Front Carry: X Strap
When done correctly the straps should create an X on your back.
Cross the right shoulder strap over your back and fasten to the left side buckle. Then cross the left shoulder strap over your back and attach to the right side buckle.
Back Carry: H Backpack Strap
Uncross shoulder straps and re-buckle on other side so that straps can be worn like a backpack.
Ask someone to help you with this position until you are comfortable on your own.
