Before calling 3M Touch Systems, try the suggested actions that are appropriate to the problems you are experiencing with the monitor. You may also want to consult your video card user’s manual for additional troubleshooting advice. Maintaining Your Touch Monitor To maintain your display and keep your monitor operating at peak performance: • Keep your monitor and screen clean. • Adjust the monitor video controls. Refer to Chapter 3 for more information. • Do not install the display in a place where ventilation may be hindered. Always maintain adequate ventilation to protect the display from overheating and to ensure reliable and continued operation. Touch Screen Care and Cleaning The touch screen requires very little maintenance. 3M Touch Systems recommends that you periodically clean the glass touch screen surface. Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning agent for your touch screen. You can also use straight isopropyl alcohol. In addition, 3M Screen and Keyboard Cleaner CL680 has been tested and approved for this use. CAUTION To avoid the potentially hazardous situations associated with the use of alcohol or other solvents which may result in minor or moderate injury or property damage: • Follow all instructions and recommendations in the manufacturer's Material Safety Data Sheet and product label. • Be sure to follow solvent manufacturer's precautions and directions for use when using any solvents • It is important to avoid using any caustic chemicals on the touch screen. Do not use any vinegar-based solutions. • Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths. • Always dampen the cloth and then clean the screen. Be sure to spray the cleaning liquid onto the cloth, not the screen, so that drips do not seep inside the display or stain the bezel. • Always handle the touch screen with care. Do not pull on or stress cables.
