## Preface
|
|

|
|
As a general rule: **don't disassemble any of the modules, ever!** This also applies to experienced VOC people!
|
|
|
|
Everything which needs to be accessed can be reached without violence, especially in the lectern module.
|
|
|
|
## Lecture Module
|
|
|
|
### No Signal at Projector
|
|
- Try another HDMI cable
|
|
- Try to use the projector without the lectern module
|
|
- If nothing helps, you can extend the tray all the way and use different ports
|
|
|
|
### No Audio from the Speaker Laptop
|
|
- Turn on the correct audio source on the ATEM mini:
|
|
* 3.5mm jack: Turn on "MIC 1"
|
|
* HDMI audio: Turn on input 1 ("ON" button is shining red or "AFV" is enabled)
|
|
- Other inputs should be off when not needed
|
|
|
|
|
|
|
|
### Noise/ Humming from the Speaker Laptop/ Lectern Module
|
|
- Turn off the 3.5mm jack input "MIC 1" on the ATEM mini 
|
|
|
|
### Fully Extend the Tray
|
|
The lectern module's tray has some cable ties as stoppers which prevent it to be fully extended.
|
|
If the tray is pulled out too much, the cables to the I/O panel will probably get dislodged and **will cram up between rack tray and network switch**!
|
|
So do not pull out the tray more than needed!
|
|
|
|
In case you need to reach the additional ports (HDMI and secondary SDI) of the UpDownCross, you can get over the stoppers with these steps:
|
|
|
|
- Pull tray out until stoppers are reached
|
|
- Place your hands with 4 fingers below the tray and the thumb on top 
|
|
- Press up next to the cable tie stopper until it goes past the I/O panel below
