Level indicator alignment is needed after the optical alignment is completed through viewfinder.
7-3. Rough alignment by viewfinder
Be sure to adjust both the upper and lower mirrors.
While looking through the viewfinder on the left or right of the mirror, turn the dial to make alignment in such a way that
the other detector is at the center of the sights.

7-4. Adjustment with level indicator
Fast flicker
Slow flicker
After the rough alignment using the viewfinder, make sure that one or more
level indicator LEDs are illuminated or flickering for both the top and the
bottom levels. If not, make adjustment again with the viewfinder.
In the rough alignment mode, each
LED of the level indicator switches
from the flickering to the continuously
ON state as the level of light reception
becomes higher.
[1] Checking of illumination of the indicator
[2] Adjustment in the rough alignment mode
Make optical alignment until the level indicator LED at the “Good” position
is illuminated. At this time, the level indicator LEDs at the lower positions
remain illuminated. This condition is called the rough alignment mode.
Be sure to start rough alignment
with the upper mirror. Otherwise
the level indicator of the
Transmitter may not work.
Continuously ON
Note
Once the level indicator LED at the “Excel” position is illuminated, all of the
LEDs start flickering fast together, which indicates that the mode is switched
to the fine adjustment mode. The level indicator LEDs at the lower positions
do not remain illuminated in the fine adjustment mode.
[3] Switching to the fine adjustment mode
Depending on the accuracy of the rough alignment by viewfiner, the beam adjustment
may be started from fine adjustment mode without rough adjustment mode.
Note
It may not change to fine adjustment mode when the detector is used with maximum
distance.
[4] Adjustment in the fine adjustment mode
When the mode is switched to the fine adjustment mode, the level indicator LEDs start flickering and
the indication point falls.How far the indication point goes down depends on the situation. Finding
the peak position in this condition allows fine-tuning.When the level of the “Excel” level indicator LED
exceeds the flickering level in the fine adjustment mode, all of the LEDs start flickering together again
and the indication point falls automatically. Repeat this until the alignment peaks.
Note
In the fine adjustment mode, the indication point may not reach the “Excel” position. This
indicates fine adjustment condition above the “Excel” position, which means that it causes
no problem in operation.
