Precaution Statements; Safety Precautions - Sam4s ER-280 SERIES Service Manual

1 Precaution Statements

Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards
such as electrical shock.

1-1 Safety Precautions

1. Be sure that all built-in protective devices are
replaced. Restore any missing protective
shields.
2. When reinstalling the chassis and its
assemblies, be sure to restore all protective
devices, including nonmetallic control knobs and
compartment covers.
3. Make sure there are no cabinet openings
through which people - particularly children -
might insert fingers and contact dangerous
voltages.
Such openings include excessively wide cabinet
ventilation slots and improperly fitted covers and
drawers.
4. Design Alteration Warning:
Never alter or add to the mechanical or
electrical design of the ECR. Unauthorized
alterations might create a safety hazard. Also,
any design changes or additions will void the
manufacturer's warranty.
5. Components, parts and wiring that appear to
have overheated or that are otherwise damaged
should be replaced with parts that meet the
original specifications. Always determine the
cause of damage or over- heating, and correct
any potential hazards.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the manufacturer.
Dispose used batteries according to the
manufacturer's instructions.

6. Observe the original lead dress, especially near
the following areas: sharp edges, and especially
the AC and high voltage supplies.
Always inspect for pinched, out-of-place, or
frayed wiring. Do not change the spacing
between components and the printed circuit
board. Check the AC power cord for damage.
Make sure that leads and components do not
touch thermally hot parts.
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
give might be lost if the replacement component
differs from the original - even if the
replacement is rated for higher voltage, wattage,
etc.
Components that are critical for safety are
indicated in the circuit diagram by shading, (
or ( ). Use replacement components that have
the same ratings, especially for flame
resistance and dielectric strength specifications.
A replacement part that does not have the
same safety characteristics as the original might
create shock, fire or other hazards.
ATTENTION
ll y a danger d'explosion s'il y a remplacement
incorrect de la batterie.
Remplacer uniquement avec une batterie du même
type ou d'un type équivalent recommandé par le
constructeur.
Mettre au rebut les batteries usagées conformément
aux instructions du fabricant.
