MAIN MENU
System Information
If you have to contact your service provider or a service center,
they might ask for information available from this menu. There-
fore, it is important that you first check the information in the
following menus.
Diagnostics
To find out the condition of certain parts of the Mediamaster, you
can run a diagnostic test.
The signal input (strength) is messured in Signal-to-Noice ratio
(S/N). During normal conditions a S/N level of 18 - 20 dB will be
enough to give good picture and sound reception. However, to
achive good reception also during bad weather, atmospheric dis-
turbances or other interferences in the transmission, the signal
strength should be higher, something like 25 dB or more.
System Information
This gives general information about which hardware and soft-
ware version your Mediamaster is running on.
Conditional Access
A menu will only be activated if you have inserted a valid
CA module with a Smartcard in the slot behind the front lid.
The picture to the right is only an example of how a CA menu
might look like. The menus might differ with different modules.
If more than one CA system is activated, select the one from
which you want information.
