Blaupunkt 400-Serie Bedienungsanleitung Seite 37

Check for correct connection of the device; under no
circumstances should you connect the car positive pole
directly to the radio without first checking the PIN assignment.
Have the installation performed/checked by a professional.
• Settings and/or preset stations are lost, the time is not
displayed properly:
As a rule, the device saves the settings permanently, even
without power supply. However, some settings are
permanently saved only after properly turned off, so it is
important that the device is properly turned off.
Functions such as time, last source, last USB/CD playback
position require constant power supply. For proper operation,
the unit must be properly connected to a continuous power
supply that cannot be interrupted.
• The unit does not receive radio signal or the signal is weak:
Check the antenna for your reception area.
Check to see if a phantom power supply adapter may be
needed.
Is the antenna installed correctly? Many antennas require a
counterpole (car body).
LED lights or other electrical components may interfere with
radio reception, so such interference should be excluded.
When using the radio for the first time, make sure the unit is
set to the correct radio region (see "SETTINGS").
• NO SIGNAL or NO SERVICE is suddenly displayed in the DAB
mode:
The current ENSEMBLE (programme package) signal is too
weak and audio signal decoding is not possible. Select another
ENSAMBLE or check the DAB antenna.
• The unit suddenly displays SEEK PI/SEEK TA or changes
stations during radio operation:
Check the antenna and device settings. If necessary, deactivate
the alternative frequency function (see "SETTINGS"). Poor
reception may cause the unit to change stations if the Traffic
Announcement function is enabled.
• In radio mode, the unit does not display the station name
correctly:
Adjust the display as required with the DIS button. Check
reception (check the antenna).
Note: Some stations broadcast additional information instead
of the RDS station name; this is not affected by the unit.
• USB, CD, SD or other storage media do not work:
Check other storage media for correct functioning, format
storage media, and play different files.
• Bluetooth® problems (phonebook is not displayed, the
phone does not connect, the caller cannot be heard):
Check for software updates for your phone and/or radio.
Remove the radio from the list on the phone, then reconnect.
Confirm all authorisation requests on the phone giving the YES
reply.
Try using a different phone.
• The caller does not hear me:
Check the external microphone for correct connection. Check
the microphone setting in the Bluetooth® settings (if
available).
Try using a different phone.
• The SUB-OUT option or its settings on the unit do not work:
Make sure the subwoofer is properly connected to the SUB-
Out output of the unit, otherwise the options in the sound
settings do not have any effect.
• The issue/malfunction is not specified in this case. The
device or its function does not work/behave as expected:
Reset the device to factory defaults in MENU -> VARIOUS ->
NORMSET.
Verify that the software is up to date. Current software updates
are available on our website or can be ordered through our
service.
Note: A detailed description of the malfunction and the
current device software version is required to contact the
service.
