You can check the position of the beam using a digital camera with infared lenses.
You can see the beam shining on the landmarks around the remote head from the
side of the transmitter, or until dusk you can see the line of the beam with your own
eyes.
From the remote side you can see the light of the beam behind the head with the
shadow of the head on a surface (for example on a wall), or if you see toward the
side of the transmitter, there you can see shining the beam on landmarks, and with
the growing and declining of the shining rounded plate, which is the beam, you can
follow its moving.

Repeat the beam alignment with each transmitters on both sides.
In every transmitter there are twoshipping screws against the
bigger moving of the tube. These screws allow only less movings
for the transmitters, so if you need bigger moving you have to
pick them out first.
Anyway, GeoDesy-FSO strongly recomends that you take all of
them out first…
9.3 Set the beam size
You can set the beam sizes of each transmitter separately. So do not swi tc on more
than one transmitter in the same time!
You can set the beam size turning the focusing
tube. First you have to loose the shipping
screws which are functioning as transmitter
fasteners, during shipment. Then you have to
loose the locking ring which fastens the
focusing tube. After that you can manipulate
with the beam size turning the tube. If you turn
it in clockwise direction the diameter of the
beam will increase, and in counter-clockwise direction the beam size will decrease.
After you set the beam size, do not forget to lock the locking ring and tight up the two
shipping screws, but be careful that the transmitter does not move out its position!
The provide the excellent operation you need the following beam sizes:
On 3000m distances the diameter of the beam should be 3meters!
On 3250m distances the diameter of the beam should be 3,25 meters!
On 3500m distances the diameter of the beam should be 3,50 meters!
On 3750m distances the diameter of the beam should be 3,75 meters!
On 4000m distances the diameter of the beam should be 4 meters!
You can measure your beam size using a digital camera with infraed lenses. With
this you can see the beam behind the head on a surface (for example on a wall) and
