Thank you both of you. Now I clearly understood, how to handle INS.
I think both of your dedication to INS, MAKE FEEL BAD, I decided to learn to operate  INS navigation system.

Now one more question I have:

When green light appears ,INS mode selector should be turn to NAV mode.

To connect INS to A/P:
1-Do you turn just HDG selector of A/P and also push down the INS NAV switch on cockpit pane.

Or,

2-Do you just turn A/P mode selector to NAV?
