Warning
 Tighten the antenna connector gently with your hand – never use a
wrench!
 Being a source of radio frequency emissions, the 2N ® BRI Enterprise / BRI
Lite antenna should not be very close to the human body. The health
hazard is higher than with mobile phones as, in general, gateways shared
by multiple users show a very high traffic.
Note
 The antenna has a sufficient gain for a trouble-free operation under normal
conditions. If the signal is poor or you want to place your antenna away
from 2N
® BRI Enterprise / BRI Lite, you can use an antenna with an SMA-
connector terminated cable. The antenna should be mounted vertically.
 Refer to S. 8, Technical Parameters, for the antenna parameters.
Power Supply Connection
Use only the power supply adapter included in the delivery. Make sure that the electric
distribution network voltage is in compliance with the data on the supply adapter plate
before plugging the adapter and that the antenna is connected properly. If you
connect the power supply without having connected the antenna, the GSM module
transmitter may get damaged. Plug the supply adapter into the mains socket and only
then connect the adapter connector to the gateway. Refer to the status indicators.
