Electrostatic Discharge (ESD) Protection
Electrostatic discharge occurs when electronic components are improperly
handled and can result in intermittent failure or complete damage adversely
affecting an electrical circuit. When you remove and replace any card from a frame
always follow ESD-prevention procedures:
• Ensure that the frame is electrically connected to earth ground through the power cord
or any other means if available.
Wear an ESD wrist strap ensuring that it makes good skin contact. Connect the
grounding clip to an unpainted surface of the chassis frame to safely ground unwanted
EST voltages. If no wrist strap is available, ground yourself by touching the unpainted
metal part of the chassis.
• For safety, periodically check the resistance value of the antistatic strap, which should
be between 1 and 10 megohms.
• When temporarily storing a card make sure it is placed in an ESD bag.
• Cards in an earth grounded metal frame or casing do not require any special ESD
protection.

Cautions for LCD and TFT Displays
Excessive usage may harm your vision. Rest for 10 minutes for every 30 minutes of
usage.
If the LCD or TFT glass is broken, handle glass fragments with care when disposing
of them. If any fluid leaks out of a damaged glass cell, be careful not to get the liquid crystal
fluid in your mouth or skin. If the liquid crystal touches your skin or clothes, wash it off
immediately using soap and water. Never swallow the fluid. The toxicity is extremely low
but caution should be exercised at all times.
