Cause:
Poor contact of a Cinch plug or a
faulty Cinch lead.
Remedy:

Problem: The unit switches off repea-
tedly at fairly high volume le-

Cause1:
Overheating due to heat build-
up.
Remedy:
Set up the unit in a position whe-
re there is an unobstructed flow
of cooling air.
Cause2: Overheating due to insufficient

Problem: The RDS station name does
not appear on the screen.
Cause1:
The station is not broadcasting
RDS information, or is not cor-
rectly tuned in.
Remedy:
Tune in the station so that the
tuning indicator is in the centre
position.
Cause2:
The tuner is picking up interfer-
ence on the same frequency, or
the signal strength is too low.
Remedy:
Select only those stations which
can be received with good sig-
nal strength, devoid of back-
ground hiss and interference.
Problem: When you switch presets the
RDS station name does not
appear correctly, or only after
a long wait.
Cause:
The name was not picked up
correctly during the preset stor-
ing procedure, or the station is
broadcasting the station name as
a running script, contrary to the
RDS norms.
Remedy:
Call up the preset and wait until
the station name appears cor-
rectly on the screen, then store it
manually.
