Learning Event 1:
OPERATE LDF IN MODE A
Mode A Operating Procedures. Mode A operating instructions for the LDF consist of send and
receive operations. The LDF is in Mode A when the MODE/DATA FORMAT switch (Figure 6) is
selected to the MODE A position. Mode A self-test operations are described in paragraph 2-6.3 of TM
11-5815-615-10. Except for self-test, the procedures describe the action required by two operators: one
at the sending LDF, and one at the receiving LDF. The following should be noted during operations:
a. Sending and receiving LDFs have been installed and interconnected as described in Chapter
2, Section II, of TM 11-5815-615-10.
b. If the drum does not accept the document when the RCV or SEND push buttons are pressed,
check to make sure the STOP/START margins are correctly positioned.
