FIRST TIME INSTALLATION
Type of motor
• Select SATSCAN if it is a Nokia SatScan motor.
• Select DiSEqC in case the motor you use is controlled by
DiSEqC commands.
LNB type
• Select Universal, one of the fixed frequencies or enter the LNB
frequency with the numeric buttons on the remote control.
LNB offset voltage
If the cable down from the antenna is very long, the voltage at
the LNB could be too low to change the polarization. You can in-
crease the voltage to the LNB by 0,5 Volt.
Satellite
Select Astra if you have a SatScan motor and Hotbird if you have
a DiSEqC motor.
Predefined channel
Select the predefined channel that will give the best Signal qual-
ity (SNR) bar indication. Within a few seconds you will get picture
from the channel in the background.
Adjust motor
• If necessary, fine tune the motor with the buttons on the
remote control.
As you now have a picture in the background, it is time to per-
form a Channel search procedure.
• Press OK......
....and you will get the Channel search menu.
The most common is to start from the “Automatic search” line.
(You can always make a Manual or Advanced Search later on.)
• Select the satellite you want to use on the Automatic Search
line, for example Astra.
• Press OK......
.......and you get the Antenna adjustment menu.
• If necessary, adjust the motor until the Signal strength (AGC)
and the Signal quality (SNR) are optimal. Please note, that this
will only affect the present satellite position.
Adjust motor for Astra/Hotbird
To continue the installation you now have to determine
the angle to Astra 1/Hotbird. The motor and the antenna
must be adjusted towards the Astra 1 satellites on 19.2
°
East (Hotbird satellites on 13
°
East) as this is the refer-
ence setting. All other preprogrammed satellite positions
are oriented relative to Astra 1/Hotbird.
You also have to mount the antenna at a proper place
outdoors.
How to do all this, please read the separate fitting in-
structions for the SatScan or DiSEqC positioner.
