1. Don’t carry on with loud or long conversations in office. If you must speak, limit it to a few words spoken in a low voice, or move to another room.

2. You may think your ringtone is cool, others might not. Consider switching to a conventional tone and keeping it on minimum volume.

3. Better than volume level 3, switch your cell phone to “mute” and, instead of irritating everyone with your chosen ringtone, let it vibrate in your pocket.

4. Allowing yourself to be overheard while discussing private business on a cell, is at best seen as showing off and, at worse, gives away important personal data.

5. If you really have to make a long call, it is good manners to excuse yourself and do it in a non-quiet area.

6. When you want to change your ringtone, or test the volume level of the ringtone, do it at home, unless you want to risk your phone being snatched away or stamped on.
