2 Important safety instructions
The ANCOR has been manufactured according to the recognized
rules of technology. Nevertheless, there is a risk of personal injury
and property damage if the following basic safety instructions and
the warnings before instructions for action in these operating instruc-
tions are not observed.
Read this instruction manual thoroughly and completely before
using the ANCOR.
Keep the instruction manual so that it is legible. Ensure that it is
accessible to all users at all times.
Always pass on the ANCOR to third parties together with these
operating instructions.
2.1 Intended use
The ANCOR is an acoustic device for active noise reduction in
closed vehicle cabins and is mounted on the headrest of the vehicle
for operation.
The ANCOR may only be used by competent persons and in the
industrial or commercial sector.
The ANCOR may only be used in construction and land vehicles that
recalm GmbH considers permissible and stored as a configuration
setting in the ANCOR app.
In order to ensure effective use, the ANCOR must be configured
before operation for the respective vehicle variant on which the de-
vice is used.
The operating conditions specified in the technical data must always
be complied with.

Important safety instructions
ANCOR V1.0 | 05.2021 Page 10 of 59
Noise reduction by means of the ANCOR is only possible in a limited
range of frequencies and sound pressure levels, see section "Field of
Applicationin chapter "3Specifications".
The ANCOR may only be used together with the approved parts
from the scope of delivery.
The intended use also includes that these operating instructions and
in particular the chapter "2Important safety instructionsare read and
understood in full.
2.2 Non-intended use
Any improper use is prohibited. A non-intended use shall be deemed
to be if:
•the ANCOR is used differently from that described inIntended
use"2.1 Intended use",
•the ANCOR is used under operating conditions which differ from
those described in these instructions,
•of the ANCOR or parts of the scope of delivery are converted or
technically modified.
If the ANCOR is not used as intended, all warranty claims expire.
The manufacturer is not liable for damage to the ANCOR or for per-
sonal injury caused by improper use.

Important safety instructions
ANCOR V1.0 | 05.2021 Page 11 of 59
2.3 Qualification of users
The activities described in this owner's manual require knowledge of
the functioning and structure of the vehicle on which the ANCOR is
used. Therefore, in order to ensure operational safety, these activi-
ties may only be carried out by a person who is sufficiently instructed
in handling the vehicle and, if necessary, safety precautions and who
has a suitable driving license.
The ANCOR may only be assembled, put into operation and operat-
ed by persons who have familiarized themselves with the use of the
ANCOR and the associated dangers on the basis of these operating
instructions.
2.4 General safety instructions
Be sure to follow the instructions in this owner's manual in order
to exclude hazards and avoid damage.
Carry out assembly, commissioning and cleaning work as well as
possible troubleshooting at the ANCOR only when the vehicle is
switched off.
Use the ANCOR and all supplied components only in technically
perfect condition and exclusively in the performance range speci-
fied in the technical data (see Chapter 3).
Do not use the ANCOR in explosive or corrosive environments.
Do not expose the ANCOR to radiation, e.g. microwave, UV
,laser or X-ray radiation.
Protect the ANCOR from damage caused by the ingress of solid
foreign bodies or liquids and from fiber flight.
If the vehicle is not in operation for a long time, disconnect the
ANCOR from the power supply. Depending on the vehicle vari-
ant, the on-board voltage socket is supplied with voltage even
when the ignition of the vehicle is switched off.

Important safety instructions
ANCOR V1.0 | 05.2021 Page 12 of 59
Maintenance and repair work on the ANCOR is not carried out
independently. This work may only be carried out by recalm-
Service.
Ensure that the driver's field of vision remains sufficiently illumi-
nated on all sides even after the ANCOR has been installed. Use
devices for indirect vision on the vehicle, e.g. reversing cameras
or mirrors.
If the driver's seat is rotated or the position of the backrest is
changed, collisions may occur between the mounted ANCOR
and parts of the vehicle cabin. The vehicle operation can be trig-
gered accidentally. Avoid collisions within the vehicle cabin as
well as unwanted operation and starting the vehicle.
Do not hold on to the ANCOR when entering the vehicle, as this
can lead to damage to the device.
In the event of severe weather or strong winds, noise and
measurement errors may occur on the A2B sensors and on the
microphones of the ANCOR. In this case, do not use the AN-
COR.
Ensure that the speakers and microphones on the device frame
are not obscured by garments or other textiles.

Important safety instructions
ANCOR V1.0 | 05.2021 Page 13 of 59
2.5 Work on electrical equipment
Any modifications to the electrical equipment of the device may only
be made by the recalm service.
The device may only be opened by the recalm service.
Regularly check the ANCOR and the supplied components for
obvious defects, e.g. loose bindings or damage to the insulation.
In case of defects in the electrical equipment, disconnect the
power supply from the ANCOR and contact the recalm service.
Never remove or damage the seallabel at the service interfaces
of the ANCOR. The use of the service interface is reserved for
the recalm service.
2.6 Behavior in an emergency
Malfunctions or dangerous situations may lead to an immediate risk
of injury to persons or to a risk of damage to the ANCOR or other
devices in the working environment.
If necessary, stop the vehicle and put it out of service.
Disconnect the ANCOR from the power supply.
If necessary, leave the vehicle and seek help.
Have malfunctions eliminated by the recalm service.
2.7 Behavior under increased noise
pollution
In rare cases, the sound pressure level of the interference source
can be increased by a malfunction of the ANCOR. Sound pressure
levels of up to 105 dB(A) can be emitted. If a person is exposed to
such noise exposure for more than 5 minutes, there is a risk of per-
manent hearing damage.

Important safety instructions
ANCOR V1.0 | 05.2021 Page 14 of 59
Be careful not to expose yourself to noise pollution for more than
5 minutes. If the problem cannot be eliminated by the following
action steps, leave the vehicle cabin and move away from the
sound source.
If the ANCOR does not deactivate the ANC automatically, deac-
tivate the ANC manually via the button on the device frame or
via the ANCOR app (see Chapter 8.1
Re-enable the ANC.
If the malfunction persists:
Deactivate the ANC again and disconnect the ANCOR from the
power supply.
Contact the recalm service.
