CAUTION!
Rack mounting poses risks
When installing the device in a closed 19" rack or multi-rack
assembly, please consider that, during operation, the ambient
temperature, the mechanical load 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 stated
in the specifications. See "SPECIFICATIONS".
▷Ensure sufficient ventilation; if necessary, provide addi-
tional ventilation.
▷Make sure that the mechanical load of the rack is even.
▷When connecting to the power supply system, observe the
information indicated on the type plate. Avoid overloading
the circuits. If necessary, provide overcurrent protection.
▷When mounting in a rack, please note that intrinsically
harmless leakage currents of the individual power supply
units may accumulate, thereby exceeding the permissible
limit value. As a remedy, ground the rack via an additional
ground connection.

System -> Link Density menu item
Link Density mode (LD mode)
LD mode doubles the number of usable carrier frequencies in
the available spectrum, as the minimum distance for the equi-
distant frequency grid is halved.
This is achieved by reducing the modulation bandwidth of the
transmitter. This means that a much smaller frequency spac-
ing between neighboring frequencies can be selected, and
therefore more frequencies can be used in the same available
spectrum without intermodulation.
LD mode is recommended if the following criteria are met:
•The required number of channels cannot be achieved using
the normal mode, as there may be only a small spectrum
available.
•The distance between the transmitters and the antennas is
not too great.
To open the Link Density menu item:
▷In the System menu, navigate to the Link Density menu
item.
▷Press the jog dial to open the menu.

Connecting to the EW-D EM receiver /
synchronizing the EW-D EM
To establish a radio link between the transmitter and receiver,
we recommend the following procedure.
In order to establish a connection between a receiver and
transmitters of the EW-D series, the devices must always be
synchronized with each other.
To successfully connect a receiver and a transmitter, both de-
vices must have the same frequency range.
Step 1: Set a free frequency
We recommend using the AUTO SCAN function, as this is the
most reliable way to identify free frequencies (see "AUTO
SCAN menu item").
If you know free frequencies in your area, you can also set the
frequency manually (see "CHANNEL menu item" or "TUNE
menu item").
Step 2: Pairing a receiver with a transmitter

Installing the EW-D ASA in a rack
ATTENTION
Rack mounting poses risks
When installing the device in a closed 19" rack or multi-rack
assembly, please consider that, during operation, the ambient
temperature, the mechanical load 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 stated
in the specifications. See "SPECIFICATIONS".
▷Ensure sufficient ventilation; if necessary, provide addi-
tional ventilation.
▷Make sure that the mechanical load of the rack is even.
▷When connecting to the power supply system, observe the
information indicated on the type plate. Avoid overloading
the circuits. If necessary, provide overcurrent protection.
▷When mounting in a rack, please note that intrinsically
harmless leakage currents of the individual power supply
units may accumulate, thereby exceeding the permissible
limit value. As a remedy, ground the rack via an additional
ground connection.
To mount the antenna splitter in a rack, you will need the GA 3
rack mount kit (optional accessory).
Rack mounting is carried out in the same way as for the EW-
D EM receiver: "Installing receivers in a rack".
