WLAN antennas
Screw the two supplied
WLAN antennas onto
the connectors Ant1
and Ant2. Depending
on how the antennas
are to be used, 'Antenna
Grouping' may need to
be configured in order to
provide the desired MIMO
behavior.

No WLAN network defined or WLAN
module deactivated. The WLAN module is
not transmitting beacons.
Green on,

Green inverse
flashing
Number of flashes = number of connected
WLAN stations and P2P wireless connec-
tions, followed by a pause (default).
Alternatively the frequency of the flashing
can indicate signal strength over the
defined P2P link or the signal strength
between the access point and the device
operating in client mode.

When working with separately purchased antennas, please ensure you
do not exceed the maximum permissible transmission power. The system
operator is responsible for adhering to the threshold values.
Antennas are only to be attached or changed when the device is switched off.
Mounting or demounting antennas with the device switched on may cause the
destruction of the WLAN module!
