and the detector is large it is helpful to place a brightly col-
ored object on the wall near the reflector to aide in seeing
the reflector in the alignment mirror.
3. Once the reflector has been located, begin to adjust both
the horizontal and vertical alignment knobs so that the
reflector becomes centered in the alignment mirror. Take
care in this step. If the optics are incorrectly aligned in this
step, it will not be possible to proceed with the fine adjust-
ment step.
Step 2. Fine Adjustment
Refer to Figures 10 through 12 for this step.
In this step you will be fine-tuning the optics to the reflec-
tor. To provide feedback of the signal level coming from the
reflector the dual digital display readout will be used. Due
to the large distance range that the detector can operate
over it is necessary that the detector operate with many dif-
ferent settings of “electronic amplifier gain”. The detector
is capable of determining the appropriate gain setting and
then setting it itself via on-board processing algorithms.
There are no external gain settings on the detector that
must be set by the operator. Periodically throughout the
fine adjustment step the detector will need to re-adjust its
“electronic amplifier gain” setting. When this occurs it will
be indicated by the dual digital readout as “- -”. When this
occurs, cease any further adjustment until the display again
reads a number value.
1. Insure that neither you nor any other objects are in the line
of sight between the detector and the reflector.
2. Depress the Alignment switch once. Both the digital display
and the yellow LED should turn on indicating that align-
ment mode has been entered. The display should begin
reading “- -” signifying an electronic gain adjustment. After
a few moments the display will indicate a numeric value
near 20. If the display reads “Lo” then the detector is not
receiving enough light from the reflector. Go back and
repeat the course alignment step and verify that the proper
number of reflectors is used for the installed distance.
Note: The display will continue to read “Lo” until the detector
receives enough light from the reflector to continue with
the fine adjustment step.
Note: In alignment mode (indicated by the yellow LED and the
numeric display) the sensitivity select and test switches
are disabled.
3. With the display reading a numeric value, begin adjusting
the horizontal and vertical alignment knobs one at a time
in the direction that increases the numeric signal level on
the display. Continue adjusting each axis one at a time
going back and forth between them until a peak value is
indicated. If a value of 90 is achieved, the detector will re-
adjust the electronic gain once again. This will be indicated
by a “- -” reading on the display. When this happens halt any
further adjustment until the display again reads a numeric
value. This process may occur more than once during the
fine adjustment step.
Note: Each time the display reads a value of 90 or greater
the detector will reduce the electronic gain. Each time
the display reads a value of 10 or less the detector will
increase the electronic gain.
4. Once satisfied that it is not possible to achieve a higher
reading on the display depress the alignment switch to
complete the fine adjustment step. The digital display read-
out will turn “OFF” and the yellow LED will remain “ON”.
Note: It may not be possible to achieve a value near 90 on the
display during the last adjustment iteration. The final
value of the display will not likely be near 90. This is nor-
mal. It is due to the detector reducing its electronic gain
each time a value of 90 is achieved. When this occurs the
detector resumes with less electronic gain than previ-
ously when 90 was achieved. Less gain makes it more
difficult to achieve higher values. Final values anywhere
between 20 and 90 are acceptable if no further increase
can be achieved.
Note: The alignment procedure is not complete yet.
At this time it is possible to set the sensitivity of the detec-
tor using the sensitivity switch and digital display. See the
Sensitivity Selection section of this manual for further details.
Step 3. Final Gain Adjustment
Refer to Figure 13 for this step.
In this step, the detector will electronically adjust its inter-
nal gain one final time. It is necessary to complete this
step with the outer housing installed since the housing will
change the amount of light received from the reflector.
1. Install the outer housing of the detector. The housing is
installed by tightening four screws, one in each corner of
the housing. The screws are captivated in the plastic of the
housing and cannot fall out during assembly.
Note: The housing contains a gasket seal that protects the
detector circuitry from corrosion and moisture sources.
To insure that the gasket seal performs correctly it is
necessary to fully tighten all four of the screws that hold
the outer housing in place.
