Troubleshooting
When the adjustment button is pressed the error message
The unit does not allow two single-channels to be programmed in the same RF output channel. If this message
appears, the unit will not begin the adjustment, so press the button
trol's
display the first incorrect channel will be indicated so that it is modified.
The channels are not adjusted to the programmed output level:
Check that the programmed single-channel in the highest output channel has an adequate signal and level as
this is taken as a reference for adjusting the selected output level.
The channels selected by BI/BIII are not regulated correctly:
The BI/BIII input's function is to amplify a broadcasted terrestrial channel, if we need to amplify signals in this
band coming from satellite receivers we must use the "Wideband" input port. If we apply a sole channel in this input its
level will be adjusted 5 dB below the level of the UHF channels. However if with the same level we apply a collection of
equalised channels coming from satellite receivers, the unit will treat them as though it is dealing with a sole channel
with a greater level, reducing the adjusted level of the collection as regards to what we would have with one channel.
The channels in the broadband input are not equalised as regards the programmable single-channels:
The "wideband" input deals in the amplification of signals coming from satellite receivers, the recommended level
for this input is between 65 and 70 dBµV (for UHF channels) for these channels 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 single-channel:
The adjustment process begins with the verification of the signal levels introduced in the FM, BI/III input and
finally with the verification of the programmed single-channels. The indication that the FM or BI/III level is low when we
do not apply the signal in these inputs will not affect the rest of the selected channels.
We must remember that the level indications in the FM, BI/III inputs and programmable single-channels that have
appeared in the remote 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.
