How do I turn off the flash off my digital camera?

It's an Olympus.
5.0 Megapixel
12x optical & digital
Shooting 19 modes
Movie mode with audio
3x Optical Zoom

Help!

The model number would be helpful so would the manual. There is usually a button with a lightning bolt that's the flash setting sometimes you have to push it several times

Read the manual. If you don't have a manual, Google for one.
