Step by step
1. Turn on
- 1Wake the system: press the POWER or ON button on the wall panel, lectern, or display remote.

3. Use
- 1Set volume with the room control first, then your laptop volume (keep laptop near 75%).
- 2Mute video with the BLANK or A/V MUTE button instead of shutting the projector off.
- 3Mics: turn on, check the battery light, and clip the lapel mic about a hand's width below the chin.

4. Turn off
