Getting Started - an introduction to the Ranger EZ
This step-by-step guide will help you get started using the Ranger EZ and show you how to operate it in all of its
different modes. Working through this tutorial will take less than an hour, and it will teach you everything that is
necessary to take full advantage of the Ranger's capabilities. It will take much less time for you to learn the
Ranger's functions with this tutorial than it will if you try to figure them out on your own.
This guide assumes that you are familiar with basic radar operation. It will also be beneficial if you have
experience operating other radar units.
We encourage the customer to copy these pages out and use them as a checklist for training. Checkboxes are
provided to keep track of your progress.
Install the Ranger EZ
Install the Ranger EZ unit in the vehicle in accordance with the instructions supplied with the radar’s
mounting brackets.
Connect the front antenna to the Front port on the counting unit using the supplied cable. Connect the rear
antenna (if present) to the Rear port on the counting unit using the supplied cable. Connect the Blue 15-pin
connector of the power/signal cable to the blue 15-pin port on the rear of the Ranger. Plug the cigar plug of
the power/signal cable into the vehicle. Connect the speedometer interface cord and other wires of the
power/signal cable to the vehicle as described elsewhere in this manual.
Care should be exercised to ensure that none of the radar components or cables are placed in the vehicle’s
airbag deployment zones. Otherwise, the radar may become detached during the explosive deployment of the
airbag and become a dangerous projectile that could seriously injure the occupants of the vehicle.
If you have any questions regarding the proper installation of the Ranger EZ, please contact MPH. If you
have any questions regarding the airbag deployment zone of your particular vehicle, we suggest that you
contact the vehicle’s manufacturer.
Turn the Ranger EZ on
Press and release the Power button on the readout unit. This will cause the Ranger EZ to power up and
perform a Power-On Self-Test. The radar will light up all of its display segments and then display
“RANGER” in its speed windows. The unit will then perform a 32 mph internal test (moving and stationary)
and will display “PAS” in the middle window upon completion of the test.
Perform a self test
Press the “Test” key, located approximately in the middle of the remote control. This causes the radar to
perform an internal test of the processing circuitry, very similar to the Power-Up Self-Test. First, the radar
will light up all of its display elements in a segment test. Next the radar will display “RANGER”. Finally,
the radar will test itself with two Doppler tones, first in stationary mode at 32 mph and then at 32/32 in
moving mode. You will also hear the Doppler audio associated with these test speeds. If all of the checks are
