Principals of operation:
The Sports Radar Gun is a microprocessor based computing device that uses a low power
doppler radar transceiver. The radar gun sends out a signal, which bounces off the object you are
tracking and is reflected back to the radar gun. A mixer provides the difference in the frequencies
of the original sent signal and the reflected signal that bounced off the object. From this difference
signal, which is proportional to the speed of the object, a microprocessor calculates speed and
displays it in miles per hour (MPH) or kilometers per hour (KM/H).
When the Radar gun is off
boresight of target, the
reading will be LESS than
actual ball speed by the
cosine of the ANGLE

Trigger Mode:
This mode of operation allows for a speed to be
taken at any given point. Example: you wish to register a baseball's
speed as it crosses home plate. Place the slide switch so it is in the
center position, under the TRIGGER line. As the ball is approaching,
squeeze the trigger (the display will blank) and when the new speed is
displayed, release the trigger. If no speed was recorded, the display will
show 000 when the trigger is released. In addition, when a speed is
recorded, you will hear a beep.

left position. This is the "hands free" mode of operation. The radar
gun can be affixed to the Sports Radar tripod (optional), or a
standard camera tripod (with ¼-20 mounting threads). Aim the
Radar Gun down the line of travel of the object you wish to register
the speed of. There is an internal delay between speed readings in
the continuous mode, and speeds can only be registered once every
3 seconds. This delay between readings ensures accuracy and
eliminates double readings from the same pitch. For example, if two
people are playing catch, it is necessary to wait at least three
seconds between pitches. Each time a new speed is recorded, you
will hear a beep, the display will blank, and the new speed will be
displayed.
Replacing Batteries:
To change batteries, Push the rear
sight in and lift the cover. Do not pull on the battery snap wires,
remove batteries by holding the battery snap cover. Snap new
batteries to battery snaps and place inside housing and
replace the cover. Take care not to pinch battery wires in
between battery cover and body of the case. Care needs to be
taken not to rip the wires out of the battery snap cover when
replacing the batteries, as this is not covered by the warranty.
DC JACK, External Power:
The
SR3600 Radar gun can be powered by an
external power supply to save battery life.
Sports Radar offers 2 products for connecting
to the DC power jack: the WA6VDC is a
plug in transformer that gets power from a
standard 110VAC household wall plug.
Radar Data Port:
The Data Port is
used EXCLUSIVELY to connect to Sports
Radar Radar’s adapters and displays. DO
NOT ATTEMPT TO CONNECT A
STANDARD CABLE TO THIS PORT,

Low Battery Indicator:
If the batteries in the SR3600
become low, the speed display will begin to flash. When this occurs
the pictorial, you can see that the ANGLE is a measure of how
far off line the boresight of the Radar gun is to the travel of the
target, the ANGLE is affected by how far to the side, and how
far
behind
(or in front of) the point where the speed reading is
taken. The more the angle, the lower the displayed speed will
be relative to the actual target speed. Visit our website at
http://www.sportsradargun.com
for detailed Information
regarding the cosine error.
Targets
:
the size, shape and material of the target object
determine the range or distance you can be from the object
and still get a reading. Large solid objects can be read over
500 feet away. Smaller objects such as a baseball or tennis
ball have a range of 30 to 60 feet. The Radar gun can register
speeds from 8 to over 200 MPH, however the Radar gun is
optimized for registering speeds from 15 to 100MPH (24 to
161 Km/H), the distance from the object you are measuring will
be the greatest in this range of speeds.
Displayed units, MPH or Km/H:
The units you want
to display, Miles Per Hour (MPH) or Kilometers Per Hour
(Km/H) are selected when the gun is turned on. If you want the
display in Miles per hour, hold the trigger in and turn the gun
on (either trigger mode or continuous mode) and the MPH
indicator will come on. Turning the gun on without depressing
the trigger will activate the Km/H mode.
Operating your radar gun:
To register a target's speed, the target
must be in the line of the boresight of the radar gun, and can either be going
away, or coming toward the radar gun. The BEST PERFORMANCE, or the
most accurate readings, are given when the boresight of the radar gun is in the
same line as the target travel. The angle between the line of the target and the
boresight of the gun is VERY important to get an ACCURATE reading. In
Continuous Mode:
This mode of operation
allows an individual to use the radar gun without
assistance from additional people. Place the slide
switch under the CONT (Continuous) Line in the far
the radar gun batteries need replaced. Battery life using two 9-volt alkaline batteries is
typically over 50 hours in the trigger mode, and 5 hours of continuous operation. To add to
the battery life, turn off the radar gun when not in use.
Stay clear of all roadways. This device is not intended to measure the speed of vehicles. Do not use this unit with the 110-volt
transformer in a wet or damp condition. This may cause electrical shock, which may cause death or permanent injury. To
prevent personal injury or death, maintain a safe distance from the objects you are measuring speeds of.
OR THE EQUIPMENT YOU ARE CONNECTING TO CAN
OCCUR. Complete details, cables and adapters for the DataPort
connection are provided with the remote display or accessories
purchased.
Ask your retailer, or visit our web site at

for information on displays and
adapters for the SR3600 RadarDataPort.
The AA12VDC is an automotive accessory outlet plug in power supply.
Ask
your retailer, or visit
http://www.sportsradargun.com
for information on
these two alternate power sources for the SR3600 Radar gun. The SR3600
jack will “sense” when the WA6VDC, or the AA12VDC is connected, and
will not use any battery power so there is no need to remove the batteries
when connecting a power supply, they automatically disconnect when the DC
jack is plugged in.
