Introduction
Congratulations! You have purchased the finest sports radar system available.
The S ATS II Ka-band sports radar was designed to measure the speed
of a wide variety of objects such as vehicles, baseballs, tennis balls and just about
anything that moves.
The S ATS II radar sends out very high frequency radio waves and
measures the change in the frequency after it bounces off a moving object. This
is commonly referred to as Doppler Radar. This invisible radio wave is
extremely low power (about 1/100th of a watt) and is completely safe for close
and continuous operation.
The S ATS II is a true digital radar system. The ATS II converts the
reflected microwave signals into a digital stream of data. The gun’s own
computer then processes this data stream using sophisticated programming, to
interpret, filter, and measure the speeds. This technology is closely related to the
compact digital disc and modern personal computers. This type of radar system
has the potential to provide substantially superior performance and accuracy over
conventional radar systems.
The S ATS II is a directional radar. It can tell the difference between
targets moving toward it and targets moving away from it. Using this feature, it
can track and report pitch speeds and hit speeds at the same time or filter out
vehicles moving opposite from the direction of interest.
The S ATS II radar gun has the capability of recording speed trials in its
on-board memory. One use of this feature is recording a vehicle’s speed multiple
times per second during acceleration or deceleration. The sequence of speeds
can then be reviewed on the gun’s display. Or it can be uploaded to a PC-based
tool such as the S ATS II software program for more in-depth analysis at
a later time.
While the technology in the S ATS II is extremely advanced, its
operation is quite simple. You need only to press the ON/OFF key and pull the
trigger to begin measuring target speeds.
If you want to be a power user and try other features and settings, reading
through this manual will help you to take full advantage of the other features and
capabilities of the S ATS II.
Have fun!

4-RADARS in ONE
The S ATS II is actually four different radars in one – depending on its
target type setting:
1. A Baseball radar
2. A Carnival radar
3. A Car radar
4. A Tennis radar
Page 5 has a definition of the target types.
Unless you were allowed to order your S ATS II
different mode of operation, the radar will come with the factory default setting
of car mode.
If you want to select another mode, follow the instructions below.

Quick Start Instructions
The S ATS II has several features that allow the gun to work well in a
wide variety of applications. With some basic understanding, the gun is very
simple to operate
Basic Operation
Power is supplied from the rechargeable battery handle. If it is not already
attached to the radar body, do so by inserting the front tip of the handle into the
mating lip on the body, rotating the handle up until it is firmly seated and rotating
the thumb latch to engage in the slot in the back of the handle.
The battery handle is not shipped fully charged. Charge it for four hours before
initial use to ensure a good charge.
Turn the gun ON by pressing the ON/OFF key.
Squeeze the trigger to begin operating (transmitting).
.
Important Settings
The factory default settings configure the ATS II for measuring vehicle speeds.
If other modes of operation are desired, use the two blue keys on the keypad to
configure the radar. The MENU key navigates through the menu structure to
choose a menu item, and the SELECT key changes the setting for the chosen
item. Refer to the Radar Configuration section for details.
Turning the Transmitter ON and OFF
There are two ways to turn on the radar transmitter to begin operating:
Trigger Transmit: Pull the trigger to transmit.
Transmit Key: Press the silver TRANSMIT key to toggle the transmitter ON or
OFF.
NOTE:
* When the gun IS NOT transmitting, the
XMIT icon is off and the target type displays
in the message (upper left) window.
* When the gun IS transmitting, the XMIT
icon is on and the unit of measure displays
in the message window.

The Target Types
The S ATS II can be configured for four different target types as listed
below. The gun processes and displays targets differently depending on the
selected target type. Processing for short-lived targets like thrown or hit balls
must quickly pick a small target out of the surrounding environment. Processing
for vehicles assumes that the target will be present for a longer duration and
displays its changing speed over a longer period of time.
Car
Car mode, the factory default configuration, is used to measure the speed of cars,
planes, racers, snowmobiles, people, or any other moving object. The most
accurate readings are acquired when the vehicle is traveling directly toward or
away from the radar. Any angle between the vehicle’s path and the radar’s aim
results in lower readings, but the ATS II can be set in the OPTION MENU to
automatically compensate for the Cosine Angle error to display true object speed
(see Option Menu item 10 in the Radar Configuration section starting on page 9).
S ATS II Owner’s Manual
Baseball
When configured for baseball mode, the ATS II measures the peak (release)
speed and the live (roll-down) speed of a baseball pitch. It analyzes not only the
ball but also the pitcher’s motion to report the most accurate release speed. It
also measures the speed of a hit ball and can display all three speeds (release,
roll-down and hit) at the same time. The ideal location for monitoring baseball
speeds is on the straight line beginning at the pitcher, going through the catcher,
and continuing to the radar with a clear view of the pitched ball’s path.
Baseball mode for Cricket
Baseball mode can also be used to measure the bowled speed of cricket balls.
Some differences between baseball and cricket present speed measuring
challenges and require modified settings and operation:
the bowling pitch is in the middle of the playing field so the targeted ball is
further from the radar unit;
the bowler runs toward the batsman before releasing the ball so there is extra
motion to be filtered out before the ball is in flight; and
the bowled ball has a wider range of possible flight paths from lobs to direct
throws to bounces, so the radar beam is not always aligned with the ball’s path.
Refer to the Recommended Settings section for more details.

S ATS II Owner’s Manual
Carnival
The ATS II can be operated in carnival mode to report the speed of balls thrown
only a few feet at a backdrop target in a carnival booth setting. In this
application the radar is usually mounted on a side support for the booth, so there
is a large angle between the ball’s trajectory and the radar’s aim. The ATS II can
automatically adjust for the angle error to display true ball speed.
Carnival mode can also be used for other targets with very short flight durations
like bullets or BBs.
Tennis
Tennis mode is much like baseball mode in that the ATS II measures the peak
(serve) speed and the decelerating live speed of a served tennis ball. Since tennis
balls are served at a wide range of angles, a good compromise location to mount
and run the radar is at the middle of each end of the court. From this spot, many
serves travel directly toward or away from the radar down the center of the court,
and the most accurate speeds are reported. Speeds for those serves traveling at a
large Cosine Angle to the radar’s aim will be reported low because of the angle
error.

S ATS II Owner’s Manual
LCD Display Windows
MESSAGE
MAIN
UPPER
Different types of speeds display in these windows depending on the type of
target being monitored.
The Car target type is for vehicles that may be tracked for long periods of time.
In this case, the “live” speed of the vehicle is most important, so it shows in the
Main Window. When peak speed is enabled, the highest speed of the tracked
vehicle is captured in the Upper Window.
The Ball, Carnival and Tennis target types are for targets that appear only for a
short time. Since the peak speed of these targets is most important, it shows up
in the Main Window. The “live” speed of the target slowing down shows up in
the Upper Window. And, if enabled, the hit speed of the target moving in the
opposite direction displays in the Message Window.
The five alpha-numeric characters in the upper left corner
make up the Message Window. Messages showing
configuration or status such as MPH, KM/H, BALL, CAR,
LOCK… display here.
The four large digits in the lower right corner display the
main speed of interest. The arrows to the right of the speed
indicate the direction of the target’s motion. The up arrow
signifies an outbound target moving away from the radar,
and the down arrow signifies an inbound target moving
toward the radar.
The four smaller digits and arrows in the upper right corner
show a secondary speed and direction.
