HOW TO CHANGED THE CERAMIC FILTERS
This model is used two ceramic filters of CF2 and CF3.
You must used same type of color marked ceramic filters in order
to meet same specifications.
Therefore, the ceramic filter must changed two pieces together
since it’s supply two pieces in one package as a spare parts.

What is RDS?
The Radio Data System, RDS is a
radio digital information system
developed by the European
Broadcasting Union, EBU and
introduced in 1987. Using the 57 kHz
sub-carrier of FM broadcasting, the
RDS enables you to receive a variety
of information such as station names
and traffic information.
However, the availability of the RDS
data varies according to areas.
Therefore, there may be cases where
you may not be able to receive some
of the following data.
