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 SECR. 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 recomm-
ended 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 comp-
onents 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, (
Use replacement components that have the same
ratings, especially for flame resistance and dielectric
strength specifications.
does not have the same safety characteristics as the
original might create shock, fire or other hazards.
