Set up and tuning

Some iDTVs will guide you through the settings on-screen. For others you will have to use the on-screen set-up menu – this should be explained in the manual.

The first step is to tune in the channels. This may happen automatically when you first switch on or you may have to initiate it. Again the instruction manual will explain.

Tuning in may take a minute or two as it automatically scans, looking for channels. All being well, you should get about 50 TV channels and about 25 radio stations.

If you get significantly fewer then there are a couple of possible explanations. You may want to check your coverage with Freeview – it’s possible you may be getting only partial coverage. Or you might need to upgrade your aerial.

If you get significantly more than 50, it may mean that you are receiving signals from two different transmitters. You could find double entries listed on screen for some channels that you will need to delete. Others in your neighbourhood are likely to have the same problem.

Maybe get a local Registered Digital Installer (RDI), if one is available in your area, to adjust your aerial so the TV ignores the weaker channels in the future. The RDI scheme is new, so there are not yet many available. See the RDI website for listings.

Some iDTV manufacturers tell us they can or will be able to screen out these weaker channels automatically – see individual detailed test reports.

Make sure you keep the instruction manual for your iDTV in a safe place as you will need to re-adjust its settings when changes are made to the broadcast signals at switchover.
