The transmitter is disabled

test
23
The transmitter is disabled
because a transmit pointing
test cannot be performed
This condition occurs when the transmitter fails a transmit pointing test. This
indicates that the transmitter did not meet the minimum specifications required.
This is likely due to an antenna installation problem. The antenna installer needs
to fine-point the antenna. The transmitter will not transmit until the transmit
pointing test passes.
This condition occurs when the transmitter is required to perform a periodic
background transmit pointing test, but has not been able to perform the test
within the time window required. The transmitter is expected to be in this
condition for no more than two minutes at random periodic intervals. This
condition can also occur after the transmitter is first powered on after it has been
powered off for more than a day. If the unit remains in this condition for more
than two minutes, then the automated transmit pointing components in the NOC
are likely experiencing problems. This condition should clear in a few minutes.
This condition occurs when the transmitter cannot perform the transmit pointing
test when initially installed or when the transmitter is required to range. The
condition indicates that the NOC components needed to perform the transmit
pointing test are not operational.
