Step-by-Step Instructions
Step 1
Use the CommBox eraser
-
All Classic V3X, S4, and S5 screens include a CommBox eraser designed for use with the whiteboard and annotation apps.
-
Simply hold the eraser flat against the screen and move it across the area you want to clear.
Step 2
Use any flat object - including your hand!
-
Don’t have the eraser handy? You can use any flat object over 10cm wide — like a book, soft cloth, or even the back of your hand.
-
Just ensure the surface is clean to avoid scratching the screen.
💡 Tip: The larger the surface area, the more efficiently you can clear content from the screen.
Troubleshooting / What to Do If It Doesn’t Work
-
Make sure you are using a compatible app like the whiteboard or annotation tool.
-
If erasing doesn’t respond, try restarting the app or screen.
