At your Dish Positioner, the display will show the number you entered at the
receiver Tuning Menu, followed by the message "not set". The position number
will then be redisplayed. Using the Dish Positioner handset, press the EAST or
WEST keys as required, to move the satellite dish until you receive a good signal.
Note that the 3-digit position will be shown on the front panel display.
¢
You may want to change the signal polarity, by means of the H/V key. This can
improve the picture quality a great deal. (You can set up your position numbers
to pull in H (Horizontal) or V (Vertical) programmes. See the adjacent box on
Polarity Types.)
«
Press STORE to store the dish position and polarity type (H or V).
¢
The position number will flash on the display. Use the A or W keys or the P-- key
to change this number, if required. (It should correspond to the number you
entered at the SATELLITE option in the receiver Tuning Menu.)
¢«
Press STORE again. The 3-digit position will be shown on the display. You can
then press NORM to return the Positioner to normal mode.
From now on, whenever you tune into this programme on your satellite TV receiver,
the MSP995 will move the dish round to the position you have established.
Your position numbers can be set up so that they cover either all Horizontal (H) or all
Vertical (V) transmissions from any one particular satellite. For example, position 1
could be assigned to cover all Horizontally-polarised
programmes
from Astra.
Position 2 could be set up to cover all Vertically-polarised programmes from Astra.
Then, at the receiver Tuning
Menu,
for each
Astra programme
you alter the
SATELLITE option to 1 or 2, depending on whether the programme is H (Horizontal)
or V (Vertical). Remember to press the STORE key to store any changes you make.
Using the Receiver Scanning Mode
As an alternative to entering the frequency of a desired programme straight into the
receiver Tuning menu, you may want to use the Frequency scan mode provided on
your Pace satellite receiver. This allows you to step through the frequency range and
pick out the channels you are interested in.
Follow the instructions given in the receiver's user manual.
Changing Polarity Values
An important feature of the MSP995 is the capability to assign polarisation information
to each satellite position you set up. You can apply a polarity type — Horizontal (H)
or Vertical (V) — and a polarity value for each satellite you are receiving from. Once
programmed in, the MSP995 will apply these values when you choose a programme
at your satellite TV receiver.
You will have seen above how you can set up two position numbers for a single
satellite. One for Vertically-polarised programmes and one for Horizontally-polarised
programmes.
With the MSP995 you can also allocate a polarity value (or skew value) to satellite
position numbers. Adjusting the polarity value allows you to precisely line up the
polarisation of your dish aerial with the polarisation of the signals coming from the
satellite. This is necessary because signals from different satellites arrive at the
receiving site at different angles. Also, your polariser may not be aligned exactly —
adjusting the polarity value can improve matters. So, you can fine tune your system
for optimum reception on a satellite-to-satellite basis by changing the polarity values.
To adjust the polarity settings for a given satellite:-
*
At your receiver, select a programme which comes from that particular satellite.
The dish will track to the position you have set up previously and the front panel
display will show the position number.
*
Putthe Positioner into program mode (MODE then 1) and press the POL key on
the Positioner handset.
*
The front panel display will show a polarity type (hor or ver) and then the polarity
value (skew) for this position. (See box right).
*
If necessary, flip the polarity using the H/V key. Use A or ¥ to alter the number
until you get the clearest picture (with the least sparklies) you can.
*
You may want to slightly alter the dish position. Use the EAST or WEST key, as
required. (You can still use the A or W keys to alter the skew value.).
*
STORE this polarity setting against the flashing position number. Then press
STORE again and the display will show the 3-digit position of the satellite.
*
Pressing the NORM key will take you back into normal mode.
> POLARITY TYPES
We advise that you set up two
position numbers for each single
satellite. Your MSP995 allows you
to configure positions specifically
to receive either H (Horizontal) or V
(Vertical) programmes.
Use the H/V key toassign a polarity
type (H or V) when setting up your
positions.
Your position numbers might look
something like this:-
Pos. No.
Satellite
Astra (H)
Astra (V)
Eutelsat (H)
Eutelsat (V)
Intelsat (H)
Intelsat (V)
> POLARITY VALUES
The MSP995 comes supplied with
factory-set skew values (polarity
values) for reception of Horizon-
tally- (H) and Vertically-polarised
(V) transmissions.
But you might
want to change these values to
"fine tune" your satellite positions
for best reception.
The polarity type (h or v) is dis-
played, along with a 2-digit number
.(the polarity value) between 00 and
63. (For example, "N23" or "v14").
Change the number as required —
the scale stops when you reach 00
or 63.
Note that this skew value now be-
comes the new default value for
that particular polarity type — all
new positions you set up will have
this value assigned to them initially.
