3. INSTALLATION AND OPERATION
(e) When the SIG level has been maximised in one plane, make small adjustments in
the other plane until SIG has been maximised in this plane.
(f) Repeat steps (b) to (e) until the SIG level has been maximised in both planes.
At this point, SIG must be bigger than the initial TGT level and any adjustment
either side of the current alignment must result in a reduction in signal level.
If not, repeat steps (b) to (e) until these requirements have been met.
(g) Lock off the alignment by placing a hex (Allen) key in the pair of grub-screws
which control adjustment in a particular plane and simultaneously rotating them
inopposite directions.
(h) Repeat this for the other pair of grub-screws.
(i) Press Enter and the signal levels are checked.
With the SIG level is greater than the TGT level, the signal check should
pass and the screen should display the following message:
Signals OK
Notes:

Low Signal
Enter to Retry
2. If SIG is more than the TGT value the screen shows the bar graph screen again.
