Applies To

Pulse models
Any CommBox screen with whiteboarding capability

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.
