Putting the receiver into operation 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 (see page 51). Ensu
