ATTENTION
The OnCell
3120-LTE-1 is NOT a portable mobile device and
should be located at least
20 cm away from the human body.
The OnCell
3120-LTE-1 is NOT designed for the general pu
blic.
A well
-trained technician is required to deploy the OnCell 3120-
LTE-1 units and safely establish a wireless network.
ATTENTION
Use the antennas correctly!
Wide
-band (2G/3G/4G) antennas are needed when the OnCell
3120
-LTE-1 operates. Make sure that your antenna installation
is within a safety area, which is covered by a
lightning
protection or surge arrest system.
