There are a few controls and some etiquette that may be useful to know about. An example of the control bar is shown above. You can see more about the appearance on different devices here
When you join the meeting you will be asked whether you want to do so with computer audio or using the telephone. You should almost always elect the “Join with computer audio” option. Once you have done so you should be able to hear others speaking and your microphone will be live.
You will need to ensure that the volume control on your device is set at a normal level for listening. Microphones usually do not need adjusting.
You should be able to see others who have already joined the meeting. The layout on screen of the other participants can be varied. You should usually select Speaker View.
Your camera will also be on and you can be seen by everyone else.
Controlling your camera and microphone.
You can decide whether you wish to be seen and heard. There are two controls on the Zoom application usually at the bottom left.
You can click the camera icon to switch it on or off. If it is switched off others will simply see your name rather than your video stream.
You can “mute” or “unmute” yourself by clicking on the microphone. In large meetings it is best for almost everyone to be muted. If a microphone is unmuted then Zoom will try to broadcast any sound from there to everyone. This can get very confusing.
The host can mute everyone and will do so at the beginning of the talk.
