H/V
This setting determines the channel polarisation: horizontal or vertical. The H/V POL
setting can be adjusted between horizontal and vertical. You don’t really need to know
what this means but the technically minded might be interested to know that when you
select vertical polarisation, the receiver sends 13 volts up the cable to the LNB on the
dish. When you select horizontal the receiver sends 17 volts. The LNB looks for the
appropriately polarised signal, reflected from the dish, according to the voltage it receives.
In standby, the receiver turns off the LNB voltage. You will not need to change this setting
for pre-programmed Astra channels but you may need to change it if you customise any
channels to receive broadcasts from another satellite.
AUDIO
The AUDIO setting can be adjusted from sound tracks 1 to 6. Some channels use several
sound tracks for different languages. For these channels, select the sound track with the
appropriate language. Some channels use two TV sound tracks together to produce left
and right stereo. Most channels also use some of the sound tracks for mono or stereo radio
channels. For instance, you will find BBC Radio 1 to 5 on satellite in MONO but, because
the SRX200 can not provide all of the available audio frequencies, you will not be able to
receive them all.
To select a channel for radio it is best to use channels 48 downwards, to avoid confusion.
Find out what satellite TV channel carries the radio that you like and tune the picture in.
Then press the [AUDIO] button to get the radio sound track and store it by pressing
[PRESET] twice.
FINE TUNE
This setting determines the fine tuning of ALL channels to match a particular LNB on the
dish.
You may need to adjust it if some channels seem slightly off-tune despite their frequencies
being displayed correctly in the menu (you will see either black "sparklies" or white ones
on the satellite picture).
To adjust it, remove the screws beneath the receiver and push the top cover back and
upwards. Reconnect the receiver and plug it into the mains power. DANGER! keep hands
away from the mains transformer and wires at the left side of the receiver.
Select the worst affected satellite channel.
Locate the tiny adjuster, near the front of the receiver, marked "OFFSET" and turn it
slowly with a suitable screwdriver until the sparklies disappear from the satellite picture.
