To change the frequency press the key until the

changed by means of the keys and .
In frequency mode you can select any output
frequency value between 45 - 862 MHz. The
decimal part depends on the difference of
frequency chosen (see extended menu b). If you
select a difference of 125 KHz the permitted values
for the decimal part are 0, 125, 250, 375, 500, 625,
750 and 875 KHz. With a difference 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 offset
regarding the channel’s receiving point frequency.
The permitted offset values depend on the
frequency difference selected (see configuration
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

The service order number as well as the total
number of services in the multiplex (in service
figure 2 of 8 available) are indicated, the statistics
(in the figure 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 first
number indicates the percentage of the output
