Improving your meeting experience

You can do the following things to have the best meeting experience for you and other meeting participants:

Before a meeting

Before the meeting starts, use the following to optimize your meeting experience:

  • Check that your computer, tablet or mobile meets Challo’s minimum specifications
  • For real-time video it is important that your network connection remains stable.
    • If you can, plug your computer into the network.
    • If you can, disconnect from any VPNs.
    • Wireless connections are perfect to use, as long as your connection is consistent and effective.
  • Some laptop microphones pick up background noises or echo, and that can be distracting for other participants.
    • If possible, find a quite place where you can talk and hear other participants.
    • If possible, use a good quality headset and keep the microphone at the correct distance from your mouth.
  • Use the correct type of microphone for your environment:
    • If you join a meeting alone, a microphone with single-direction or cardioid support is ideal.
    • If you join a meeting from a conference room, use a microphone with an omni-directional support, so that people’s voices are heard accurately.
  • Check your lighting
    • Position yourself, or the lights, so that the brightest light source is in front of you. By doing this your face is illuminated and other participants can see you clearly.

Check your devices

When you access a meeting, the best time to find and resolve issues is Before you join, here Challo gives you an opportunity to check your settings.

Initially, Challo requires that your browser has permission to use your microphone and camera.

Challo tries to pick the correct camera, microphone, and speaker; however, you know best.

Before you Join the meeting, take a moment to open your settings and check the following:

  • Select your Camera—Your preview shows you what others see during the meeting.
  • Select your Microphone—If you speak and Challo can hear you, the indicator moves.
  • Click TEST AUDIO to check your speakers are not too quiet or loud.

During a meeting

During a meeting, use the following to optimize your meeting experience:

  • Turn your camera on
    • During meetings, if you look straight at the camera other participants see that you are engaging with them, like you do when you speak to them in person.
    • If you do not use cameras frequently, this can be difficult to learn.
  • Do not forget that your camera is on.
  • If you are in a noisy room, or you are outside, mute your MICROPHONE if you have nothing to say.
  • Be careful if you use a mute on your microphone, Challo cannot determine if you have done this.
  • If you need to move to another location, or have to step away from your meeting, click CAMERA to stop sending video.
  • If you are on a mobile device, try not too move around too much, this can have an effect on your wireless connection transfer rates.

Hold a practice meeting

  • During the meeting say a few words.
  • For example:

Type out three lists of orders.
The harder he tried the less he got done.
The boss ran the show with a watchful eye.
The cup cracked and spilled its contents.
Paste can cleanse the most dirty brass.
The wharf could be seen at the farther shore.
Feel the heat of the weak dying flame.
The tiny girl took off her hat.
