13 The transmitter is unable to range because it
cannot communicate with the HX GTWY Ranging is the automated process of adjusting
satellite transmitter timing and power. The
satellite transmitter performs ranging as
necessary to ensure that it can communicate
successfully with the HX GTWY. This condition
can indicate any of the following:
• The GTWY is not receiving ranging
information from the transmitter. This may
indicate a transmit problem at the GTWY and
should resolve itself within a few minutes.
• The transmitter is unable to achieve enough
power to send ranging information to the
GTWY.
• The transmitter is sending incorrect timing
data because incorrect ZIP code or incorrect
latitude/longitude information was entered
during installation.
• The outdoor transmitter unit (ODU) is not
operating properly or is not properly
connected to the remote terminal. Ensure
that the transmit cable is securely fastened
to the satellite out connector.
14 The transmitter is not available because
ranging has failed This condition indicates that the transmitter is
not operational due to a ranging failure.
Ranging is the automated process of adjusting
satellite transmitter timing and power. The
satellite transmitter performs ranging as
necessary to ensure that it can communicate
successfully with the HX GTWY. A ranging
failure may occur due to antenna misalignment
or after several failed ranging attempts. This
condition may also be caused by adverse
weather conditions. In rare cases, this
condition may also indicate GTWY issues but,
in such cases, should clear within a few
minutes. For repeated messages of this type
on a system that was previously operational,
try to force ranging by performing the
Connectivity Test.
15 The transmitter is waiting for a ranging request
to be processed by the HX GTWY This condition occurs when the system is busy
adjusting power and timing for other users.
This process may take up to a minute or more.
16 The transmitter is waiting for a transmit request
to be processed by the HX GTWY This condition occurs when the system is
unable to provide transmit bandwidth. This
occurs when a large number of users sign on
simultaneously. This condition should clear
itself within a few minutes.
