INSTALLATION
Although your receiver will not lose its settings or
stored channels when switched off, you may wish
to re-install the receiver because you have moved
to a different area with different broadcast
frequencies, you wish to reinstate a channel
previously deleted from the channel list, or you want
to watch new channels which have started
broadcasting.
Press the [MENU] key to display the Main Menu
and using the [UP] or [DOWN] keys, highlight the
Installation line and press [OK] to display the
Installation Menu.
You can either perform a First Time Installation,
effectively resetting the receiver to its factory
setting condition, or just search for channels.
FIRST TIME INSTALLATION
To reset the receiver, highlight the First Time
Installation line in the menu and press [OK]. A
warning screen is displayed in case of accidental
operation.
Highlight the YES button with the [LEFT] or [RIGHT]
key and press [OK] to erase all the channels and
settings and switch the receiver to standby. You can
now start again as detailed in - PREPARATION -
Initial settings on page 8.
ADD CHANNELS
The receiver can search for channels automatically
(searching all the broadcast frequencies for free-to-
air channels) or manually (searching one specified
broadcast frequency only for any channels to be
found there).
To perform Automatic search, Select Automatic
Search with the [UP] or [DOWN] keys and press
[OK]. A warning message is displayed. This starts
the automatic tuning process and searchesthrough
all the available broadcast frequencies for free-to-
air channels. Previous channels will be replaced on
automatic search.
If, alternatively, from the search options menu the
Manual Search line is highlighted and [OK] pressed,
the manual search screen is displayed.
Highlight the YES button with the [LEFT] or [RIGHT]
key and press [OK] to start the automatic search.
This is for searching for digital channels on a single
broadcast frequency. The frequency channel
number (21-69) is entered in the box at the top left
of the screen and the received signal level and signal
quality can be observed on the two bar graphs at the
bottom. When [OK] is pressed, the receiver
searches that frequency and display a list of the
channels found. Before returning to the Installation
menu.
Hint
The bar graphs of signal quality and signal
level give a good indication of whether any
channels are likely to be found. If only the signal
level graph shows a high value then it is likely
that an analogue channel occupies that
broadcast frequency. If the signal quality bar is
high as well then it is a digital frequency and
digital channels will probably be found.
Again, channels which duplicate those already in the
channel list are ignored. However, the manual
channel search will find all channels on the broadcast
frequency.
When either search is finished, press the [MENU]
key to return to normal broadcast viewing, to watch
the new digital terrestrial television channels found.
