Troubleshooting - Albrecht Audio DR 57 Manuel

10. Troubleshooting

Problem: DAB transmission via FM to the car radio is poor,
with interference or not working at all.
Please use the supplied USB cable and cigarette adapter. Other
cables often do not suppress interferences sufficiently.
Problem: No DAB reception when the DR 57 is connected
via the line-in input to the car radio, although the DAB signal
strength is good.
Please switch the DR 57 to the "AUX" mode in the menu.
Poor DAB reception on some motorways or roads, part 1.
Because the DAB network is not yet fully expanded, this can
result in poor reception while driving in some rual areas that are
not yet fully developed. Therefore, please test the DR 57 receiv-
er in a better developed area before you send in the device for
repair because of faulty reception.
Problem: Poor DAB reception, part 2.
Commercially available USB adapters without interference sup-
pression are certainly suitable for many applications, but not ad-
equate for powerful DAB receivers. Therefore, for optimum re-
ception, use the USB adapter and the cigarette adapter supplied
by us which are specifically designed for the DR 57 receiver.
Problem: Poor DAB reception, part 3.
Check whether the supplied DAB antenna was installed exactly
as described in the installation instructions and if it is also prop-
erly connected to the vehicle ground. Other electronic devices
that are not interference suppressed (such as low-cost dash
cams), especially in the interior of the vehicle, may interfere with
the DAB reception.
