Troubleshooting
The channels are not adjusted to the programmed output level: Check that the programmed filter in the highest output chan-
nel has an adequate signal and level as this is taken as a reference for the adjustment of the selected output level.
The channels selected by BI/BIII (BIII)
terrestrial channel, if you need to amplify the signals in this band coming from satellite receivers you need to use the
"Broadband" input port. If you apply a sole channel in this input, its level will be adjusted to 5dB below the UHF channels level.
However, if with the same level, you apply a collection of equalised channels from satellite receivers, the unit will treat them
as though it is dealing with one channel with a greater level, reducing the adjusted level of the collection as regards the level
that we would have with one channel.
The channels in the broadband input are not equalised as regards the filters: The "broadband" input amplifies signals coming
from satellite receivers, the recommended level for this input is between 70 and 74 dBµV (for UHF channels) for these chan-
nels to be equalised with the rest of the adjusted channels. If the level applied is below the indicated range these channels will
have a lower level than the rest, and if the level is higher there will be disturbances due to the intermodulation of the channels.
A high/low level detected in an input or a filter: The adjustment process begins with the verification of the signal levels intro-

level is low when we do not apply the signal in these inputs will not affect the rest of the selected chan-
nels.
We must remember that the level indications in the FM (BI+FM)
control are a reference for the adjustment process, as this is the unit capable of balancing the channels where a level error
has been found so long as the input levels do not present large variations as regards the maximum specified range.
