then you will need
to remove the holder and loaded it with batteries. To remove the
battery holder slide the battery cover to the right until the battery
holder is released as shown in Figure 3.3. The door can be completely
removed from the slide.
