ELECTROSTATICALLY SENSITIVE DEVICES

Some semiconductor (solid-state) devices can be damaged easily by
static electricity. Such components commonly are called Electro-
statically Sensitive (ES) Devices. Examples of typical ES devices are
integrated circuits and some field-effect transistors and semicon-
ductor “chip” components. The following techniques should be
used to help reduce the incidence of component damage caused by
static electricity.

1. Immediately before handling any semiconductor component or
semiconductor-equipped assembly, drain off any electrostatic charge
on the body by touching a known earth ground. Alternatively, ob-
tain and wear a commercially available discharging wrist strap de-
vice, which should be removed for potential shock reasons prior to
applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices,
place the assembly on a conductive surface such as an ESD mat, to
prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES
devices.

4. Use only an anti-static solder removal device. Some solder re-
moval devices not classified as “anti-static” can generate electrical
charges sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electri-
cal charge sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective pack-
age until immediately before you are ready to install it. (Most re-
placement ES devices are packaged with leads electrically shorted
together by conductive foam, aluminum foil, or comparable con-
ductive material.)

7. Immediately before removing the protective material from the
leads of a replacement ES device, touch the protective material to
the chassis or circuit assembly into which the device will

be in-

stalled.

Caution: Be sure no power is applied to the chassis or circuit, and
observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replace-
ment ES devices. (Otherwise, seemingly harmless motion, such as the
brushing together of your clothing or the lifting of your foot from a
carpeted floor, can generate static electricity sufficient to damage
an ES device.)

REGULATORY INFORMATION

This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures: Reorient or relocate the receiving antenna; In-
crease the separation between the equipment and receiver; Connect
the equipment into an outlet on a circuit different from that to
which the receiver is connected; Consult the dealer or an experi-
enced radio/TV technician for help.

The responsible party for this device’s compliance is:
