You do not need to move the rig in order to calibrate the compass. Also, the compass will learn over

time to become more accurate.

When you save this setting, the dish will perform a compass calibration, which will move the dish and

take couple of minutes. The dish will not stow after it performs a calibration.

0 The Transmitter is not connected

to the receiver

This is an older code for a DW4000 or DW4020 system.

The transmitter has been

disabled by the Network

Operations Center

This condition occurs when the transmitter is not enabled. A transmitter may

be disabled for short periods of time by the NOC for service or

troubleshooting. It may also be disabled if the user discontinues the satellite

service. If this condition persists, it can only be corrected by requesting that

the unit be enabled.

The transmitter has been

placed in test mode by the

Network Operations Center

This status requires no user action and this test usually completes in 15

minutes or less. This condition occurs when the NOC places the transmitter

into special transmission modes to measure the performance of the

transmitter. When in this mode, the unit is unable to transmit normal user

data to the NOC.

The transmitter is locking to

the receive carrier

This condition occurs during initial startup or when the receiver is locking to

the receive signal. It is normal for this condition to persist for up to 10

seconds. If this condition persists for more than 10 seconds, try

disconnecting and reconnecting the receiver coaxial cable and wait 10

seconds. If the situation still persists, then the Indoor Transmit Unit may

need to be replaced.

The transmitter is not

responding to commands

sent from the receiver

This condition indicates that something is not operating properly in the

Receive/Transmit Unit configuration. Perform the following actions to

attempt to recover from this condition:

• Verify that the Indoor Receive and Transmit Units are securely connected

with a 25-pin parallel cable.

• Reset the IRU by unplugging the IRU power cord from the wall socket and

then plugging the power cord back into the wall socket. This will reset the

Indoor Receive and Transmit Units. This condition could also be caused if

the power supply is faulty. If this condition cannot be resolved by following

the steps listed above, then you may need to replace the power supply, the

Receive/Transmit unit cable and/or the Transmit Unit.

The transmitter is not locked to

the network timing

No action is necessary if this condition occurs from time to time and quickly

resolves itself. If this issue persists, it is likely due to a NOC-related service

issue. The condition may also be due to Indoor Transmit Unit failure; in rare

cases, the Transmit unit may fail and may have to be replaced.

The transmitter is not available

because the receiver is not

detecting a signal or is not

locked to the correct network

Check your receive signal. This condition occurs when the Indoor Receive

Unit is not receiving a good signal. The receiver must be locked to the

correct network in order for the transmitter to operate. If your receiver is not

locked (no signal) or is locked to the wrong network, the transmitter is

unable to transmit data. Please verify that you have a good signal strength

by going to the Receive Statistics page. This could also be caused by

inclement weather.

The transmitter is not available

because the satellite receiver

is not tuned for normal

This condition occurs when the transmitter is disabled for safety reasons. If

this happens during installation or commissioning, the installer will close the

Antenna Pointing program and resolve the condition.
