OPERATING
A. NORMAL:
NORMAL mode of operating sets by default after plug in.
B. SETTING
It's possible to set up the SETTING mode of operating by
pressing "-" and "+" buttons simultaneously. To switch off
and return to NORMAL mode, press "-" and "+" buttons
simultaneously once more.
Both the modes of operating, NORMAL and SETTING, allow to
select the output channel by pressing buttons "-" or "+" near
the display. To select the output channel refer to tables form 1
to 10, depending on the modulation and canalization used in the
country where the product will be installed.
To change the parameters in SETTING mode of operating there
are 7 menu:
1. TV standard settings:
a) after switching SETTING mode, indicator displays the current
TV standard (refer to tables form 1 to 10, depending on the
modulation and canalization used in the country where the
product will be installed);
b) to set the necessary TV standard, press button "+";
c) after having selected the TV standard desired, the output
channel of the modulator MOD90S is the first channel of
selected TV standard (refer to tables form 1 to 10, depending on
the modulation and canalization used in the country where the
product will be installed);
d) other settings remains unchanged.
2. Test pattern generator switch on:

MODE DE FONCTIONNEMENT
A.
NORMAL :
Réglage par défaut du mode NORMAL après avoir bran-
ché le modulateur à l'alimentation.
B.
PROGRAMMATION :
a) press "-" button;
b) it's possible to switch between OFF and ON by pressing
button "+", "no" test pattern generator OFF, "t5" test pattern
generator ON;
3. Fine tuning of video carrier frequency:
a) press button "-";
b) change the video carrier frequency by pressing button "+".
Then the displays shows numbers form 0 to 9 and from -9 to -1.
Each of these numbers correspond to a frequency shift (refer
to Table 11).
Numbers 9 and -9 correspond to the maximum frequency
shift, +2,25 MHz and -2,25 MHz respectively. The shift space
between two adjacent values is 0,25 MHz.
4. Carriers A/V ratio switching:
a) press button "-";
b) switch between 12 dB and 16 dB by pressing button "+".
5. Output signal switch off:
a) press button "-";
b) switch between RF ON and RF OFF by pressing button
"+":"on" - RF ON, "of" - RF OFF
6) Regulation of audio carrier deviation:
a) press button "-";
b) set up the deviation by pressing button "+", (refer to table 12).
7) STEREO/MONO settings:
a) press button "-";
b) select the STEREO or MONO mode of operating by pressing
button "+", ("A-" - mono, "A5" - stereo).
PROTECTION FROM UNAUTHORIZED ACCESS
To prevent unauthorized access press buttons "-" and "+"
simultaneously twice in 0,5 second. A writing "LO" appears on
the display and the controls are locked. To return to the normal
operation without protection, repeat the procedure above.
SOUND SUBCARRIER DEVIATION SETTING
The default setting of the sound subcarrier deviation is ± 50
kHz when the input signal level is 1 kHz / 775 mV in both the
audio inputs. The regulation of ± 6 dB audio signal input sets
up through a software. Refer to Table 12 for this kind of setting.
OUTPUT SIGNAL LEVEL ADJUSTMENT
By means of the screwdriver, use the trimmer near to the output
F connector in order to adjust the RF output signal level (see
Figure 1, position 5). The output level adjustment range is 0 ÷
-20 dB.
Il est possible de régler le mode de fonctionnement
PROGRAMMATION en appuyant simultanément sur
les touches "-" et "+". Pour revenir au mode NORMAL,
appuyer de nouveau sur les touches "-" et "+" simulta-
nément.
Dans les deux modes de fonctionnement, NORMAL et PRO-
GRAMMATION, le canal de sortie peut être sélectionné en
appuyant sur les touches "-" ou "+" à côté de l'écran. Pour le
choix du canal de sortie, se rapporter aux tableaux 1 à 10 en
fonction du type de modulation et de canalisation utilisée dans
le Pays où le produit est installé.
Pour modifier les réglages des paramètres en mode de fonc-
tionnement PROGRAMMATION, il y a 7 menus :
1. Réglages standard TV :
a) après être passés en mode PROGRAMMATION, l'écran
affiche le standard TV courant (se rapporter aux tableaux 1 à
10 en fonction du type de standard et de canalisation utilisée
dans le Pays où le produit est installé) ;
