̈ Position antennas in the same room in which the transmission takes
place! Maintain a minimum distance of 1 m between antennas and a
minimum distance of 50 cm between antennas and metal objects
(including reinforced concrete walls).
Daisy chaining receivers
The receivers feature an integrated antenna splitter so that up to eight
receivers can be daisy chained using the supplied short antenna daisy
chain cables. The type plate U indicates the daisy chained frequency
range.
̈ Connect the two supplied antennas or two remote antennas (available
as accessories) to the BNC sockets O and R at the rear of the first
receiver.
̈ Use the supplied 50-Ω antenna daisy chain cables to daisy chain the
receivers as shown in the diagram on the left.
Connecting the receiver to the mains/
disconnecting the receiver from the mains
The receiver has no mains switch. To connect the receiver to the mains:
̈ Connect the supplied mains cable to the 3-pin mains socket D.
̈ Plug the mains connector into the wall socket.
To disconnect the receiver from the mains:
̈ Pull out the mains connector from the wall socket.
All daisy chained signals are interrupted, i.e.:

the booster supply voltage,
the signal of the external word clock generator.
If the booster supply voltage is switched on (see page 31), it
remains switched on even when the receiver is switched off.

The antenna signals are also daisy chained when a receiver is
switched off. If the booster supply voltage is switched on (see
page 31), it remains switched on even when the receiver is
switched off.

If you connect the receiver to an unsuitable power supply,
this can cause damage to the device.

the mains (100 to 240 V AC, 50 or 60 Hz).
̈ Ensure a reliable mains ground connection of the receiver
– especially when you are using multi-outlet power strips
or extension cables.
