Writing, drawing, and erasing
The display includes a black pen, a red pen, and two erasers. You can use the pens to write and draw in digital ink on the display, and you can use the erasers—or your palm or fist—to erase digital ink.
The display has magnetic holders for the pens and erasers at the bottom of the display’s frame. Return the pens and erasers to their holders when you’re done with them.
Caution
When you return a pen to the magnetic holder, make sure it’s centered in its holder to keep it from falling and being damaged.

Several people can write or draw on the screen at the same time. Each pen writes and draws in its own color. The Pen ID feature lets you temporarily assign different colors, thicknesses, and other properties to each pen.
Important
Use only pens compatible with SMART Board RX interactive displays.
Note
When a pen is introduced to a display for the first time, it may take a few moments for the pen to pair with the display.
To write or draw in digital ink
Pick up one of the display’s pens.
Write or draw in digital ink on the screen.
Tip
Hold the pen at a 45 degree angle to the display surface.

The RX display features palm rejection: you can rest your hand on the screen while writing and it’s not interpreted as input. You can disable this feature by selecting Settings
SMART
Touch Settings and toggle the feature off.

The pressure-sensitive tips on SMART RX pens provide versatility in presentations and note-taking. The Tool Explorer feature is supported whenever you’re working in SMART iQ. It’s also supported in many Windows applications, including OneNote.
To use pressure-sensitivity
Pick up one of the display’s pens (black or red).
Write or draw in digital ink on the screen. By applying more pressure on the pen, the line becomes thicker. Use less pressure and the line becomes narrower.
To turn pressure-sensitivity off
Go to the Home screen.
- Select Settings
SMART
Touch Settings and toggle the feature off.
Pressure-sensitivity works alongside features such as changing the pen color and properties.
Tip
If the pen tip is not pressed on the display surface before you move it across the display surface, the pen may only draw in black ink. Press you pen to the surface before you begin writing or drawing.
Tool Explorer works best when the pens are separated by at least 4” (10 cm). If the pens are closer than that, you may experience errors or unexpected ink behavior.

You can change a pen’s color with a press of the button. An LED briefly illuminates in the color selected (red, green, blue, or black).

To lock a color, press and hold the button for three seconds. The LED flashes in the selected color three times to indicate it’s locked.
To unlock a color, press and hold the button again for three seconds.
Note
This function is only available with supported SMART apps, including iQ Whiteboard, SMART Notebook, and SMART Ink. It is not available in third-party applications, such as Microsoft PowerPoint and Google Sheets.

If you pick up a pen while viewing a connected computer’s input, the SMART Ink dynamic (floating) toolbar for SMART Ink appears on the screen. You can use this toolbar to temporarily change the pen’s color, thickness, or other properties. You can also access SMART Ink’s other tools, such as screen capture, spotlight, screen shade, and so on.

You can change a pen’s color, thickness, and other properties temporarily using the SMART Ink dynamic (floating) toolbar when you’re viewing a connected computer’s input.
Note
When working in iQ, the pen’s color, thickness, and other properties return to their default settings after the pen is returned to the display’s magnetic pen well. This may take up to 30 seconds.
