Perform Cold Start Net Opening (Special Operator Task 3)

DESCRIPTION

Operators will be required to perform this special task only if the NCS

elects to use the Cold Start net opening procedure. Hot Start is the

more commonly used net opening procedure. Cold Start procedures

require operators to load their radios with COMSEC keys and FH data,

stand by at the prescribed time, communicate with the NCS on the

MAN channel, set RT FCTN to LD, note when ERF is received, and

press STO and channel number to retain data. Any failure in the ERF

process prevents the operator concerned from communicating in the

frequency hopping mode. Because the Cold Start procedure is more

demanding in coordination and operator requirements, units normally

use the Hot Start procedure.
