After connecting the cable
to the device, turn the
bayonet connector 90°
clockwise until it
clicks into place.

Use only the supplied
power adapter.

Antennas are only to be attached or changed when the device is switched off. Mounting or
demounting antennas while the device switched on may cause the destruction of the 4G
module!

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, press the card slightly
