		power. The satellite transmitter conducts ranging as needed to ensure that it can
		communicate successfully with the Network Operations Center. The ranging
		failure may happen due to the antenna becoming misaligned or if repeated
		attempts to range do not succeed. This condition may also be caused due to
		adverse weather conditions. In rare cases, this may also indicate NOC issues
		but should clear within a few minutes.If the system was operational in the past
		and you see these messages repeatedly, you can try to force range by

		successfully with the Network Operation Center. A possible cause is that the
		transmitter could not achieve enough power to transmit. This is likely caused
		because the antenna is not accurately pointed. However, it may also be a
		transmitter power problem. Check the power supply and make sure that it is Part
		# 1031105-0001.
18	The transmitter is requesting a	This condition can occur during installation when the Antenna Pointing program
	transmit pointing test	on the installation computer requests that the transmitter perform a transmit
		pointing test. This condition persists until the NOC responds that the transmitter
		is either actively performing the pointing test or is queued to perform the test
		when test resources become available in the NOC. This is a normal condition for
		initial installation. The transmitter may also periodically go into this condition for
		short periods of time (less than 5 seconds) to perform periodic transmit pointing
		tests. These periodic tests are performed to ensure that the antenna is pointed
		accurately.
19	The transmitter is queued for a	This condition can occur during installation when the Antenna Pointing software
	transmit pointing test	on the installation computer requests a transmit pointing test and the NOC has
		responded that the transmitter is queued for the next available test time. It may
		also occur when the transmitter is performing periodic background transmit
		pointing tests at the same time that other users on the network have requested
		tests. This is a normal state after initial installation.
20	The transmitter is performing a	This condition occurs when one of the following tests are active:

		perform a transmit pointing test. This condition will persist until the Antenna
		Pointing software exits from the transmit pointing test mode.
		• The DW4020 performs a periodic background transmit pointing test to make
		sure that the antenna is still pointed correctly. This periodic test takes less than
		5 seconds.
		If the problem persists, try power-cycling the DW4020 by unplugging the wall
		outlet and plugging it back in.
