TIP
When removing ink, don’t use Sanford Expo Dry Erase Board Doctor, Sanford
Expo Cleaning Wipes, low-odor Sanford Expo Whiteboard Cleaner
or Windex® glass cleaner, which don’t adequately clean the surface
of your SMART Board V280 interactive whiteboard and can leave
permanent stains.
• If ink remains on your interactive whiteboard for a long period of time, you might
need to scrub the ink with Sanford Expo Whiteboard Cleaner for as long as five
minutes. Although a faint residue might remain, it isn’t usually visible when the
projector is on.
• Remove persistent stains by gently rubbing a paste of baking soda and water
on the screen surface.
• The digital cameras located in each screen corner under the valance
are protected from dust and dirt by protective windows. You only need
to clean the camera windows if your interactive whiteboard is located
in an extremely dusty environment.
• Rotate the valance upwards in its clips to clean the diagonal surfaces of the
camera windows. Gently rub a soft, clean, damp, cotton cloth or cotton-tipped
swab on the windows.
CAUTION
Do not use an abrasive cloth or paper towel to clean the camera windows
because you might scratch the surface.
