Intrinsic Safety Warning

Warning – Explosion Hazard

• Substitution of components may impair suitability for Class I, Division 2;

• When in hazardous location, turn off power before replacing or wiring modules, and,

• Do not disconnect equipment unless power has been switched off or the area is known to be 

non-hazardous.

Wireless Notices—Usage Cautions

In some situations, the user of the wireless device may be restricted. Such restrictions may apply aboard 

an airplane, in hospitals, near explosive environment, in hazardous locations etc. If you are not certain of 

the policy that applies to the use of this device, please ask for authorization prior to turning on the device.

Static Electricity, ESD, and Your Palm

®

 Handheld

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

Palm

®

 handheld, 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 handheld,

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
