wiring the plug
If your receiver is fitted with a non-rewireable plug and you need to change the fuse, you
will need to refit the fuse cover. If you lose or damage the fuse cover, do not use the plug
until you have replaced the cover with a new one. You can get one from us. Make sure
you replace the fuse cover with one which is the same colour as the markings on the fuse.
If you have to change the plug because it is not suitable for your socket or it is damaged,
cut off the plug and fit another one following the wiring instructions below. Please throw
away the plug you have removed, as insertion into a mains socket could cause injury.
For your own safety, read the following instructions carefully before attempting to connect
this unit to the mains.
WIRING INSTRUCTIONS
Your receiver is external power supply
unit designed to operate on 230 to 240V,
50Hz current only.
Connecting it to another power source
may damage the receiver.
The stb input : 6 V DC
WARNING
To prevent electric shocks, remove the
plug from the mains socket before you
take off its cover.
IMPORTANT
The colours of the wires in the mains lead
from your receiver may not be the same
as the coloured markings identifying the
terminals in your plug. So please follow
these instructions.
Connect the blue wire to the terminal
marked with the letter N or coloured black.
Connect the brown wire to the terminal
marked with the letter L or coloured red.
Do not connect any wire to the other
terminal on the plug.
If you use a 13 Amp (BS1363) plug, you
will need a 5 Amp fuse.
If you use any other type of plug, you will
also need a 5 Amp fuse either in the plug
or on the distribution board.

CONNECTIONS
Place your GDB4 receiver on a firm, level surface with at least a 10cm gap around all
sides of the case and in a position convenient for connection to your television, a mains
power outlet and a TV aerial wall outlet (or the 'flying lead' from your TV aerial, as
appropriate).
Please refer to the safety section in Appendix A.
Turn off your television at the mains and disconnect the lead going to the aerial wall outlet
(or the flying aerial lead) and connect this to the ANT IN socket on the rear of the receiver.
Connect the aerial cable supplied from the TV OUT socket on the receiver to the TV set's
aerial socket.
Connect the TV SCART socket on the rear of the receiver to a suitable SCART socket on
your television. There may be more than one SCART socket on your television and, if
unsure which to use, you should refer to its manual for guidance.

SWITCHING ON
Turn on your TV set and select the SCART input (with the AV key, or similar, on the
television remote control). Turn on the mains supply to the GDB4 receiver (the indicator
on the front of the receiver will glow red) and press the [STANDBY] key on the GDB4
remote control handset. The indicator light will glow green and the receiver's menu will be
seen on the TV screen.
If you do not see the receiver's menu on the television screen, refer to the Troubleshooting
Guide in Appendix E.
TUNING IN
Because this is the first time that the receiver has been used, there are no channels
stored in the receiver's memory and the First Time Installation menu is displayed on
the screen.
FIRST TIME INSTALLATIONFIRST TIME INSTALLATION
Please choose TV Type using keys
Press to start installation
SELECT
NORMAL 4:3
First you should select the type of TV set you have connected to the GDB4 receiver.
Press the [LEFT] or [RIGHT] keys on the remote control handset to switch the indicator
on the screen to show either 16:9, if you have a 16:9 or 'widescreen' TV, or to 4:3 if you
have a standard TV set. Then press [SELECT] to start the installation process.
The next menu will ask if you want to tune in the digital terrestrial television channels.
Using the [LEFT] or [RIGHT] keys on the
remote control, make sure that the YES
button is highlighted in yellow, and press
the [SELECT] key to start the automatic
search.
The GDB4 receiver will automatically
tune to the UHF transmission channels
21 to 68 looking for digital terrestrial TV
broadcasts and displaying the names of
channels found. This process will take
about five minutes.
Do you want to start automatic search?
YesNo
8
preparation
When the search is finished, the first channel of the channel list and the information
banner is displayed you can now watch digital terrestrial television, selecting the channel
you require as described in the next section.
1
HINT
Depending on the reception conditions
in your particular area, you may find that
the list of channels found includes one
or more repeated names. This is because
the receiver may detect and store some
channels, including those it cannot
receive clearly, from adjacent areas
alongside the strong channels from a
transmitter nearby. This is not a problem
and the weaker channels can be deleted
from the receiver later, as described in
Section 3 - ADVANCED OPERATION Editing the channel list.
When you have finished watching digital terrestrial TV, you may wish to switch the receiver
to standby to save power - although the GDB4 receiver can remain powered up
continuously, even when the television is turned off, without harm to the television or itself.
The receiver is returned to standby by pressing the [STANDBY] key on the remote control
handset.
If no digital terrestrial television
broadcasts are found the receiver will
display a message:
NO SIGNALNO SIGNAL
You should then refer to the
Troubleshooter Guide in Appendix E
to establish the cause of the problem.
Hint
In standby, the GDB4 receiver still
consumes power and thereby contributes
to air and water pollution and the
exhaustion of the World's natural resources.
Overnight, or when your receiver is not
going to be used for long periods of time,
you can turn it off at the mains and this will
save energy (and save you money).
You will not have to re-install the receiver
when it is turned on again.
9
2
everyday operation
While using the GDB4 receiver to the full there are great many keys to use in different
situations. Many of the menu screens displayed by the receiver have reminders as to
which keys do what, at the base of the screen. In addition, many screens have further
help available which is displayed when the [i] key is pressed, as prompted at the bottom
right of the screen.
Providing your TV set SCART socket has switch control, pressing the [TV/DTV] key at
any time while watching television programmes will switch the TV set between displaying
the digital terrestrial television programme and its normal analogue television reception.
CHANGING CHANNELS
You can select the channel you wish to watch in one of four ways - stepping through
the channel list, selection by number, from the on-screen channel list, and using the
electronic programme guide (EPG).
To move through the channel list, press the [P+] or [P-] keys on the remote control.
Pressing the [P+] key will select the channel next in the channel list. Pressing the
[P-] key will select the previous channel in the list.
Pressing the [P+] key when the last channel in the list is being viewed will select the
first channel. Similarly, pressing the [P-] key when the first channel is displayed will
select the last channel in the channel list.
You can also select the required channel using its channel list number. Channel
numbers are entered using the number keys on the remote control handset and can
be up to three digits long.
Hint
The channel list numbers are assigned
by the broadcasters. Because not all
channels are broadcast free-to-air and
stored by the receiver, the channel list
numbers do not run continuously.
The fifteenth channel in the list, for
example, may not be channel number
15 but channel number 17.
When you press a number key on the
remote control, a small box appears in
the top left of the screen to show the
entered number. After each digit is
entered, the receiver will wait up to two
seconds for the next digit to be pressed
until either three digits have been entered
or you do not press a digit in time.
The channel corresponding to the
entered number in the box will then be
selected.
Hint
If you enter a number which does not
correspond to a stored channel, the next
valid channel number is selected instead.
If you enter a number greater than the
highest numbered channel in the channel
list, the receiver will select the last channel
in the list.

