Background

Your Velocity Radar Gun uses digital technology to provide instantaneous speed measurements to +/-
one MPH (+/- two KPH) accuracy. The Velocity Radar Gun is a simple, point and shoot radar gun for all
kinds of velocity experiments. Safely measure the speed of a tennis ball 90 feet away and the velocity of
vehicles from up to 1500 feet away.
Set-Up

Battery Installation:

The Velocity Radar Gun operates on two C alkaline batteries. To install, remove the battery cover by
rotating the battery cap counterclockwise. Insert both batteries positive end first and replace cap by
depressing and rotating clockwise.

How to Use:

1. Turn "ON" by pressing the button underneath the LCD display.
2. Aim at the target and depress the TRIGGER. As a quick reference to accuracy, remember to keep
your targets direction of travel in a direct line with you and not perpendicular to you.
3. Turn "OFF" by pressing the button underneath the LCD Display for 3 seconds or until display
shuts off. The display will read 3,2,1, and then power off.
4. To change unit of measure from MPH to KPH and vice-versa, make sure the unit is "ON". Next,
pull the trigger and leave engaged and quickly press the button underneath the LCD display
(quick presses of the button underneath the LCD display will toggle between MPH and KPH). The
unit of measure will be displayed in the top right-hand corner of the LCD display. When you are
satisfied with the unit of measure, simply release the power and trigger buttons.
NOTE: The Velocity Radar Gun contains an automatic battery saving shut-off feature. After 10 minutes
of non-use, the speed gun will automatically shut off. If a battery symbol appears on the lower right-
hand corner of the display, the battery voltage is beginning to deteriorate meaning new batteries should
be inserted. Remove batteries if storing long-term.
