E-P3 vs. SB600 off camera

Hi everyone,

I am new to micro four thirds and new to Olympus. I recently sold my DSLR gear but kept the SB600, lightstand and umbrella.

How can I trigger an S600 remotely from the E-P3?

I am looking for a cheap option since I don' do a lot of flash.
Is there a way that the pop up flash could trigger the SB600?

Many thanks!
