Preparing the receiver for use
Mounting the receiver feet
To ensure that the receiver cannot slip on the surface on which it is placed,
four self-adhesive soft rubber feet are supplied.
̈ Ensure that the base of the receiver is clean and free from grease before
mounting the rubber feet.
̈ Fix the rubber feet to the base of the receiver by peeling of the safety
paper and fitting them as shown in the digram on the left.
Attention!
Some furniture surfaces have been treated with varnish, polish or
synthetics which might cause stains when they come into contact with
other synthetics. Despite a thorough testing of the synthetics used by us,
we cannot rule out the possibility of staining.
Connecting the antennas
The supplied telescopic antennas can be mounted quickly and easily and are
suitable for all applications where – good reception conditions provided – a
wireless transmission system is to be used without a large amount of
installation work.
̈ Connect the telescopic antennas ƽ to the BNC sockets µ and Ƹ at the
rear of the receiver.
̈ Pull the telescopic antennas out and align them upwards in a V-shape.
Connecting and mounting remote antennas
When the receiver position is not the best antenna position for optimum
reception, you can use remote antennas. These are available as accessories.
̈ Connect the remote antennas to the BNC sockets µ and Ƹ at the rear of
the receiver. For connecting the antennas, use RG 58 co-axial cable. Ready
made up antenna cables from Sennheiser are available as accessories with
lengths of 1 m, 5 m and 10 m (see “Accessories” on page 69).
Attention!
To supply an active directional antenna (e.g. A 12 AD-UHF for the UHF
range) or an antenna booster (e.g. AB 1), a direct voltage (which cannot
be switched off) is output via the BNC sockets. If you use antennas from
other manufacturers, take into account that these must be installed with
direct voltage decoupling, i.e. isolated. The output voltage supply is short-
circuit proof. An active antenna connected to this supply increases the
current consumption of the overall unit.
