1 - Ideal scenario
• Got into MENU /
Installation / Program Terrestrial
• On the
Search Type
line, leave
Auto
• On the
Active Antenna
line, leave
No
• Go to
Start Search
and press OK
The terrestrial channels search window appears; it lists all the channels found. If no channel
is found, proceed to Scenario 2.
• Once the search is finished, press OK. All the channels found are automatically added to
the channels list (either at the end or the beginning of the list, depending on their logical
number).
2 - Favourable scenario
You know at least one channel number (between 21 and 69) broadcasting in your region.
• Go to MENU /
Installation / Program Terrestrial
• On the
Search Type
line, select
Manual
with
34
keys
• On the
Active Antenna
line, leave
No
• On the
Channel
line, select the channel number required with
34
keys
• You can now adjust the aerial in order to optimize the
Signal Level
and the
Signal Quality
.
Once the signal obtained is satisfactory, tighten the screws of the aerial.
• Go to
Start Search
and press OK
The terrestrial channels search window appears; it lists all the channels found.
• Once the search is finished, press OK. The channels found are automatically added to
the channels list (either at the end or the beginning of the list, depending on their logical
number).
• Now that your aerial is correctly orientated, you must scan all other channels. To do so, start
an automatic search, as explained in Scenario 1.
3 - Adverse scenario
You receive national channels in analogue mode and you have no idea which digital channels
are available to you.
Start an automatic search, as detailed in Scenario 1. It may identify some channels.
If you are certain that you can receive additional channels, but don’t know the corresponding
channel numbers, we suggest you proceed as follows:
Purchase a UHF aerial with a high gain (at least 15 dB) and connect it to the ANT input socket
of your Zapbox twin receiver. Orientate your new aerial in the same direction as the existing
one and launch an automatic search (see Scenario 1). If it locates channels that were not
found by the existing aerial, simply replace the old aerial with the new one. Otherwise, move
the aerial slightly, by an eighth of a turn, and start a new automatic search. Continue to rotate
the aerial by an eighth of a turn, launching a new automatic search each time. You should be
able to pick up a few channels. Switch to one of these channels, then press the
key twice
to display the signal level. Adjust the orientation of the aerial slightly, until you get a satisfactory
signal level and quality. Tighten the screws of the aerial securely and launch one more search.
Finally, link both aerials through a combiner. You will now be able to receive your analogue and
digital channels through the same cable.
