Static Electricity, ESD, and Your palmOne™ Device
Electrostatic discharge (ESD) can cause damage to electronic devices if discharged into the device, so you
should take steps to avoid such an occurrence.
Description of ESD
Static electricity is an electrical charge caused by the buildup
of excess electrons on the surface of a material.
To most people, static electricity and ESD are nothing more than annoyances. For example, after walking over
a carpet while scuffing your feet, building up electrons on your body, you may get a shock -- the discharge
event -- when you touch a metal
doorknob. This little shock discharges the built-up static electricity.
ESD-susceptible equipment
Even a small amount of ESD can harm circuitry, so when working with electronic devices,
take measures
to
help protect your electronic devices, including your
palmOne
™
device, from ESD harm. While palmOne has
built protections against ESD into
its products, ESD unfortunately exists and, unless neutralized, could build
up to levels that could harm your equipment. Any electronic device that contains an external entry point for
plugging in anything from cables to docking stations is susceptible to entry of ESD. Devices that you carry
with you, such as your device,
build up ESD in a unique way because the
static electricity that may have
built
up on your
body is automatically passed to the device. Then,
when the device is connected to another device
such as a docking
station, a discharge event can occur.
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
palmOne is
that you take this precaution before connecting your device to your computer, placing the device 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.
