Mounting the Rotator and Antenna
I
NDOOR
1. Temporarily connect the rotator unit and the con-
troller using the supplied connection cable.
2. Turn the SPEED control fully counter-clockwise,
and set the SELECT SWITCH on the rear panel to
the right ( ) position.

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." Verify
that the controller's pilot lights have become illumi-
nated.
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 0° (N:
North).
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 0° (straight up), 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 0°.
If the indicator needle is not pointing exactly to 0°,
go to the rear panel of the controller, and use a small
screwdriver to adjust the FULL SCALE ADJ po-
tentiometer (see below) so that the indicator needle
points exactly to 0°.
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 360° point.
If the OVERLAP LED does not light up at the 360°
position, the OVERLAP LED ADJ potentiometer

(on the rear panel of the controller) may be used to
align the illumination threshold to the 360° point.
10. Check to verify that rotation automatically stops at
approximately 90° (East; representing a total rota-
tion 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 90° (East).
12. Set the PRESET control to 0° (fully counter-clock-
wise), and press the START switch. The rotator
should rotate counter-clockwise, and stop exactly at
0°.
If not, go to the rear panel of the controller, and use
a small screwdriver to adjust the PRESET ADJ A
potentiometer so that the rotator stops at exactly 0°.
13. Set the PRESET control to 90° (fully clockwise),
and press the PRESET switch. The rotator should
rotate clockwise, and stop at exactly 450° (90°; East).
If not, go to the rear panel of the controller, use a
small screwdriver to adjust the PRESET ADJ B
potentiometer so that the rotator stops at exactly
450°.
14. Repeat steps 12 and 13 several times until the indi-
cator responds reliably to presetting small angles
when the rotator is near both ends of its range.
15. Set the SELECT SWITCH on the rear panel to the
left (
