WORKING MODE "CALIBRATION"
- In order to make a first rough alignement, use optical
view-finder, visualizing the centre of the concerned
reflector in the centre of the framed area. In order to move
orientation towards right, rotate the horizontal
adjuster clockwise, in order to move orientation
towards left, rotate the horizontal adjuster
counter-clockwise.
- To move orientation upwards rotate the vertical
adjuster counter-clockwise, to move it
downwards rotate the adjuster clockwise.
- Make the same with the Transmitter
- Before supplying the beam check
jumper S6 condition:
• keep it closed for 12V
• cut it for 24 V supplying
- Before supplying the beam units, check S6
jumper in both Receiver and Transmitter:
• cut jumper for distance from 5 to 35 meters.
• keep jumper closed for distance from 35 to 100 meters.
- Set properly dip switch 1 - 2 - 3 in the Transmitter according to
shown in chart on page 6
- At firs supplying, the beam is blocked for about 30 seconds. Wait before following step.
- At power up, the beam units remain inhibited for about 30 seconds. Wait for this delay before
proceeding to following step.
- Close S2 jumper in the Transmitter in order to get the beam units to Calibration mode.
• the green Led in the Receiver will remain on if the signal is received from Transmitter
• the display/Led module will visualize the recived signal
- During calibration process avoid the visualized value exceeding 7,1V (7 display - 1 led). Should
this occur, act on the trimmer RV1 to decrease the signal under the threshold.
- Adjust both Receiver and Transmitter until obtaining the max signal value on the display/Led
module in the Receiver.
- Act on Transmitter RV1 Trimmer until obtaining the value of 6,5 V on the display/led module (6
display and 5 Leds on) of the Receiver.
- Considering that the longer is the range, the longer is the beam, it is necessary to set the sensitivity
level in the Receiver according to the distance between Receiver and Transmitter, following the
rules below:

At the end of calibration, open jumper S2 in the Transmitter and take away the BF Test small
glasses before inserting the covers.
The 4 fixing screws of the covers can be "hidden" by using the screw-covers given within, just for
esthaetical reasons.
