Adjusting the Volume

There is a volume control on the top-left side of your iPhone(Shown circled here in red) that controls the ringer volume - each time you press the top of the volume, and the bottom of the button decreases it with each press. When you change the ringer volume using this button, you'll see the volume bar temporarily appear on screen so you can easily see your current volume setting as you adjust it. Although this button controls the ringer volume, it's a "context sensitive control," so once you make a call, it automatically switches to control the volume of your phone call(that way, if you're making your call in a busy place like an airport, you can turn up the volume so you can hear your call), if you're playing a song or a video using the iPod, the button switches to control their volume.
