TURNING SATELLITE NETWORK ON
The satellite network must be
turned ON to send non-flight
related messages. Since the
VHF network has precedence
over the satellite network in areas
of shared coverage, the VHF
NETWORK must be turned OFF
in order for SATCOM to be the
Active Link. If the VHF network
cannot be received and the SAT-
COM mode is set to ON the sys-
tem will automatically select the
SATCOM mode for transmit and
receive.
