Palm 750 Cell Phone User Manual

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
device, from ESD harm. While Palm 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 Palm
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 Palm is that you take this precaution
before connecting your Palm 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 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
0ectricity, 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.
