Mounting the Rotator and Antenna

NDOOR
1. Temporarily connect the control cable between the
rotator unit and the controller.
2. Set the SELECT SWITCH on the rear panel to the
right ( ) position.
ADJ. MODE
3. Check to be sure that the POWER switch on the
controller is set to "OFF," then plug the controller's
AC cable into your station's AC outlet.
4. Set the controller's POWER switch to "ON." The
pilot lamps on the controller should become illumi-
nated, and the meter needle on the controller may
rotate so as to align itself with the current position
of the rotator (remember the two units have not been
aligned with each other).
5. Press the LEFT (rotation) side of the seesaw switch,
and continue to hold it until the rotator reaches the
counter-clockwise position where it automatically
stops ("Left" represents counter-clockwise rotation
when the rotator is viewed from the top).
6. When the rotator has reached the left "stop" posi-
tion, release the LEFT switch, and check to see if
the controller's indicator needle is pointing to 180°
(S: South).
If the indicator needle is out of alignment, grasp the
edge of the bezel around the bearing window, turn it
10 ° counter-clockwise, and pull it off. Then, grasp
the needle at its center and pull it straight off, re-
place the needle to 180° (straight down), and replace
the bezel.
7. Just above the round connector jack on the rotator
unit, you will observe two raised calibration marks
(one each on the "rotating" bell and "fixed" base of
the rotator). These two marks should be directly
aligned with each other. If not, place a small piece
of masking tape on the rotating bell and the fixed

base of the rotator unit, and make a calibration mark
will be used to verify the amount of rotation in the
next step.
8. Press the RIGHT (rotation) side of the seesaw switch,
and continue rotating to the right until the calibra-
tion marks (from step 7) are again precisely aligned.
Now check the indicator needle, which should also
have rotated fully 360° so as to be pointing exactly
to 180°.
If the indicator needle is not pointing exactly to 180°,
go to the rear panel of the controller, and use a small
screwdriver to adjust the FULL SCALE ADJ po-
tentiometer (see the drawing to the right) so that the
indicator needle points exactly to 180°.
9. Press the RIGHT switch again, and continue rota-
tion to the right. You should observe the OVER-
LAP LED becoming illuminated as rotation passes
the 180° point.
If the OVERLAP LED does not light up at the 180°
position, the OVERLAP LED ADJ potentiometer
(on the rear panel of the controller) may be used to
align the illumination threshold to the 180° point.
10. Check to verify that rotation automatically stops at
approximately 270° (West; representing a total ro-
tation range of 450° from the original starting point).
11. Press the LEFT and RIGHT (rotation) switches a
few more times, verifying that rotation appears to
be normal. If so, press the LEFT or RIGHT (rota-
tion) switch to set the rotator to 270° (West).
12. Set the SELECT SWITCH on the rear panel to the
left ( OPERATION MODE
POWER switch "OFF."
13. This completes the ground-based testing of the ro-
tator and controller.
