how do you set and align peep sight?

[Unregistered]

I just got my new Martin Sabre compound bow yesterday and I reallly like it. I am very new to use compound bow for hunting (wanted to try something new). Today, I went out target practice and after couple releases, my peep sight went off. I don't know how to set and align it back on. I really need some help here, does anyone know how?

Please help me, bow hunting season is just around the corner.
Thank you very much.
