Basic Adjustment of the Polarmount Aerial
Adjust theoptimum skew value as explained above, press the ¢MODE 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 (12.5 GHz), 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 ¢ button.
The display indicates, for example:
TIMER o p ü +
I99 XMANX132 STEREO
SIGNAL IIIIIIIIIIIII
Then, press the ¢MODE or ¢MODE button. The display indicates, for example:
TIMER o p ü +
I99 EASTX19 ° STEREO
SIGNAL IIIIIIIIIIIII
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 ¢ button). Then call upthe satellite position menu function (press the ¢MODE or ¢MODE 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
Manual motor control with the remote control
After pressing the ¢F (ßR) button, you have 8 seconds for manually controlling the motor with the x c buttons. Pressing the O button stores the new aerial position in memory.
The display indicates, for example:
TIMER o p ü +
I99 XMANX132 STEREO
SIGNAL IIIIIIIIIIIII
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
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 ¢ 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.
