Mechanical alignment by using a periscope
Electro-optical alignment
Align the parabolic mirrors of the transmitters until the LED lights on the receiver panel light up. This
also applies to the LED lights of the radio controoled module, which is optional.
The alignment of both mirrors (top and bottom) must be carried out separately. However, the operating
module switch MO of the transmitter and receiver mirrors must be aligned at the same time. Note that
corresponding mirrors must be adjusted for both transmitter and receiver.

Insert the periscope support into the top pair of mirrors of the
transmitter and, looking through the periscope, carefully
position the mirror so that you can see in its center the
corresponding mirror on the opposite pillar. Repeat for the
other mirrors of the transmitter and receiver. If there is a large
distance between the transmitter and receiver, use a
searchlight to improve.
