Using the Cosmetic Trim Ring
A cosmetic trim ring is packaged with the
head unit for installation fexibility. This unit
will ft into most import dashes with little or
no modifcation to the dash board/cavity.
Some US domestic vehicle dashes will
accept a Double-DIN chassis, but there is
usually a small gap between the radio and
dash piece after installation is complete. In
this case, use the appropriate trim ring to
conceal any gaps that may be present.
MOUNTING THE DAB+ AERIAL
The aerial must be mount in such a manner that it does not impair vision when driving.
The aerial should preferably be mounted on the windscreen from the inside.
Due to the polarisation of the DAB transmission signal, the aerial must be mounted vertical to the ground.
The distance to other aerials must be more than 80 mm. On vehicles with windscreen heater, take care that the
aerial is not mounted on top of the heating wires.
Before applying the aerial, the windscreen must be clean, dry and free of grease. If necessary, clean the wind-
screen and remove all cleaning agent in order to ensure for a safe adhesion of the aerial adhesive tape.
In event of low temperatures, the windscreen should be warmed-up using the vehicle heater to allow the aerial ad-
hesive tape to bond safely. The aerial is only intended for being installed once (sticking on). Please do not remove
the aerial and remount it. The adhesive tape will be damaged when removed.
Determine the installation location of the aerial according to the instructions above.
Remove the white protective film on the back side of the black aerial housing that conceals the adhesive tape for
the aerial housing.
