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.

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.

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.

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.

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-toair 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-toair channels. Previous channels will be replaced on automatic search.
