Using your clock radio for the first time
1. Place your clock radio on a flat surface.
2. Fully extend the wire aerial located on the rear of your clock radio.
Place the wire antenna so that it is as straight as possible extending
either above or below the clock radio.
3. Insert the adaptor plug into the DC Input socket located on the rear
of your clock radio.
4. Plug the adaptor into a standard 13amp mains socket outlet.
IMPORTANT: The mains adaptor is used as the means of connecting
the clock radio to the mains supply. The mains socket used for the clock
radio must remain accessible during normal use. In order to disconnect
the clock radio from the mains completely, the mains adaptor should
be removed from the mains socket outlet completely.
5. When your clock radio is first switched on the display will show 'Setting
Clock' and a station search will be performed automatically.
6. When a signal has been found, the clock information will appear on
the display. Press the Display button to toggle between showing the
time only or showing both the date and time.
7. If no signals are found 'Clock not set' will be displayed. It may then
be necessary to relocate your clock radio to a position giving better
reception. You should then carry out an auto scan to find stations as
described on page 9.

Presetting stations
You may store your preferred DAB and FM radio stations to the preset
station memories. There are 20 memory presets in your clock radio, 10
for DAB and 10 for FM. Presets are remembered by your clock radio in
the event of a power failure.
The procedure for setting presets and using them to tune to stations is the
same for FM and DAB modes, and is described below.
1. Press the On / Off button to switch on your clock radio.
Stereo / Mono setting - FM
Your radio will play stereo FM broadcasts in stereo provided that the
received signal is of adequate strength. However, as a stereo signal
becomes weaker the audio signal will become poorer. It may be preferable
to force the radio to play the station in mono in order to reduce the level
of background hiss.
1. Press the On / Off button to switch on your clock radio.
2. Tune to the required FM radio station as previously described (see
pages 12, 13).
3. Press and release the Select button so that the display shows 'Radio
mode: Mono'. The radio will play the current station in mono.
The mono override is a temporary setting and is applied to the currently
tuned station only. It is cancelled automatically by tuning to another
station.
4. If you wish to cancel the Mono override while listening to the currently
tuned radio station, press and release the Select button so that the
display shows 'Radio mode:Auto'The radio will play the current station
in stereo if the signal is sufficiently strong.

Compact discs
Use only Digital Audio CDs which have the symbol.
Never write on a CD or attach any sticker to the CD. Always hold the CD
at the edge and store it in its box after use with the label facing up.
To remove dust and dirt, breathe on the CD and wipe it with a soft, lint free
cloth in a straight line from the centre towards the edge.
Cleaning agents may damage the CD.
Do not expose the CD to rain, moisture, sand or to excessive heat. (e.g
from heating equipment or in motor cars parked in the sun).
CD-R/CD-RW discs
Your Sound 38 can playback CDDA format audio CD-R/CD-RW discs that
have been finalised* upon completion of recording.
Your Sound 38 may fail to playback some CD-R/CD-RW discs due to poor
recording and wide variation in quality of the CD-R/CD-RW disc.
*Finalising enables a CD-R/CD-RW disc to playback on audio players
such as your Sound 38.

MP3 / WMA CD Mode
The Sound 38 is able to play CD-R and CD-RW discs containing MP3
or WMA files.
In MP3 / WMAmode the terms "album" and "file" are very important. "Album"
corresponds to a folder on a PC, "File " to an audio track in MP3 or WMA
format. The clock radio reads MP3 or WMA files with a maximum of 255
files per folder. An MP3 or WMA CD may not contain more than 512 files or
albums in total. MP3 or WMA files must be created with an audio sample
rate of 44.1kHz (this is normal for files created from CD audio content).
Both MP3 and WMA files may be recorded on to the same media.
When burning CD-R and CD-RWs with audio files, various problems may
arise which could lead to interference in playback. This can be caused
by faulty software or hardware settings in your PC or by the CD being
used. Should such problems arise, contact the customer services of your
CD burner or software manufacturer or look for relevant information, for
example on the internet. When you are making audio CDs, observe all legal
guidelines and ensure that the copyright of third parties is not infringed.
