6. Switch Settings and Initialization.

The following tables provide the necessary switch settings and

communication parameters for interoperability. Initialize the MCS for communication as shown In Table 6-2 Verify

the switch settings for both the radio and the MCS; then establish communication on the net.

For a SINCGARS/VRC-12 net, select channel code 13.

In a hostile or noisy environment, and long communications distances, a data rate slower than 16

kbps is required. Choose 4800, 2400, or 1200 bps as conditions permit. This Is accomplished by

modifying channel code 13 (KY-57 SINCGARS NRZ 16k) as shown in Table 6-2 and saving

Initialization as a new channel code 19 called 'SINCGARS LOW SPEED DATA .

Place radio to standby when doing a system initialization or channel reconfiguration. Turn

function switch to SQ ON after Initialization is complete.

You must clear the COMSEC alarm with a double PTT before proceeding.
