About Signal Strength (AGC)
and Signal Quality (SNR)
The different signal indicators at the top of the menu provide in-
formation about two things:
AGC: The AGC, shown with a red bar, will indicate the average
strength of any incoming signal, digital as well as analogue.
SNR: When a programme from a satellite channel shows up on
the screen, the indicator bar will change from showing
AGC to showing SNR. The bar is now red, yellow and
green, and will indicate the signal quality from that specific
channel.
Antenna Adjustment and Signal Check
Pressing OK from the selected alternative in the previous menu
will display the Antenna Adjustment menu (shown to the right)
on the screen.
For each satellite, (e.g. NILESAT, HOTBIRD, ASIASAT, ARABSAT
or PANAMSAT), up to 4 different channels are preprogrammed
and shown in the menu. When you adjust the antenna, your
Mediamaster will use the marked channel to find signals from a
satellite. (You can select another channel with the buttons.)
1 Adjust the antenna towards the desired satellite until you have
a high value on the Signal Strength (AGC) *
)
indicator (the red
bar at the top of the menu.)
2 When the antenna is correctly positioned towards the satel-
lite and the signal strength is as good as possible, press OK.
If you have found a digital signal you should then normally get
a picture from the marked channel.
3 The bar at the top of the menu will now change to a red/yel-
low/green Signal Quality (SNR) *
)
indicator for that specific
channel.
If you do not get a picture, you may be tuned to an analogue sig-
nal source. Another reason could also be that the antenna is po-
sitioned towards the wrong satellite.
Press the BACK button and start from point 1 again.
The reason could also be that the marked channel is not trans-
mitting at the moment. If so, select one of the other prepro-
grammed channels in the “Signal Quality” menu with the
buttons.
When you have picture from a TV channel, press OK. The Media-
master automatically starts searching for and downloads chan-
nels from the satellite. Please refer to page 18.
(If you have a good indication in the signal quality menu, but no
picture from any of the channel alternatives, try proceeding with
the channel search anyway by pressing OK).
