Putting the receiver into operation
Setting up the receiver on a flat surface
왘
Clean the base of the receiver where you want to fix the device feet.
왘
Fit the device feet to the four corners of the receiver.
왘
Place the receiver on a flat, horizontal surface. Please note that the device feet can leave
stains on delicate surfaces.
왘
Connect the antennas (see page 9).
Mounting the receiver into a 19” rack
왘
Slide the receiver into the 19” rack.
왘
Secure the rack mount “ears”
쐃
to the rack using four screws (not included in the
delivery).
왘
Connect the antennas (see next chapter).
Connecting the antennas
Do not fit the device feet when mounting the receiver into a 19” rack.
CAUTION! Risks when rack mounting the receiver!
When installing the device in a closed or multi-rack assembly, please consider that, during
operation, the ambient temperature, the mechanical loading and the electrical potentials will
be different from those of devices which are not mounted into a rack.
왘
Make sure that the ambient temperature within the rack does not exceed the permissible
temperature limit specified in the specifications.
왘
Ensure sufficient ventilation; if necessary, provide additional ventilation.
왘
Make sure that the mechanical loading of the rack is even.
왘
When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
왘
When rack mounting, please note that intrinsically harmless leakage currents of the indi-
vidual mains units may accumulate, thereby exceeding the allowable limit value. As a
remedy, ground the rack via an additional ground connection.

CAUTION! Danger of damage to the antennas
To supply an active directional antenna (e.g. A 3700 for the UHF range) or an antenna
booster (e.g. AB 3700), a direct voltage (which cannot be switched off) is output via the
antenna sockets of the receiver. If you use antennas from other manufacturers, take into
account that these must be installed with direct voltage decoupling. The output voltage
supply is short circuit-proof, but an active antenna connected to this supply increases the
current consumption of the overall device.
