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 7. 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 SRD400 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, locate the tiny hole, near the front of the receiver, underneath. The adjuster
slot is recessed deep within this hole. Turn it slowly with a suitable screwdriver until the
sparklies disappear from the satellite picture.
Checking the receiver status
Press [RECALL] once. The channel frequency will appear on the display then disappear
after a few seconds to show the AUDIO selection (1 — 6) which will also then disappear.
Pressing [RECALL] has no effect on the settings but simply allows you to check them.
Using a D2Mac Decoder
The SRD400 can not be guaranteed to work with every D2Mac decoder on the market so
this is intended as a brief guide. Try to see it working with your SRD400 in the shop
before you buy the decoder.
