Use the MXC's STATUS key to interrogate a transmitter and display a FAILSAFE message caused
by a transmitter failing a self-diagnostic test. This will identify the source of error through an error
message described in Table 6.1 and Section 6.3.2.1, paragraph
A.
Transmitter self-diagnostics are executed by selecting TEST
from the MXC's CALIBRATE/TEST screen. If the test is
failed, a message is displayed. Refer to Section 6.3.2.1, paragraph A for details.
