7. Install the Telescope Alignment Tool onto the
transmitter module by inserting the captive
thumbscrews into the threaded holes on the
faceplate. See Figure 18. Ensure that the telescope
is properly attached, that the eyepiece is accessible,
and that the thumbscrews are completely tightened.
8. Slowly adjust the transmitter module up/down as
required using the vertical adjustment bolts until the
telescope cross hairs are centered as close as
possible to dead center on the window of the
receiver module. Tighten the vertical alignment
locking nuts so that no movement will occur.
