Volume adjustment
To achieve the best possible playback quality, you should only adjust the
volume on the
itself: set the playback volume as high as possible on your
mobile device, but not so high that the signal is distorted.
Any further changes to volume should then be made using the
/
button on the
or the FM 100.
NOTES
The
has been tested with a large number of Bluetooth-capable mobile
devices. However, we are unable to guarantee general compatibility with all
devices available commercially since the range of equipment is so wide, and
the various implementations of the Bluetooth standard differ widely in some
cases. If you encounter a problem with Bluetooth transfer, please contact the
manufacturer of the mobile device.
The maximum range of a Bluetooth audio transfer is normally about 3 to 5
metres, but the effective range may be affected by a number of factors. To
achieve good range and interference-free reception there should be no
obstacles or persons between the
and the mobile device.
Bluetooth audio transfers take place in what is known as the “everyman
frequency band”, in which many different radio transmitters operate - including
WLAN, garage door openers, baby intercoms, weather stations, etc. Radio
interference caused by these other services may cause brief dropouts or - in
rare cases - even failure of the connection, and such problems cannot be
excluded. If problems of this kind occur frequently in your environment, we
recommend that you use the Streaming Client or the USB input of the
instead of Bluetooth.
By their nature, Bluetooth transmissions always involve data reduction, and the
attainable sound quality varies according to the mobile device in use, and the
format of the music to be played. As a basic rule the maximum quality of music
which is already stored in a data-reduced format, such as MP3, AAC, WMA or
OGG-Vorbis, is worse than with uncompressed formats such as WAV or FLAC.
For the highest reproduction quality we always recommend the use of the
Streaming Client or the USB input of the
instead of Bluetooth.
