Introduction and Equipment Precautions
Congratulations! You now have the world’s most advanced headlamp aiming
technology available to the U.S. automotive aftermarket. The Vision II Pro™
Image Processing Headlamp Aimer provides factory-precise analysis to the
automotive aftermarket. Precision laser positioning, high technology photometric
analysis and computer quick calculations make the Vision II Pro™ the most
accurate headlight aiming device available.
The versatility of the Vision II Pro™ system enables you to aim nearly any
headlamp on any make of vehicle throughout the world. Standard, auxiliary, fog,
rectangular, round, or aerodynamic VOL, VOR, HIGH, LOW headlamps can be
precisely aimed, regardless of size.
The precision accuracy of laser technology is used to determine the vehicle
centerline and optical center of the headlamps. Computer-image processing
technologies form the basis for the Vision II Pro™ System. It analyzes and
displays the light pattern as it would appear on the roadway at twenty-five feet
(25’) ahead of the vehicle. Upon positioning the headlamp, a digital translation of
the headlight beam is displayed on the screen, graphically illustrating the ideal
alignment position in inches or centimeters. While viewing the screen, you adjust
the headlamp adjustment screws to align the beam pattern cross-hairs with the
visual aim indicators.
The Vision II Pro™ will never become obsolete. It will always be on the leading
edge of technology. The system can be expanded when new aim patterns
develop.
This user manual should be read in its entirety before operating the Vision II
Pro™ System. If you have any questions, please contact an American Aimers
Representative for further information at 1-877-343-7703.
FOR YOUR SAFETY, READ AND FOLLOW ALL CAUTION AND WARNING
LABELS AFFIXED TO YOUR EQUIPMENT.

1.4 ALIGNMENT METHOD
There are two recommended methods to ensure the Vision II ProTM aimer is aligned with the
centerline of the vehicle.
The LASER ALIGNMENT method utilizes the on-board laser to align the Vision II ProTM unit
with the vehicle centerline. The LASER ALIGNMENT method is the most widely used method
and the Vision II ProTM is pre-set at the factory to this mode. The FIXED POSSITION method is
for permanently installed applications where the track is attached to floor and the perpendicular
alignment of the vehicle to the track is assured by the use of wheel stops and/or wheel guides.
IMPORTANT: Unless you have a fixed track and need to change the laser mode, please
proceed to Section 1.5 on the following page.
If you choose to change to the FIXED TRACK mode you can do so by following these steps:
1.) Press and hold in on Button 1 while turning the main power switch on. Keeping Button
1 pushed, the aimer will proceed to a calibration screen - wait approximately ten
seconds and release the button. The Select Language Screen will appear; select button
(5) Skip. The Select Track Style menu will appear; select button (3) Fixed. The
information will be saved. Note – If the screen does not appear, repeat the process

SECTION TWO
2.1 SET FLOOR SLOPE
Since few shop areas have the same floor slope, the
floor slope of each aiming bay must be individually
measured and entered. A model G2 split image transit
is provided to measure floor slope.
This function allows changing the floor slope for each
bay. To determine the floor slope of the aim bay area,
use the G2 split image transit and target provided.
Place the transit at the front wheel (either side) of the
vehicle (A) and place the target at the rear wheel (B) of
the same side. Looking through the viewing window on the top of the transit (C) turn the small
thumb screw knob (D) until the black lines on the target are in a straight line. Turn the level
indicator dial (E), on side of transit, until the bubble is centered (F). Floor slope reading is
indicated by level/indicator dial (E). A plus (+) reading indicates vehicle is nose high. Enter the
value measured by using the “Plus” button (Button 2) for a plus reading, or “Minus” button
(Button 3) for a minus (-) reading. Reading on level indicator dial should be rounded up to the
nearest (0.1) of degree. (See instruction sheet with transit for additional details). Press and hold
the appropriate button (Button 2 or Button 3) until the proper value is shown at the bottom of the
screen. When the proper value is displayed, press the “NEXT BAY” button, (Button 4), to enter
the floor slope values for other aiming bays, repeat the previous procedure for each bay. Press
the “FINISH” (Button 5) to exit bay setup and save new values.

areas which could affect the positioning of the vehicle or aimer.
Drive the vehicle to be checked into the aiming area, set the parking brake.
Vehicle preparation should include the following:
Remove ice or mud from under fenders.
See that no tire is noticeably deflated.
Check vehicle springs for sag or broken leaves.
See that there is no unusual load in the vehicle.
Check functioning of “level ride” control, if applicable.
Clean lamp lenses.
Check for bulb burn-out, proper beam-switching, and moisture condensation
inside headlamp assembly. If condensation present, replace lamp assembly.
Stabilize suspension by rocking vehicle sideways.
Although the Vision II ProTM Aimer can “aim” the headlamps of a vehicle with the motor idling, it
is recommended that the engine be turned off during the aiming process. The vehicle headlamps
must be on. Locate the horizontal and vertical adjustment screws. In most cases the hood will
need to be raised to access the adjustment screws.

SECTION FOUR
4.1 SELF TEST
This feature is a diagnostic routine initiated by the
computer at power up. The computer checks
various operation functions, active memory,
calibration, any installed options and video
system.
The Vision II Pro™ is designed so that once the
factory calibration has been performed the unit
cannot become “un-calibrated” unless the unit has
sustained physical damage. The calibration is
checked as a part of the power-up self test.
If a calibration problem is noted, the monitor will
display the error. Should the monitor display an
error message upon start-up, reference the
trouble-shooting guide, if corrective action does
not rectify the problem; contact an American
Aimers Customer Service Representative.
4.2 PRINTER OPTION
The optional printer provides hard copy
documentation of before measurements and after
aim alignment verification.
4.3 ALIGNMENT TRACK
An alignment track is provided with Vision II Pro™
to assure greater accuracy and repeatability.
When placed under the front set of wheels of
aimer it will roll straight and true over dirt and
cracks. (Recommended for best results).

Vision II ProTM Manual
Page 19 of 28
4.4 CALLIBRATION PROCESS
The Vision II ProTM has been calibrated at the
factory. However, it is recommended that you
verify calibration before using your headlight aimer
for the first time and on a monthly basis. There are
three things that get calibrated during this process
(1) Internal Digital Level (2) Vehicle Miss-
Alignment Sensor (3) Vehicle Centerline Laser. To
get started, from the Main Menu select the Options
button (5) then select the CAL button (4).
STEP 1
Using a 5/32” T-Handle or Allen wrench loosen the
set screw on the wheel cam. Adjust the cam until
the vertical bubble vial on the top of the aim head
is level, then tighten set screw.
STEP 2
Locate the calibration marks located on the back
of the LCD screen and rotate the bezel until the 2
marks are perfectly aligned as shown.
STEP 3
Rotate the laser knob on the side of the bezel and
verify the laser dot hits the 2 calibration targets on
the top of the aimer case as shown. If adjustment
is needed, you can adjust the set screws on the
side of the laser knob until the dot hits both
calibration targets.
