should check the Galaxy router label before power on.
Galaxy router should be powered by the AC adapter supplied by Hongdian.
Hongdian will not guarantee Galaxy router performance if it is powered by
any other unqualified AC adapter.
Connect antenna properly before power on.
2.6 Check the Mobile Network
Connect all signal and power cables, and double check it, connect antenna,
insert a valid SIM or UIM (depends your router type and network) and switch on
power. Galaxy H7921 router “RUN” LED will light up. If “RUN” LED is flashing, it
means the Galaxy is working normally. If the “LINK” LED is flashing, it means
there are data stream input/out over router data port. If the “NET” LED lights up,
it means that the Galaxy router has found and logged on mobile network.
(More information refer to Chapter 4)
All cables should be connected correctly before switch on.
Antenna should be connected properly before switch on, otherwise it may
cause radio module problem.