Information Banner
Whenever you change channel, using the [P+] and [P-] keys or the number keys, the
receiver displays the channel picture along with an information banner at the bottom of the
screen. This will remain on the screen for approximately three seconds. The information
banner can also be displayed at any time while watching TV by pressing the [i] key on the
remote control. Pressing the [i] key again removes the banner.

Current Programme
The channels are listed at the bottom of the screen, each with the 'current event' (the name
of the programme showing at that time) and the 'next event' (the following programme).
When the EPG screen is first displayed, the channel last watched is highlighted in the list
of channels. A quarter-screen image of this channel is displayed at the top right of the
screen along with the channel name and channel list number.
Hint
If the channel you have been viewing is a
digital teletext channel then no picture will
appear in the quarter-screen window.
Hint
Not all channels broadcast all the programme
information data. Some channels do not
provide the current and next event data and/or
the programme details. In this case the
programme names and/or the details are not
displayed. This is not a fault with your receiver.
Details of the current programme on that
channel (the name of the programme and,
typically, a synopsis with details of the stars
involved, the teams playing, or similar
information) along with the start and finish
times are displayed at the top left inside
the dark blue text window.
Moving the highlight through the list of
channels using the [UP] and [DOWN]
keys will change the programme details in
the text window to reflect the channel
highlighted. The quarter-screen window
continues to show the channel last watched,
so you can stay watching a programme
while at the same time browse the details
of what's on, on other channels.
You may then select the highlighted channel
for viewing on the quarter-screen window
by pressing the [SELECT] key.

your TV set, the sound level is not suddenly
very high.
You can silence the sound from the receiver by pressing the [MUTE] key. The sound
remains muted until the [MUTE] key is pressed again, the [V+] or [V-] keys are pressed,
or until the receiver is turned off and on again.
While the sound is muted in this way, the mute symbol is displayed in the top left of

