ALIGNMENT AND ADJUSTMENT
The alignment is comprised of two phases: the first is comprised of an optical alignment; the second
is comprised of an optimizing phase for the receiver.
Optical alignment:
Transmitter
This alignment consists of lining up the axis of the transmitter and receiver modules.
This basic alignment adjustment is performed for each module by using the integrated sighting
system and begins with the transmitter modules.
Description of the cell viewfinder:
1. Place the eye in front of the cell along an oblique
line of sight at a distance of about 5 cm as shown
in the accompanying figure.
2. Aiming consists in viewing the image of the opposite
module in the internal mirror using the opening on
the side of the cell.
3. Aiming is performed by rotating the sight
horizontally by directly manipulating the cell
fork + or - 90° , and by vertically rotating the
sight by manipulating the knobs + or - 10° .
Optimization of alignment:
Switch 1 and 2 to ON on TX and RX columns in order
•
to enter alignment mode.
Work on the cell to find sound frequency and quickest
LED blinking.
