Putting the receiver into operation

Putting the receiver into operation

Setting up the receiver on a flat surface

Do not fit the device feet when mounting the receiver into a 19” rack.

￿Clean the base of the receiver where you want to fix the device feet.

￿Fit the device feet to the four corners of the receiver.

￿Place the receiver on a flat, horizontal surface. Please note that the device feet can leave stains on delicate surfaces.

￿Connect the antennas (see page 9).

	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.

￿Make sure that the ambient temperature within the rack does not exceed the permissible temperature limit specified in the specifications.

￿Ensure sufficient ventilation; if necessary, provide additional ventilation.

￿Make sure that the mechanical loading of the rack is even.

￿When connecting to the power supply, observe the information indicated on the type plate. Avoid circuit overloading. If necessary, provide overcurrent protection.

￿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.

￿￿ Slide the receiver into the 19” rack.

￿Secure the rack mount “ears” ￿ to the rack using four screws (not included in the

	PE	delivery).

	Connecting the antennas
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.
