Avoiding sources of interference Featuring automatic interference management, the devices are capable of
avoiding interfering signals at any time by automatically moving together to
unused frequencies in the 2.4 GHz frequency band, without any audio inter-
ruption. However, the number of usable radio links is reduced if there are
active sources of interference in the vicinity of the devices.
왘Switch off possible sources of interference operating in the 2.4 GHz fre-
quency band.
Possible sources of interference use e.g. WiFi or Bluetooth.
Infrared remote controls and headphones, DECT headphones and UHF radio
links (e.g. Sennheiser evolution wireless G3) do not represent a source of
interference and can remain switched on.
왘If you want to use WiFi while operating devices of the
series, use a dual-band WiFi router and deactivate its 2.4 GHz frequency
band in order to minimize interference to the radio links.
If conditions are optimal, you can operate up to 15 radio links simultaneously
(for details, see “Using the devices in multi-channel operation” on page 29).
Direct line of sight recommended Walls and other obstacles will reduce the range. Therefore, there should
always be a direct line of sight between the transmitting antenna and the
receiving antennas of a radio link. To ensure this, you can mount the antennas
of the receiver in different ways.
• When using the EM D1 as a stand-alone receiver, you can mount the sup-
plied 2G4 rod antennas to the rear of the receiver (see page 16).
• When rack-mounting the receiver, you should use the GA 4 rack-mount kit
to mount the receiver antennas to the front of the rack (see page 19).
You can identify and locate sources of interference using a WiFi scan-
ning tool.

Fitting the device feet
왘Clean the recesses for the device feet at base of the receiver.
왘Fit the device feet to the recesses of the receiver.
왘Place the receiver on a flat, horizontal surface.
The device feet will adhere reliably to the receiver only after some time.
Avoid moving the receiver during this time.
Mounting the rack mount “ears”
To fasten the rack mount “ears”:
왘Unscrew and remove the two recessed head screws on each side of the
receiver.
왘Secure the rack mount “ears” 1to the sides of the receiver using the pre-
viously removed recessed head screws.
Connecting the rod antennas to the receiver
The supplied 2G4 rod antennas can be mounted quickly and easily. The rod
antennas are suitable for all applications where – good reception conditions
provided – a wireless transmission system is to be used without a large
amount of installation work
ATTENTION
Risk of staining of furniture surfaces!
Some furniture surfaces have been treated with varnish, polish or synthetics
which might cause stains when they come into contact with other synthetics.
Despite a thorough testing of the synthetics used by us, we cannot rule out
the possibility of staining.
왘Do not place the receiver on delicate surfaces.
Do not fit the device feet when mounting the receiver into a rack.
The rack mount “ears” are designed to help protect the operating ele-
ments from damage or deformation, e.g. if the receiver is dropped.
왘Therefore, always fasten the rack mount “ears”, even if you do not

Mounting the receiver into a 19" rack
For mounting one or several receiver into a rack, you require the optional GA 4
rack-mount kit. The GA 4 rack-mount kit is supplied with individually pur-
chased receivers and is also available separately as an accessory.
Using the GA 4 rack-mount kit, you can:
• mount a single receiver into a 19" rack (see page 18),
• mount the two 2G4 rod antennas to the front of the rack (see page 19) or
• mount two receivers side by side into a 19" rack (see page 19).
The GA 4 rack-mount kit consists of:
When rack-mounting the receiver, you should use the GA 4 rack-mount
kit to mount the receiver antennas to the front of the rack (see next
chapter).
ATTENTION
Danger due to high temperature, mechanical loading or electric leakage cur-
rents
When rack-mounted, the receivers can be damaged by overheat or excessive
mechanical loading.
왘Make sure that the temperature within the rack does not exceed the per-
missible temperature limit specified in the specifications (see page 46).
왘Make sure that the receivers in the rack are not mechanically loaded.
왘Make sure that circuits are not overloaded by providing overcurrent protec-
tion, if necessary.
왘Make sure that the sum of the leakage currents of all power supply units do
not exceed the allowable limit values by grounding the rack via an addi-
tional ground connection, if necessary.
Do not fit the device feet when mounting the receiver into a 19" rack.
