Configuration of the dual antenna solution
3. Go to Setting - Dual antenna page to set the antenna as master in dual
configuration.
B.3.6 To make an OTC for dual antenna systems
1. Make an azimuth calibration with both antenna systems (master and slave) using
manual azimuth calibration mode and one of the GX satellites,
Make sure you
have line-of-sight
..
2. Make a TX calibration for the master antenna system and for the slave antenna
system.
The entire dual antenna system is now ready for OTC.
1. Turn on the modem
power.
The first time the modem is turned on it will perform an OTC both on the master
and the slave antennas. During this process the modem will restart several times
before pointing towards the satellite and establish the link.
2. Be patient. The OTC procedure will take at least 16 minutes.
3. If for some reason you make a TX cable calibration again, the system will request
the operator to initiate a manual OTC procedure. You can start the OTC procedure
from the modem dashboard.

Important
Do not power up the GMU at this point in time.
Important
Interrupting the process before it has completed will cause the
process to restart.
