Precautions against ESD
Make sure to discharge any built-up static electricity from yourself and your electronic devices before
touching an electronic device or connecting one device to another. The recommendation from Palm is that
you take this precaution before connecting your handheld to your computer, placing the handheld in a cradle,
or connecting it to any other device. You can do this in many ways, including the following:
• Ground yourself when you’re holding your mobile device by simultaneously touching a metal surface that
is at earth ground. For example, if your computer has a metal case and is plugged into a standard three-
prong grounded outlet, touching the case should discharge the ESD on your body.
• Increase the relative humidity of your environment.
• Install ESD-specific prevention items, such as grounding mats.
Conditions that enhance ESD occurrences
Conditions that can contribute to the buildup of static electricity in the environment include the following:
• Low relative humidity.
• Material type. (The type of material gathering the charge. For example, synthetics are more prone to static
buildup than natural fibers like cotton.)
• The rapidity with which you touch, connect, or disconnect electronic devices.
While you should always take appropriate precautions to discharge static electricity, if you are in an
environment where you notice ESD events, you may want to take extra precautions to protect your electronic
equipment against ESD.
