Q: What is the best position for the receiver
in the room?
A: If possible, change the position of the transmit-
ters and receivers so that there is always a direct line
of sight between the associated transmitters and
receivers.
A: Switch off all other radio links operating in the
2.4 GHz frequency band or try to keep the distance
between potential sources of interference and the
ew D1 system components as large as possible.
Sources of interference are devices, such a WiFi
routers or Bluetooth-enabled devices, that operate
in the same frequency band as the ew D1 system
components. We recommend a minimum distance
of 10 meters between a WiFi router and the ew D1
system components.
A: Certain building layouts (e.g. very large, empty
halls) and materials (metal building materials in
walls and ceilings) can also reduce the transmission
range.
Q: Can I use the ew D1 system simultane-
ously with active WiFi connections?
A: In general, this is possible. You can, for example,
control the ew D1 system using the "Wireless System
Remote" app. We recommend, however, to use a
dual-band WiFi router and deactivate its 2.4 GHz
band. If you have to operate the WiFi router in the
2.4 GHz band, ensure the maximum distance possible
between the WiFi router and your receivers in order
to avoid interference.

Q: Does an ew D1 system interfere with a
WiFi connection so that dropouts and errors
can occur during data exchange via WiFi?
A: The ew D1 system avoids frequencies that are
already allocated to other systems and automatically
uses unused frequencies so that, in general, interfer-
ence should be reduced to a minimum. If, however,
the frequency band is heavily occupied, interference
can occur in rare cases.
Q: What can I do if my Bluetooth devices do
not work when ew D1 radio links are oper-
ated in proximity?
System
A: If your Bluetooth devices are subject to interfer-
ence, we recommend that you pair the Bluetooth
devices again after putting an ew D1 system into
operation. As a basic principle, you should keep the
distance between Bluetooth devices and the ew D1
system components as large as possible.
Q: Why does the operating time of the
transmitter vary (only applies to the -NH
country variant for the Americas)?
A: Depending on the number of source of interfer-
ence in the proximity and the length of the radio link,
the handheld or bodypack transmitter transmits us-
ing adaptive transmission power (-NH country vari-
ant only. This greatly influences the battery power
consumption.
A: Please note that the displayed remaining battery
life is the minimum battery life.
Q: Which batteries can I use?
A:
You require two AA size batteries (1.5 V) per
transmitter.
A:
You can use all standard alkaline or lithium pri-
mary cells.
Q: Can I also power the transmitters using
accupacks?
A: You can power the transmitters either with bat-
teries or with one of the following accupacks which
are available as accessories:
BA 10 (Cat. No.: 505972) for the
handheld transmitter
BA 30 (Cat. No.: 505974) for the
bodypack transmitter
A: You can charge the accupack via a standard USB
power supply/charger or via the USB port of a com-
puter.
A: We recommend only using original Sennheiser ac-
cupacks. Sennheiser accupacks provide a longer bat-
tery life and the remaining battery life is displayed in
hours.
A: Do not use NiMH rechargeable batteries. They
only have a voltage of 1.25 V instead of the required
1.5 V. This causes that the remaining battery life is
not displayed correctly.
