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

- 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.

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.