everyday operation
DIGITAL TELETEXT
Many digital terrestrial television channels not only broadcast pictures and sound for
programmes but also pages of information on the programmes, the weather, news and
many other topics. This digital teletext can be displayed by the GDB4 receiver.
Some channels are entirely given over to digital teletext and carry no normal TV programme
at all. These dedicated digital teletext channels will not give a quarter-screen image in the
EPG or the Channel List screen. When such a channel is selected, after a brief pause, they
will usually display the opening page of information automatically.
Other channels have digital teletext pages broadcast alongside the television programme
and often include a reduced-size broadcast picture within digital teletext pages. These
usually require the [TEXT] button to be pressed to activate the digital teletext pages.
2
In both cases, moving through the different
pages of information is accomplished in a
variety of ways, dependent on the
individual broadcasters, but including use
of the [UP], [DOWN], [LEFT], [RIGHT] and
[SELECT] keys to select items from
on-screen menus, and the coloured keys
to jump directly to particular pages.
You can exit any digital teletext channel by
changing channel in any of the normal
ways. You can leave the digital teletext
function of a combined digital
teletext/programme channel, to return to
normal television viewing of that channel,
by pressing the [TEXT] key.
Hint
Calling for the information banner or any
menu on-screen stops the receiver from
displaying the digital teletext pages and
they are temporarily replaced by a blank
picture while the banner or menu is
displayed.. Digital teletext cannot be
accessed when the Subtitles are enabled
(See Section 2 - ADVANCED OPERATION Configuring Your Receiver.

WIDESCREEN
TV sets are available with screens of the standard (4:3) format and widescreen (16:9)
format. When you first installed your GDB4 receiver you specified the format of the
connected TV (this can now be altered if necessary; see Section 3 - ADVANCED
OPERATION - Configuring Your Receiver).
Digital terrestrial television broadcasts are also made in both standard and widescreen
formats. In particular, films and dramas tend to be broadcast in widescreen format to
closer emulate the cinema experience, but even some news bulletins are widescreen.
To help get the most from both TV set and programme when a widescreen film is
watched on a standard TV, or a standard broadcast is viewed on a widescreen set, the
GDB4 receiver includes the [WIDE] key.
So long as the receiver has been correctly set up for the TV set connected, a widescreen
programme will always be displayed correctly on a widescreen set, and a standard format
programme will correctly fill the screen of a standard format TV.
With a widescreen TV set displaying a standard format programme, the [WIDE] key
switches between displaying the picture with black bars down the sides, and enlarging
the picture so that it fills the whole width of the screen but the top and bottom are
cropped off.
With a standard format TV displaying a widescreen programme, the [WIDE] key switches
between displaying the picture with black bars at the top and bottom of the screen, and
filling the whole height of the screen but cropping the sides off according to instructions
broadcast with the programme (called 'pan and scan').
The effect of the [WIDE] key on the picture display is cancelled by pressing [WIDE] again,

pressing [MENU].
EDIT NAME
The channel names which appear in
the channel list and the information

characters that make up a channel name
can be highlighted using the [LEFT] or
[RIGHT] keys and the highlighted character
changed by pressing the [UP] or [DOWN]
keys to cycle through the alphabet, numbers
and other characters available.
DELETE
The initial installation of the GDB4
receiver can produce duplicate entries
in the channel list from transmitters
operating at different frequencies in
adjacent areas, and you may wish to
delete these duplicate entries from the
list. In addition, other channels which
you do not want in the list.
Highlight the channel to be deleted,
highlight the DELETE button at the base
of the screen using the [LEFT] or [RIGHT]

highlighted channel is deleted from the list.
You can now perform further editing on
the channel list, or return to normal
broadcast viewing by pressing the
[MENU] key.
Hint
You can also enter a channel name using
the number keys on the remote control.
Each key represents several letters and
pressing a key several times will enter
each letter (in both capitals and lower
case), and the number, in turn, in the
character position marked by the cursor.
The zero key enters all the punctuation
marks available and a blank space. With
practise, this is a very quick means of
entering the required letters into the
channel name.
When the required changes have been made, pressing [SELECT] stores the new name
and returns to the Channel List screen. Alternatively, pressing [MENU] will abandon the
name change and return to the previous name.
You can now perform further editing on the channel list, or return to normal broadcast
viewing by pressing the [MENU] key.

CHANNEL AND MENU PROTECTION
CHANNEL LOCK
Some channels broadcast material which you do not want younger members of the family
to watch. Any channel can be 'locked' so that it cannot be selected for viewing without first a
four-digit PIN code being entered. In this way any channel not suitable for younger viewers
can be protected.
The channel lock is applied with the Channel List menu. Press the [MENU] key on the remote
control handset to display the Main Menu and then, using the [UP] or [DOWN] keys on the
remote control, make sure that the first item, Channel List, is highlighted in yellow and press
the [SELECT] key.
Highlight the channel to be locked using the [UP] or [DOWN] keys. You can move through

icon is then displayed alongside the channel
name in the channel list.
You can now leave the Channel List screen and
return to normal TV viewing by pressing [MENU].
Any attempt to change channel to the locked
channel will now display the same window
requesting the PIN code and the channel will
only be displayed on entry of the correct code.
To remove the lock on a channel, repeat the

