Setting the RF output channel
The RF Output screen lets you select the RF output channel for your box.
The factory preset RF output channel is channel 38. If channel 38 is not compatible with
your TV or VCR, for example if it is already being used as your VCR’s output channel,
or for a terrestrial channel, you may find you cannot tune your equipment to your box
because of interference.
You can therefore use this setting to enter a different number. You may find this easier if
you disconnect your external antenna and/or your VCR from your system while you make
the changes, but if you do so, make sure you follow all the safety advice on pages 7 to 13.
You will then need to tune any equipment that is connected to your box via an RF lead to
this new channel number - see the section on RF tuning on page 15.
RF channels may also be known as UHF channels.
To change the RF output channel:
1. From the Installation Setup menu, highlight ‘RF Output’, and then press OK .
The RF Outlets screen displays:
