Optional:  
WAN

Use a cable with 
the green-colored 
connectors to con-
nect the interfaces 
ETH2 to your WAN 
modem.

Optional:  
Wireless LAN antennas 

Screw the two supplied 
WLAN antennas onto 
the connectors WLAN1 
and WLAN2. Depending 
on how the antennas 
are to be used, 'Antenna 
Grouping' may need to 
be configured in order to 
provide the desired MIMO 
behavior.

Optional:  
siM card

Slide the SIM card into the slot using the 
marker to ensure that the card is the right 
way round.
Ensure that the SIM card clicks into place 
on insertion. To remove the card from the 
device again, press the card lightly into 
the device. Let go to release the SIM card 
from the slot.

Optional:  
LAN

Use a cable with 
the kiwi-colored 
connectors to con-
nect the interfaces 
ETH1 to your PC or 
a LAN switch.

3g antennas or 
gps antenna

Screw the two supplied 
cellular antennas onto the 
connectors 3G Aux and 
3G Main. 
Alternatively screw 
the free available GPS 
antenna onto the connec-
tors 3G Aux (see included 
voucher).
