IMPORTANT INFORMATION
If the unit is not positioned in a stable location, it can be potentially hazardous due to falling. Many injuries, particularly to children, can be
avoided by taking simple precautions such as:
• Using cabinets or stands recommended by the manufacturer of the unit.
• Only use furniture that can safely support the unit.
• Ensure the CTOUCH interactive display is not hanging over the edge of the supporting furniture.
• Do not place the CTOUCH interactive display on tall furniture (for example, cupboards or bookcases) without anchoring both the
furniture and the CTOUCH interactive display to a suitable support.
• Do not place cloth or other materials between the CTOUCH interactive display and supporting furniture.
• Do not let children climb on furniture to reach the CTOUCH interactive display or its controls.
• Do not use immediately after moving from a low temperature to high temperature environment, as this causes condensation, which
may result in fire, electric shock or other hazards.
• To avoid possible condensation it is recommended to not use the device within 24 hours after its arrival.
Warning:
To prevent the spread of fire, keep candles or other open flames away from the CTOUCH interactive display.

IMPORTANT SAFETY PRECAUTIONS
ABOUT LOCATION / ENVIRONMENT
Do not use in hot and cold rooms (locations)
• When the unit is used in rooms (locations) with low temperature, the picture may leave trails or appear slightly
delayed. This is not a malfunction. The unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight to near a heater or in high
humidity, as this may cause the cabinet to deform and the screen to malfunction and affect the CTOUCH interactive display’s performance.
• Environment condition:
Operating temperature: 5°C – 35°C
Operating humidity: 20% – 80% (no moisture condensation)
Storage temperature: -15°C – 45°C
Storage humidity: 10% – 80%
Atmospheric pressure: 86 kPa ~106 kPa
ABOUT AFTER-IMAGE
The extended use of fixed image program material can cause a permanent after-image on the screen. This background image is viewable on normal programs
in the form of a stationary fixed image. This type of irreversible screen deterioration can be limited by observing the following steps:
A. Reduce the brightness/contrast setting to a minimum viewing level.
B. Do not display the fixed image for extended periods of time.
C. Turn the power off when the display is not in actual use.
Important Information Regarding Use of Video Games, Computers, Captions or Other Fixed Image Displays.
• Do not allow a still picture to be displayed for an extended period of time, as this can cause a permanent after-image to remain on the
screen. Examples of still pictures include logos, video games, computer images, teletext and images displayed in 4:3 mode.
CAUTIONS:
• The permanent after-image on the screen resulting from fixed image use is not an operating defect and as such is not covered by the warranty.
• This product is not designed to display fixed images for extended periods of time.
• It is not advised to put the screen in portrait mode because this will affect the warranty.
CLEANING AND MAINTENANCE

TROUBLESHOOTING
General
Problem Possible Solutions
Some items cannot be accessed • If a setting option appears in grey, this indicates that the settings option is unavailable in current input mode. Some display menu items may be
different when the unit works in different sources.
Remote control command is not working in some
cases • During the timing of USB device detection (i.e. when the CTOUCH interactive display is turned on with USB device connected, or when you
plug in USB device during the working of the CTOUCH), the display may not react on remote control buttons in such case. Wait a moment
before the remote control should function again.
Control buttons do not operate • Disconnect the power cord and wait for a few seconds. Then re-plug the power cord and turn on the unit again
Touch does not work • If you use a Apple-device, please download the Mac-driver from our website.
Fog appear on the screen • For the safety of screens, adding stalinite out of the screens. It is need to keep certain space between two layers for reserving air passages
generate cross-ventilation and for insuring heat dissipation. Fog mainly comes from the temperature difference between the screen and the
external. Moisture streaks congeal when hot air meets the low temperature glass surface The fog does not impact the normal use and it
disappears after several-hour usage.
Screen puts itself in stand-by mode as external
device or Easy Air PC goes in sleeping mode. • Change the energy settings/sleeping-mode of the external device or Easy Air PC.
Note: If your problem is not solved, turn off your unit and then on again.
Cautions: Never attempt to repair a defective CTOUCH interactive display yourself.
