READOUT INDICATOR
AND TELEPRINTER
The readout indicator provides an identical visual
readout of the data displayed on the front panel of the
receiver-processor. The readout indicator is usually
located at a site some distance from the receiver-
processor.
The teleprinter provides a permanent record of
displayed data. The printouts for modes 01 and 03
occur every 15 minutes or as selected by the operator.
A printout also occurs each time a display mode is
elected and when satellite fix data is received.
One final note on the AN/SRN-19 system. You
must “tell” the equipment where it is when it is
initialized. You must also enter information on
antenna height before the system can provide an
accurate fix.
You can find specific information on the
AN/SRN-19(V)2 in the shipboard operations and
maintenance manual for this navigation set.
