Basic Adjustment of the Polarmount Aerial

Manual motor control with the remote control
After pressing the
¢
F
(
ßR
) button, you have 8 seconds for
manually controlling the motor with the
xc
buttons.
Pressing the
O
button stores the new aerial position in
memory.
The display indicates, for example:
Neutral adjustment
It is possible to connect in addition to the rotary aerial a fixed
aerial to your receiver. For example, the rotary system to
input A and an aerial which is permanently directed at the
Astra satellite to input B (see chapter "Connection Examples").
The position of the rotary system should not change when
switching to a programme position used with the fixed aerial.
Enter "0°" as position for the satellite whose programmes you
wish to receive by means of the fixed aerial. The display then
indicates "
--
" instead of a value for the satellite position. The
rotary system then will keep its orientation (position).
Adjustment Run
One of the outstanding features of your receiver is the precise
aerial run to the preset satellite positions.
If the receiver is inadvertently switched off during an aerial
run, the impulses from the idling aerial motor are no longer
counted, resulting in an erroneous positioning for all
satellites.
By means of an adjustment run which is automatically started
when switching the receiver on again, the aerial is first driven
to its east end stop for correcting the bad positioning, then
the aerial is exactly positioned to the previously selected
satellite.
An adjustment run might also be necessary for other rea-
sons, for example, if a position offset is caused by strong and
lasting external impulses.
To start the adjustment run, keep pressed the
¢
ʐ button
while switching on the unit. Automatic correction of the posi-
tion is effected as described above.
It is possible to abort an adjustment run by pressing the
¢
P/F button.

Adjust the optimum skew value as explained above, press the
¢
MODE
ɶɶ
button once again, and store the setting with the
¢
MEMORY button.
From this point on, all programme positions preset with verti-
cal polarization are automatically set to this optimum value.
As a number of satellites are not fixed exactly according to
the polarmount method, it may happen that certain program-
mes need an individual correction. To do this, use the SKEW
menu option and not
the SKEW ALL menu option.
To adjust the optimum skew value for the upper frequency
range (12.5GHz), it is necessary to search a further satellite
(e.g., Kopernikus) and to adjust a station with V2 respectively
H2 following the already explained adjustment method.
The skew values V2 and H2 have no influence on the values
of H1 and V1. The SKEW ALL function can be used again and
greatly facilitates programming.
Storing the Satellite Position in Memory
After having made the above explained adjustments, the posi-
tion of the Astra satellite should be stored in memory. For
this, press the
¢
ʐ button.
The display indicates, for example:
Then, press the
¢
MODE
ɶɶ
or
¢
MODE
ʺʺ
button.
The display indicates, for example:
Press the
¢
MEMORY button to conclude storing.
All programmes of the Astra satellite with the pulse number
indicated in the MAN menu option (manual aerial adjustment)
are now stored with the position 19° East.
Following this method, you can store all satellites from east
to west:
Select a programme position for the satellite concerned,
search the satellite using the MAN menu option, and optimize
the signal level in the LEV menu option (to get the signal
strength indication, press the
¢
ʐ button). Then call up the
satellite position menu function (press the
¢
MODE
ɶɶ
or
¢
MODE
ʺʺ
button) and store the setting by pressing the
¢
MEMORY button.
If the motor drive should inadvertently start running when
calling up the programme position of a satellite which is not
yet stored in memory, motor run can be stopped by pressing
