If there's no tech crew and you need to set up everything yourself, its all the more reason to arrive early and double check everything. Even experienced speakers who've long ago overcome the terrors of public appearances know that its smart to arrive early, to ensure everything is in place, that the tech guys are clued up and that you microphone won't squeal and your slides won't freeze.
2) To get a different perspective
Have a seat in the audiences seats and take a moment to visualize yourself standing behind the lectern in the front of the room. Now imagine what you're going to look like to the audience.
It's good to check out the view from the back of the room, if only to help you realise how much enegry you'll need to be projecting when you're standing on the stage, to keep these guys in the back interested.
Not everyone is going to be as excited about, and committed to your talk as you are, so its good to see things from the audience's perspective and realize that you might need to come across stronger, bolder and with more vigor in order to maintain everyone's focus in the room.

Here's another simple tip you can add to your confidence-building arsenal. Like most of these tips on how to overcome stage fright, its practical and easy to implement. It just requires a little extra planning (and perhaps getting up an hour or two earlier):
Arrive early at your venue and get to know the room you'll be speaking in.
It's simple, but often neglected. And yet, it has a calming effect on you system, knowing that your speaking in a more familiar place. If you're scheduled to speak at 10am, arrive at nine (or eight if you're like me). Then have a walk around the room, sit in the audiences seats, stride across the stage, stand behind the lectern and maybe even take a minute or two to practice your voice protection from the podium.
Arriving at the last minute in a place you've never seen before, and speaking on a stage you've never walked on, adds unnecessary stress to the whole performance, since there are now additional variables, more unknowns that you're unsure of.
So together with, getting to know the audience, walking around in the room you'll be speaking in will add some confidence to your repertoire.
Venue Scouting & Confidence
Here are two other important reasons why, apart from knowing how to overcome stage fright, you need to know the room you'll be speaking in:
1) To double-check your technology
When technology fails you in the middle of your speech, it can be embarrassing. Most audiences are usually very forgiving of this sort of thing, but it still pays to try and eliminate as many glitches as possible.
So if the room or event youre speaking in has a tech crew, be sure to meet up with them for a quick 'dress-rehearsal' before the event. Wear the microphone, use the remote, check your slides and make sure everything is in order.
