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 (connect I/O cable).
b. When a received message is printed out the receive memory is erased, but sending or printing
out a message from image memory does not erase image memory. The message remains in image
memory until replaced by another message. The message in image memory can be retrieved any time
by loading output copy on the drum and pressing the SELF-TEST switch.
c. To abort and erase a message in receive memory in order to receive a higher priority, if the
RCV push button has been pressed to start printout, the RCV push button is again pressed momentarily
then released. If the RCV push button has not been pressed, set MODE/DATA FORMAT switch to
MODE A then back to the MODE B selection. The RCV indicator goes out indicating no data in
memory.
d. Do not print out without paper and carbon loaded on the drum.
e. Burst transmission may be received into receive memory while loading a message into the
image memory, except when using gray shades.
f. While printing a message from either receive memory or transmit memory, no other
functions can be performed.
g. When operating with a NATO machine, NATO STD/ALT LDF switch is set to NATO STD;
HI RES LO SP/HI SP LO RES switch is set to HI RES LO SP; and GRAY B/W switch is set to B/W for
loading message, sending, and receiving.
h. If the message does not print out when the RCV push button is pressed, check to make sure
the STOP/START margins are correctly positioned.
i. If the ERROR light flashes during a receive operation, it could be an indication that
communication is lost or the transmit station aborted the message.
j. If the ERROR light remains on longer than 6 seconds after turning on the LDF indicating a
fault in the memory function, the LDF may still be operated in Mode A.
