29 smarttech.com/kb/170800
Preventing condensation
The interactive flat panel screen contains layers of glass that can collect condensation, especially
in the following conditions:
l
Temperature extremes with high humidity
l
Rapid changes in humidity, which can occur when you operate the product near water (such as
a pool, kettle or air conditioner ventilator)
l
Direct exposure to sunlight
l
Cold air output from an air conditioner towards the bottom of the interactive flat panel.
To evaporate condensation from the interactive flat panel
1. Remove the humidity source from the interactive flat panel, if possible.
2. Turn off the interactive flat panel.
3. Remove any moisture from the interactive flat panel with a smooth, dry cloth.
4. Leave the interactive flat panel turned off for 48 hours.
Cleaning the touch sensors
The interactive flat panel uses infrared (IR) transmitters and sensors around perimeter between the
screen and the frame. Dust buildup on the protective plastic can impair touch performance. Inspect
these areas for dust and clean them every week.
CAUTION
l
Do not use compressed air to clean the sensors or borders.
l
Do not use water or cleaning agents to clean the touch sensors.
l
Don’t apply too much pressure when cleaning the interactive flat panel because you can
damage the plastic causing performance issues.
To clean the IR transmitters and sensors
1. Using a clean lint-free cloth, gently wipe the protective plastic between the screen and the
frame around the perimeter the interactive flat panel screen.
2. If dirt still remains, use 50% isopropyl alcohol (IPS) solution to clean the protective plastic
between the screen and the frame.
