TROUBLESHOOTING TABLE (Table 2-2)

TM 11-5815-238-20

NOTE

The procedures in Table 2-2 assume that the teletypewriter is connected to a signal line or the local

test circuit (see para 2-11), that a good fuse is properly inserted in the fuse holder and that paper

tape has been properly loaded in the teletypewriter.

This manual cannot list all troubles that may occur, nor everything to check, nor all possible procedures to correct

troubles listed. If trouble is not listed in Table 2-2 or is not corrected by the procedures under CORRECTIVE

ACTION, notify your supervisor or next higher level of maintenance.

Set KEYBOARD switch to SEND position.

Set SELECTOR switch to position 3 (LOCAL REPUNCH).

TT-76(*)/GGC teletypewriter transmitter contacts are now placed in series with the selector magnet and a local dc

supply. TT-699(*)/GGC teletypewriter contacts are now placed in series with each other and the input from the line

transmitter module. The local machine reperforator can now be operated with signals received directly from transmitter-

distributor or key board transmitter.

NOTE

If the trouble still exists after Troubleshooting, check for it in the line circuit or at the distant

teletypewriter.
