Changing The Offset; Turning On/Off Power To The Lnb; Setting The Dish Type; Setting The Polariser Ty - Pace MSS100 Series Service Manual

Changing the offset
You cannot adjust the offset until you have pointed the
dish at the satellite and can see some programmes.
The receiver has been factory-preset for automatic offset
(AFC). For a fixed dish, AFC should give a good picture
with few or no speckles. You should not need to alter
this unless you are trying to receive a very weak signal
with a speckled picture.
For a steerable dish, we recommend that you switch off
AFC.
>> Press F to switch off the AFC.
>> Press < or to set the offset manually between -15
and +15 to give the best picture, with an even mix of
black and white speckles.
>> Press STORE to save.
>> If a non-IRD receiver also has a dish connected to
Input 2, select a programme being received at Input
2. Display the Input 2 Menu and change the offset as
described above.
Turning on/off the power to the LNB
The receiver should provide power to the LNB except in
certain communal dish installations (in which case the
LNB must not receive power from the receiver). If you
are connecting your receiver to a communal dish instal-
lation, consult the installer for advice on which setting
you should choose.
Setting What is powered
Off LNB never powered from the receiver
On power to the LNB from the receiver
(if "On" is set at both Input Menus,
power goes only to the LNB which is
receiving the current programme).
Setting the dish type
The Dish option allows you to inform the receiver that
you have connected a steerable dish or a fixed dish.
>> Press < or to set "Steerable" or "Fixed" as
appropriate.
When "Steerable" is selected, the Polariser option
appears in the Input Menu.
Setting the polariser type
If you have not attached a dish positioner to the re-
ceiver, or have attached a positioner that does not
contain polariser control circuitry, the factory setting of
"Volt" is correct. Do not change this setting.
If you have attached a dish positioner that contains
polariser control circuitry, you must change the setting at
the Polariser option.
>> Press < or ® to set Magn/Mech.
If you change the Polariser option you must check that
the LNB option has the correct setting.
LNBs that have an electromagnetic or mechanical
polariser, are an advantage for steerable dishes as they
allow you to make adjustments to give the best picture
for each programme.
