Follow these safety, ESD, and servicing precautions to prevent personal injury and equipment damage.

1-1 Safety Precautions

1. Be sure that all built-in protective devices are in
place. Restore any missing protective shields.

2. Make sure there are no cabinet openings
through which people- particularly children­might insert fingers or objects and contact
dangerous voltages.

3. When re-installing chassis and assemblies, be
sure to restore all protective devices, including
control knobs and compartment covers.

4. Design Alteration Warning:
Never alter or add to the mechanical or electrical
design of this equipment, such as auxiliary
connectors, etc. Such alterations and
modifications will void the manufacturer's
warranty.

5. Components, parts, and wiring that appear to
have overheated or are otherwise damaged
should be replaced with parts which meet the
original specifications. Always determine the
cause of damage or overheating, and correct any
potential hazards.

6. Observe the original lead dress, especially near
sharp edges, AC, and high voltage power
supplies. Always inspect for pinched, out-of­place, or frayed wiring. Do not change the
spacing between components and the printed
circuit board.

7. Product Safety Notice:
Some electrical and mechanical parts have

special safety-related characteristics which might
not be obvious from visual inspection. These
safety features and the protection they provide
could be lost if a replacement component differs
from the original. This holds true, even though
the replacement may be rated for higher voltage,
wattage, etc.

Components critical for safety are indicated in

the parts list with symbols . Use only
replacement components that have the same
ratings, especially for flame resistance and
dielectric specifications. A replacement part that
does not have the same safety characteristics as
the original may create shock, fire, or other
safety hazards.

1-2 ESD Precautions

Certain semiconductor devices can be easily
damaged by static electricity. Such components are
commonly called "Electrostatically Sensitive (ES)
Devices", or ESDs. Examples of typical ESDs are:
integrated circuits, some field effect transistors, and
semiconductor "chip" components.
The techniques outlined below should be followed
to help reduce the incidence of component damage
caused by static electricity.

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

1. Immediately before handling a semiconductor
component or semiconductor-equipped
assembly, drain off any electrostatic charge on
your body by touching a known earth ground.
Alternatively, employ a commercially available
wrist strap device, which should be removed for

your personal safety reasons prior to applying power
to the unit under test.

2. After removing an electrical assembly equipped
with ESDs, place the assembly on a conductive
surface, such as aluminum or copper foil, or
conductive foam, to prevent electrostatic charge
buildup in the vicinity of the assembly.

3. Use only a grounded tip soldering iron to solder
or desolder ESDs.

4. Use only an "anti-static" solder removal device.
Some solder removal devices not classified as
"anti-static" can generate electrical charges
sufficient to damage ESDs.

5. Do not use Freon-propelled chemicals. When
sprayed, these can generate electrical charges
sufficient to damage ESDs.

6. Do not remove a replacement ESD from its
protective packaging until immediately before
installing it. Most replacement ESDs are
packaged with all leads shorted together by
conductive foam, aluminum foil, or a
comparable conductive material.

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

8. Maintain continuous electrical contact between
the ESD and the assembly into which it will be
installed, until completely plugged or soldered
into the circuit.

9. Minimize bodily motions when handling
unpackaged replacement ESDs. Normal
motions, such as the brushing together of
clothing fabric and lifting one's foot from a
carpeted floor, can generate static electricity
sufficient to damage an ESD.

1. Exercise caution when replacing a Lithium
battery. There could be a danger of explosion
and subsequent operator injury and/or
equipment damage if incorrectly installed.

2. Be sure to replace the battery with the same or
equivalent type recommended by the
manufacturer.

3. Lithium batteries contain toxic substances and
should not be opened, crushed, or burned for
disposal.
