Bluetooth mode
The Bluetooth mode on your clock radio allows you to play audio, play sound from video les and stream music from Bluetooth capable devices such
as your mobile phone, computer, tablet etc. through your clock radio's loudspeakers.
● When a Bluetooth enabled device such as your Sound 48 clock radio is in a 'discoverable' state other Bluetooth devices can detect, pair with or
connect to it.
● 'Bluetooth pairing' occurs when two Bluetooth enabled devices agree to establish a connection and communicate with each other.
Connecting Bluetooth devices
1 Ensure that the Bluetooth capability on your phone, tablet or PC is enabled. You may
need to refer to the user documentation for your device, since the method will vary
with each device.
2 Ensure your clock radio is switched on.
3 Press the Mode button on your clock radio until the Bluetooth mode is selected. Your
clock radio will become 'discoverable' and 'Connecting' will show on the display.
4 Using the Bluetooth settings on your phone, tablet or PC direct it to search for
'discoverable' devices. After a few seconds, you should see a device named 'Sound
48'. Just occasionally it may take longer for the clock radio to be found by your device.
5 Select 'Sound 48' to cause your phone, tablet or PC to pair with your clock radio and
to establish a connection.
The connection will be established and you can now begin playing music from your
smart-phone, tablet, etc.
Some Bluetooth devices may require a 'Passkey' (an authentication key) in order to
establish a link between devices. A passkey is similar to a password, although you only
need to use the passkey once to establish a link. If your device asks for a passkey to be
able to pair with your clock radio then enter a code of 0000 (four zeroes).

at any one time. Once you have a Bluetooth enabled device connected
to your clock radio it cannot be interrupted by another Bluetooth device
unless you choose to break the connection.

may fail to playback some CD-R/CD-RW discs due to poor recording

WARNING
CLASS 1 LASER PRODUCT means that the laser's construction makes
it inherently safe so that the legally prescribed maximum permissible
radiation values can never be exceeded.
Caution:Using anyequipmentordevicesotherthanthose describedand
specied in these operating instructions, or tampering with the unit in any
way, can result in dangerous exposure to radiation.
MP3 / WMA / AAC CD Mode
The Sound 48 is able to play CD-R and CD-RW discs containing MP3 /
WMA / AAC les with a maximum of 255 les per folder. An MP3 / WMA
/ AAC CD should not contain more than a combined total of 999 les
and folders. MP3, WMA and AAC les should be created with an audio
sample rate of 44.1kHz (this is normal for les originally created from
audio CDs). Folders may be nested but to a maximum of 8 levels. Folder
and le names should ideally be less than 30 characters in length. Tags
for title / artist / album information in the les should ideally be less than
30 characters in length. Within a folder, les or folders written earlier
will generally be played before those written later and les have higher
priority than nested folders.
Therearemany possible variations intheformatting of CD-RandCD-RW
discs with audio les, but regular CD burning software should generally
give good results with default settings. Should problems arise, contact
the customer services of your CD burner or software manufacturer. When
creating audio CDs, please observe all legal guidelines and ensure that
the copyright of third parties is not infringed.
