Quick Tip: Leave Your BlackBerry off the Set, Podium, etc.
Have you ever listened to a speech or watched a video and heard a strange crackling sound? Like radio interference?
Well, chances are it is the speaker’s BlackBerry (which is a radio device at heart). When you receive a message on a BB, it often creates signal interference with nearby audio equipment used for recording or capturing your voice. For recordists and audio purists, it is annoying and likely distracting for most folks if it happens a lot during a session. iPhone, Treo and other smartphone users don’t seem to have this issue.
So, put that BB aside when you are on-camera or speaking, and let your message come through loud and clear.
