INSTALLATION
ADDITIONAL REAR PANEL FUNCTIONS
Data service switch: DAB makes provision for providing dedicated
text and other data services in the multiplex datastream.This switch
can be used to prevent data services from appearing among the
available services on the tuner's display. The tuner cannot process
data services by itself so it makes sense to leave this switch in to
disable them.
RDI out: This is an optical data output that may allow future
expansion to use certain data services via an outboard device such
as a personal computer. RDI = Radio Data Interface. The Data
Service switch will need to be out to access the data streams from
these services.
There is a small aerial made by Bosch which is suitable for L-Band
and Band III and has been used with good results. The Bosch part
number is: FOIDEOO144

SETTING UP THE AERIAL
Your new Arcam tuner is capable of superb reception but only if it
is receiving a good quality transmission signal.
As the signal is so important for good reception we have created a
quick reference guide to setting up the aerial.
We recommend that a roof mounted aerial is used where possible,
to ensure the best possible performance. The best aerial to use is a
Band 3 (multi-element Yagi) array, if you are a long way from a
transmitter, or an omnidirectional or folded dipole if you are close to
more than one transmitter In the U.K. this should be mounted with
all elements vertical as the transmissions are vertically polarised. Be
sure to use a good quality coaxial cable such as URM43, CT-100 or
similar For band 3 use you can use either 50 ohm or 75 ohm cable
provided it is good quality. Always use 50 ohm cable for L band use.
However a standard Band 2 FM or UHF TV aerial may work
provided it is pointed in the right direction. We would recommend
that this is tried if one is already installed.Your dealer can advise on
which direction to point the aerial.
If the signal is strong the supplied indoor aerial may be sufficient. It
should be hung on a wall with both wires fully stretched out,
However there will be many areas where one DAB ensemble
(group of stations transmitted together) is strong and others are
weak. An external aerial is desirable in these cases in order to receive
a higher number of services. If the DAB services in your area are
transmitted on L band (1.5 GHz) then consult your dealer with
regard to the best aerial to use.
