5. Frequently asked questions (FAQs)
Why does my audio not work although the source
AUX BT is activated?
When the source AUX BT is activated, audio may not
function even though the required Bluetooth
is operative. This may be due to several causes:
1. Some devices do not permit remote starting of the
audio player. In this case the player must be started
manually via the mobile phone; after this, the audio
player can be operated using the PCM.
2. There is no memory card in the mobile phone, or the
music is not in the expected directory of the memory
card and cannot be located by the telephone.
3. With some mobile phones or Bluetooth
volume of the music played via the PCM depends on
the volume setting on the mobile device. In this case
the volume on the mobile phone or Bluetooth
may need to be increased.
4. In simple implementations, the same command is
used to operate the functions 'Play' and 'Pause',
without giving a status report on the current status of
the player. This may result in the player being paused
instead of playing. With some phones, the problem
also occurs after a phone call but can generally be
solved by pressing the volume control twice or pressing
the arrow buttons. Otherwise the audio player must
be started on the mobile phone itself.
Why is audio transmission via AUX BT sometimes
impaired on occasion?
In some situations, the quality of audio transmission via
connection AUX BT may be impaired by the limited bandwidth at
