Calibration
5.3.4
Manual One Touch Commissioning (BUC calibration)
When the modem starts up for the first time it will automatically register with the BUC
and perform P1dB compression on multiple frequencies and thereafter register with the
Inmarsat network. During the P1dB compression the antenna will point away from the
satellite and transmit on 950 MHz to 1950 MHz in 50 MHz steps. The ACU will show
BUC calibration on the DASHBOARD and the ACU display. This may take up to 10
minutes.
If a new cable calibration is made, the ACU displays the alarm BUC calibration
outdated. Then you must make a manual One Touch Commissioning.
To make a manual One Touch Commissioning (OTC) for the modem, do as follows:
Important
1. Connect a PC to LAN1.
2. Enter the web interface (via Firefox browser) and go to SERVICE > Modem.
3. At Modem access click the link.

WARNING! For your safety: Active RF transmission may occur during an
OTC procedure. Software updates may also occur, yet the system is in
receive-only mode during such auto-updates.
You must use the Internet browser Firefox.
