c. COFDM2 modulation menu
In the next main menu you can select the
parameter cell_id (cell identifi er) of the COFDM
modulation:
d. Output menu
The next main menu shows the frequency or
output channel, the output off set (only in channel
mode), the level control and the selection of
output spectrum inversion.
To change the frequency press the key
desired parameter fl ashes. This fi eld can be then be
changed by means of the keys and
In frequency mode you can select any output
frequency value between 177.5 - 226.5 MHz
(VHF) and 474 - 858 MHz (UHF). The decimal part
depends on the diff erence of frequency chosen
(see extended menu b). If you select a diff erence of
125 KHz the permitted values for the decimal part
are 0, 125, 250, 375, 500, 625, 750 and 875 KHz.
With a diff erence of 166 KHz the possible values
are 0, 166, 333, 500, 666 and 833 KHz.
The output level control permits values between
00 and 99.
The possible values for the output spectrum
inversion are "Norm. " (not inverted) and 'Inv. '
(spectrum inversion).
In channel mode it lets you select an output
channel from the table selected as well as the off set
regarding the channel's receiving point frequency.
The permitted off set values depend on the
frequency diff erence selected (see confi guration
menu):
• Steps of 125KHz: ±4 (-500, -375, -250, -125, 0 ,
125, 250, 375, 500 KHz)
• Steps of 166KHz: ±3 (-500, -333, -166, 0 , 166,
333, 500 KHz).

e. Service menu
This menu shows the list of transport stream
services selected. Each time the user selects a new
input transport, the unit performs a search for the
services.
During that process the unit will display the
following message, indicating the number of
services found:
Once the search is complete, it shows the list of
services with the following information:
The service order number as well as the total
number of services in the multiplex (in service
fi gure 2 of 8 available) are indicated, the statistics
(in the fi gure 18/25), the name of the service and
if the user has selected it for removal in the output
(OFF) unscrambling (DCY) or to move it to output
without changing (ON).
The meaning of the statistics is as follows: the fi rst
number indicates the percentage of the output
