Operator Tasks, enable a SINCGARS NCS to meet all normal

communications requirements when the unit is in an operational

situation.

tasks without assistance, other than reference to the NCS Pocket

Checks and Services (PMCS) (see Chapter 8) are to be performed prior

to performing operator or NCS tasks.

Summary of Primary NCS Tasks

6.3b.

Transfer Partial COMSEC/FH Data, ANCD to ANCD

PRIMARY TASK 1:

Used to download selected COMSEC keys or FH data elements from

one ANCD to another. This task supplements Special Operator Task 1,

"Transfer COMSEC/FH Data From ANCD to ANCD," which transfers

complete data loads.

Transfer Selected SOI Information, ANCD to ANCD

PRIMARY TASK 2:

Used when less than a complete SOI load is to be downloaded from

one ANCD to another. This task supplements Special Operator Task 2

Alternate, "Transfer Full SOI information From ANCD to ANCD," which

transfers the complete SOI file.

Conduct Hot Start Net Opening

PRIMARY TASK 3:

This is the principal method used for net openings; operators load all

required data and sync time and, at the prescribed net opening time,

call the NCS and enter the secure. FH net.

Conduct Cold Start Net Opening

PRIMARY TASK 4:

This is an alternate method for opening the net. It requires operators to

load COMSEC and FH data, standby to receive an ERF containing sync

time, and properly storing the ERF It requires close coordination and

correct operator actions. It may be used in situations where the NCS

wants all operators to enter the net at the exact same time.

Respond to CUE Calls

PRIMARY TASK 5:

This task is performed whenever the "CUE" message appears in the

NCS's RT display. In that response to a CUE message requires leaving

the operational net, transmitting in SC mode, possibly sending an ERF,

and probably displacing physically to avoid enemy direction finding,

the NCS designates an Alternate NCS to respond to the CUE call.