FAVOURITE CHANNELS
There will be some channels that you tend to watch more often and some only occasionally.
Although some duplicate channels you may want to delete from the channel list, others
although not watched frequently, you will not want to do away with altogether. The favourite
mode allows the most-watched channels to accessed more easily, leaving the less-watched
channels accessible but out of the way.
When the favourite mode is activated, the [P+] and [P-] keys cycle through the favourite
channels only and the EPG will list the favourite channels only (other channels can still be
accessed by channel list number or from the Channel List menu screen).
Any channel can be a favourite channel and the Channel List menu is used to label those

PROGRAMME REMINDERS AND TIMERS
With the greatly extended channel choice that digital terrestrial television brings, it
is all too easy to miss a favourite programme. The GDB4 receiver has two facilities
built in to help you make sure you catch all the TV shows you want.
PROGRAMME REMINDERS
Programme reminders can be set to signal that a programme is about to start when you
are watching another channel. A reminder is set from the Electronic Programme Guide
screen.
Press the [GUIDE] key to display the EPG screen and press [RIGHT] to display the next
programme details in the text window and highlight the name of the next programme in
the list of channels. Press [SELECT] when a programme you want to watch is highlighted
and the reminder icon is displayed against that programme's name.
You can exit the EPG screen in the normal way - pressing [GUIDE], [MENU]. Later,
shortly before the programme is due to start, the receiver will display a reminder on the
screen over the picture of the channel being viewed.
Use the [LEFT] or [RIGHT] keys to highlight the YES or NO buttons as appropriate and
press [SELECT]. If you select the YES button, the receiver switches over to the reminder
channel.
Note:Reminder events are ignored if any timer event is active at that time.
26
advanced operation
EVENT TIMER
You can also set a timer to switch the receiver to any channel without your intervention. This
is intended for making video recordings of programmes when you are out. If a single
programme is to be recorded, the receiver can be left switched to the required channel and
the timer set on the VCR. However, if two or more programmes on different channels are to
be recorded then the GDB4 receiver's own timer is set as well, to select the required channel
when it is needed.
Display the Main Menu by pressing the [MENU] key and highlight and select the Timers line
to display the Timer menu screen. Up to five separate timer events can be set and each is
displayed in the Timer screen, showing the event number, the channel to be selected, the
start time, end time, date and the mode - whether that event is active (and will be acted on)
or not.
To set an event, highlight its mode button using the [UP] or [DOWN] keys and press
[SELECT] to display the timer entry window. Here the five settings of channel name, start
time, end time, date and frequency mode can be set. You can move freely between each
setting using the [UP] and [DOWN] keys. The channel name is set using the [LEFT] or
[RIGHT] keys to display the channel which broadcasts the programme to be recorded.
The start time, end time and date are each set with the number keys on the remote control
in 24-hour format. The frequency mode determines how often the receiver operates this
event and is set with the [LEFT] or [RIGHT] keys to be either Once, Daily, or Weekly.

RE-INSTALLATION
Although your GDB4 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.

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 [SELECT] is pressed, the
receiver searches that frequency and display
a list of the channels found. Before returning
to the Installation menu.
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.
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.

appendix a - safety
POWER
The receiver should be plugged into a 230V to 240V AC, 50Hz supply only.
LEADS
Ensure the power supply lead, and all other leads, are positioned so they are not likely to be
walked on or pinched by things placed on or against them. Pay particular attention to the
power lead, where it enters the mains plug and where it comes out of the receiver. Do not
connect or adjust leads when the receiver is plugged in.
TEMPERATURE AND MOISTURE
Do not leave or use the receiver in a hot, cold or humid area. Do not allow the receiver to get
wet - from drips or splashes - as this may be dangerous. Do not place water-filled objects
such as flower vases, on top of the receiver.
VENTILATION
Slots and openings in the receiver's cover are for ventilation. Do not cover or block them as
this could lead to overheating.
CLEANING
Unplug the receiver before it is cleaned. Use a lightly dampened cloth only. Do not use liquid
or aerosol cleaners.
HEAT AND FLAMES
The receiver should not be placed near to naked flames or sources of intense heat, such as
an electric fire. Ensure that no naked flames sources, such as lighted candles, are placed on
top of the Receiver.
LIGHTNING
Unplug your receiver from the wall socket if there is a storm or lightning, or if it is to be unused
for a long time.
REPLACEMENT PARTS
If your receiver needs a replacement part, ensure the person undertaking the repair uses parts
which are specified by the manufacturer or have the same specifications as the original part.
Other parts may cause a fire, electric shock or other hazards.
BATTERY DISPOSAL
Please ensure that exhausted batteries from the remote control handset are disposed of safely.
SERVICING
Ensure the person who services your receiver is qualified to do so. Do not remove the cover
yourself - you could get an electric shock.
We are proud to offer a high-quality product. To keep this level of quality, your receiver should
be serviced at a Goodmans authorised service centre.
