2.3. Scanning for an Unused Channel
On one of your TV set, scan for 2 unused channels in a row.
Memorize your TV set on the highest Channel (ex: if 35 and 36 are unused, memorize your TV
set on 36).
Then programme the same channel number on MODUline Twin (36 for instance) as indicated in
§2.1.2
You should now receive the programmes of your video appliances on your TV set.
If the image on the channel of emission is not clear either, then proceed as stated in order to find
an unused channel for modulator 2.
You may then tune all your TV sets as indicated in § 2.2.
3. ADVICE FOR INSTALLATION
Tuning the Output Level of the Modulators on MODUline Twin :
It can be tuned between 60
to 75 dBµV approximately with 16 stages (0 to 9, then A, b, C, d, E, F are displayed), by pushing
on “1” (or ”2” for modulator 2) for 5 seconds and then simultaneously on “+” or “-” to increase or
reduce level.
If the images transmitted by MODUline Twin onto your TV sets are blurred, then you need to
increase the output level.
If the images of some of your Hertzian programmes are blurred, then you need to reduce the
output level.
No images on the Programme Transmitted by MODULine Twin :
If you receive no images
from MODUline Twin after tuning your TCV sets, then check the connections between your video
appliances (satellite, VCR etc...) and MODUline Twin, applying the connections scheme chosen.
Low Commutation:
It is possible to stop or to activate Low Commutation between the 2 scart
cables of MODULine Twin, as it can be useful or disturbing, depending on the installation
scheme chosen. For this, push on “+” to activate the connection and on”-” to desactivate it.
Antenna Amplifier:
If your installation already includes an amplifier, it is better to place it after
MODUline Twin.
Display:
If you do not program MODUline Twin, the display shows slow switching is set automa-
tically (see on the page 8).
